  • [Title] The multifunctional choroid.
  • The choroid of the eye is primarily a vascular structure supplying the outer retina.
  • It has several unusual features: It contains large membrane-lined lacunae, which, at least in birds, function as part of the lymphatic drainage of the eye and which can change their volume dramatically, thereby changing the thickness of the choroid as much as four-fold over a few days (much less in primates).
  • It contains non-vascular smooth muscle cells, especially behind the fovea, the contraction of which may thin the choroid, thereby opposing the thickening caused by expansion of the lacunae.
  • The choroid has several functions: Its vasculature is the major supply for the outer retina; impairment of the flow of oxygen from choroid to retina may cause Age-Related Macular Degeneration.
  • In addition to its vascular functions, the choroid contains secretory cells, probably involved in modulation of vascularization and in growth of the sclera.
  • Finally, the dramatic changes in choroidal thickness move the retina forward and back, bringing the photoreceptors into the plane of focus, a function demonstrated by the thinning of the choroid that occurs when the focal plane is moved back by the wearing of negative lenses, and, conversely, by the thickening that occurs when positive lenses are worn.
  • Because transient increases in choroidal thickness are followed by a prolonged decrease in synthesis of extracellular matrix molecules and a slowing of ocular elongation, and attempts to decouple the choroidal and scleral changes have largely failed, it seems that the thickening of the choroid may be mechanistically linked to the scleral synthesis of macromolecules, and thus may play an important role in the homeostatic control of eye growth, and, consequently, in the etiology of myopia and hyperopia.

  • [Title] Choroid plexus papilloma in children: Diagnostic and surgical considerations.
  • BACKGROUND: Choroid plexus papilloma (CPP) is a benign neoplasm that arises from the ventricular choroid plexus.
  • CONCLUSIONS: Coagulation of the tumor under constant irrigation to shrink and excise it in toto, avoids excessive bleeding during surgery.
  • The vascular pedicle supplying the tumor should be adequately dealt with during the last part of tumor removal as retraction of a bleeding pedicle may result in ventricular hemorrhage and brain edema.

  • The Kearns-Sayre syndrome is a mitochondrial disorder (generally due to mitochondrial DNA deletions) that causes ophthalmoplegia, retinopathy, ataxia and brain abnormalities such as leukoencephalopathy.
  • In this syndrome, the choroid plexus epithelial cells, unlike brain cells, are greatly enlarged and granular, consistent with their inability to adequately transport folate from blood into cerebrospinal fluid (CSF), and homovanillic acid (a dopamine metabolite) from CSF into blood.
  • The Kearns-Sayre syndrome is a disease that interferes with key choroid plexus functions and is a cause of generalized choroid plexus failure.

  • A case of ossifying choroid plexus papilloma (CPP) with an unusual clinical course is reported.
  • The patient was a 46-year-old woman who underwent surgery for a 3-cm tumor occupying the fourth ventricle.
  • The tumor showed typical histopathological features of CPP, and the formation of psammoma bodies and mature bone trabeculae was prominent in the stroma.
  • The tumor recurred locally after a dormant period of 15 years, and the recurrent lesion showed invasion of the cerebellum as well as increased cellularity, cellular stratification, nuclear atypism, and mitotic activity, all of which were consistent with a diagnosis of "atypical" CPP.
  • The recurrent tumor did not show ossification of the stroma, although many psammoma bodies were found.
  • There have been very few reported cases of ossifying CPP, and all of the previous cases behaved in a benign fashion.

  • Cerebrospinal metastases of benign choroid plexus papillomas (CPPs) are extremely rare.
  • Plain CT scan of the cranium revealed a partly calcified tumor filling the fourth ventricle and its right recess.
  • Cranial MRI showed an inhomogeneously contrast-enhancing tumor and leptomeningeal enhancement encasing the brain stem.
  • Complete resection of the tumor was carried out, and seedings to the floor of the fourth ventricle and cervico-medullary junction were found during the operation.
  • While intraoperative frozen section suggested pathology of papillary ependymoma or CPP, to our surprise, final histological examination revealed a benign choroid plexus papilloma.
  • This special case helps increase our understanding of benign CPPs and expands our differential diagnostic consideration of lesions with similar manifestations.

  • Choroid plexus carcinoma is an uncommon neoplasm of the central nervous system most commonly found in the pediatric population.
  • Accurate histopathologic diagnosis is imperative, and this neoplasm should always be included in the differential diagnosis of a papillary intraventricular tumor.
  • Histopathologic features include blurring of papillary architecture, layers of neoplastic choroid plexus epithelial cells with pleomorphic nuclei, increased nuclear-to-cytoplasmic ratio, increased mitotic activity, areas of necrosis, and brain invasion.
  • Current accepted treatment is gross total surgical resection of the tumor as the goal.

  • [Title] Diffuse villous hyperplasia of choroid plexus.
  • Diffuse villous hyperplasia of choroid plexus (DVHCP) is a rare condition which is characterized by the presence of diffuse enlargement of the entire choroid plexus throughout the length of the choroidal fissure and overproduction of CSF.
  • The diagnosis of diffuse villous hyperplasia of choroid plexus can be established by the MR demonstration of diffusely large, contrast enhanced choroid plexus in the cases of overproduction hydrocephalus.
  • Although some authors recommend choroid plexus excision or coagulation, ventriculo-atrial shunt insertion is a simple and effective treatment modality in cases of diffuse villous hyperplasia of the choroid plexus.
  • In this report we present a case of diffuse villous hyperplasia of the choroid plexus and a short review of the literature.

  • The choroid plexus is a specialized tissue that lines subdomains within the four ventricles of the brain where most of the cerebrospinal fluid is produced.
  • The necessarily high water permeability of the choroid plexus barrier is made possible by the abundant expression of a water channel, Aquaporin-1 (AQP1), on the apical side of the membrane from early stages of development through adulthood.
  • Several signaling cascades have a direct effect on transporters and ion channels present in the choroid plexus epithelium, altering their transport activity and therefore modulating the net transcellular movement of solutes and water.
  • The mammalian choroid plexus receives innervation from noradrenergic sympathetic fibers, cholinergic and peptidergic fibers that modulate CSF secretion.

  • [Title] Choroid plexus: biology and pathology.
  • The choroid plexus is an epithelial-endothelial vascular convolute within the ventricular system of the vertebrate brain.
  • The choroid plexus is mainly involved in the production of cerebrospinal fluid (CSF) by using the free access to the blood compartment of the leaky vessels.
  • In order to separate blood and CSF compartments, choroid plexus epithelial cells and tanycytes of circumventricular organs constitute the blood-CSF-brain barrier.
  • As non-neuronal cells in the brain and derived from neuroectoderm, choroid plexus epithelia are defined as a subtype of macroglia.
  • The choroid plexus is involved in a variety of neurological disorders, including neurodegenerative, inflammatory, infectious, traumatic, neoplastic, and systemic diseases.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Psammoma bodies - friends or foes of the aging choroid plexus.
  • Psammoma bodies are structures classified in the group of dystrophic calcifications, which occur in some kind of tumors and in choroid plexus during the aging process.
  • Despite early discovery of their presence in choroid plexus stroma, mechanisms responsible for their formation remained unclear.
  • Also, there are not any data about structural differences between ones found in tumors and ones found in choroid plexus.
  • This might points to the assumption that besides the aging, some other causes might be involved in their formation in choroid plexus.
  • Furthermore, it is contradictory that forms, like psammoma bodies, present in such malignant formations as tumors, represent quite benign phenomenon in choroid plexus.
  • Firstly, psammoma bodies are present in stroma of tumors with predominantly papillomatous morphology, which is present in choroid plexus, too.
  • Initial forms of psammoma bodies might be formed in fibrovascular core of choroid plexus villi, similarly like in tumors papillae of papillary thyroid cancer.
  • Choroid plexus stroma is characterized by the fenestrated blood vessels presence, which are similar to newly formed vessels in tumors.
  • So, all these facts can suggest that similar processes can lead to psammoma bodies formation in both tumors and choroid plexus and, that they might have harmful effect on choroid plexus structure and function during the aging process.
  • Further researches should be focused on detection of osteopontin and nanobacteria, already detected in tumors psammoma bodies, in choroid plexus ones.
  • Application of choroid plexus epithelial cells functional markers in cases with psammoma bodies should show their functional status.

  • [Title] Choroid plexus papilloma with neuropil-like islands.
  • Choroid plexus papilloma may display unusual histologic features, but the presence of neuronal differentiation at the light microscopic level has not yet been described.
  • We thus report a choroid plexus papilloma with neuropil-like islands located within the lateral ventricle of an 11-year-old girl.
  • The absence of atypical histologic features associated with recurrence (particularly increased mitotic activity) and recurrence-free follow-up upon gross total resection are compatible with a diagnosis of choroid plexus papilloma (WHO grade I).
  • This case further emphasizes the capacity of choroid plexus tumor cells toward neuronal differentiation, and expands the spectrum of tumors, which may contain neuropil-like islands.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Malignant progression in choroid plexus papillomas.
  • OBJECT: Malignant progression of choroid plexus papillomas has been occasionally reported, but this issue has not yet been systematically addressed.
  • METHODS: Frequency and extent of malignant progression were examined in a retrospective series of 124 primary choroid plexus papillomas using uniform histological criteria.
  • RESULTS: After gross-total resection and a mean follow-up period of 59 months, 12 recurrences necessitating neurosurgical intervention had occurred in the 103 cases of choroid plexus papilloma (World Health Organization [WHO] Grade I) and 21 cases of atypical choroid plexus papilloma (WHO Grade II).
  • The proportion of recurring tumors was higher in cases of atypical choroid plexus papilloma than in cases of choroid plexus papilloma (six [29%] of 21 compared with six [6%] of 103, respectively; p < 0.05).
  • In the majority (10 of 12) of the recurrences, there was a close correspondence between the primary tumor and the recurrence with respect to features identified on routine histological examination as well as Ki 67 (MIB-1) proliferation indices (median value 4% for both primary and recurrent tumors; range 0-15% for primary compared with 0-12% for recurrent tumors).
  • However, two patients experienced a transition from a choroid plexus papilloma (WHO Grade I) and an atypical choroid plexus papilloma (WHO Grade II) to choroid plexus carcinomas (WHO Grade III).
  • CONCLUSIONS: Recurrent tumor growth after gross-total resection is rare in choroid plexus papillomas, but malignant progression to choroid plexus carcinoma does occur in a small percentage of tumors.

  • BACKGROUND: Choroid plexus papillomas are rare tumors of the central nervous system and are usually confined to the ventricle system.
  • We describe a choroid plexus papilloma located in the sella turcica that was identified pathologically.
  • Histologic examination proved that the lesion was a choroid plexus papilloma.
  • CONCLUSION: Choroid plexus papillomas arising in and occupying the sella are rare, although some radiographic patterns of ectopic choroid plexus papillomas have been reported.
  • A review of the current literature revealed no similar cases of a choroid plexus papilloma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Aquaporin(s) expression in choroid plexus tumours.
  • OBJECTIVE: It was the aim of this study to investigate the pattern of aquaporin 1 (AQP1) expression in normal and neoplastic choroid plexus, with specific reference to the association with communicating hydrocephalus or liquoral cysts.
  • Second, to infer a new view on the cerebrospinal fluid plexus production and on the etiology of the cysts and communicating hydrocephalus occasionally associated with choroid plexus papillomas.
  • MATERIALS AND METHODS: Nineteen paraffin-embedded specimens, 10 of normal choroid plexus and 9 of choroid plexus tumours, were immunostained with a monoclonal antibody raised against the intracellular C-terminal AQP1 epitope.
  • RESULTS: AQP1 was heavily expressed in the apical side of the choroid epithelium in normal plexus specimens.
  • Choroid plexus papillomas showed a very heterogeneous pattern of AQP1 expression.
  • Immunostaining was absent in the case of choroid plexus carcinoma.
  • CONCLUSIONS: AQP1 expression characterizes normal choroid plexus and plexus papillomas.
  • Intensity and diffusion of AQP1 expression together with the size of the tumour mass are somewhat predictive of communicating hydrocephalus or liquoral cyst, lesions possibly caused by a disturbance of cerebrospinal fluid homeostasis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Aquaporin-1 in the choroid plexuses of developing mammalian brain.
  • Because of limited vascularisation of the immature brain, choroid plexuses, via the cerebrospinal fluid, have been proposed as the main route of fluid exchange between the blood and brain interfaces.
  • We describe the temporal expression and appearance of aquaporin-1 (AQP1) which is important for water transfer across adult choroid plexuses.
  • AQP1 expression was studied in rat embryos using real time reverse transcription/polymerase chain reaction. mRNA for AQP1 was present in rat brain at embryonic day 12 (E12) one day before the protein was detectable in the fourth ventricular choroid plexus (the first plexus to appear); its relative levels increased at E13-E14 when more AQP1-immunoreactive cells appeared in all plexuses.
  • The presence of AQP1 was determined immunocytochemically in five different mammalian species (rat, mouse, human, sheep and opossum) in all four choroid plexuses from their earliest appearance.
  • In all five species studied, the appearance of AQP1 immunoreactivity followed the same developmental sequence: the fourth, lateral and, finally, third ventricular choroid plexus.
  • The stage of choroid plexus development when AQP1 was first detected in all five species and in all four choroid plexuses corresponded to the transition between Stages I and II.
  • The cellular localisation of AQP1 in all choroid plexuses, as soon as it was detectable, had the characteristic apical membrane distribution previously described in the adult; a basolateral membrane localisation was also observed.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Clearance of amyloid-β peptide across the choroid plexus in Alzheimer's disease.
  • Aging and several neurodegenerative diseases bring about changes in the anatomy and physiology of the choroid plexus.
  • Faulty Aβ clearance from the brain across the choroid plexus epithelium by megalin appears to mediate focal Aβ accumulation in AD.
  • Patients with AD have reduced levels of megalin at the choroid plexus, which in turn seem to increase brain levels of Aβ through a decreased efflux of brain Aβ.
  • Therapies that increase megalin expression at the choroid plexus could potentially control accumulation of brain Aβ.
  • This review covers in depth the anatomy and function of the choroid plexus, focusing on the brain barrier at the choroid plexus, as it actively participates in Aβ clearance.
  • In addition, we describe the role of the choroid plexus in brain functions, aging and AD, as well as the role of megalin in the process of Aβ clearance.
  • Finally, we present current data on the use of choroid plexus cells to repair the damaged brain.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Asymmetric localization of Notch2 on the microvillous surface in choroid plexus epithelial cells.
  • In the brain, Notch2, but not the other members of Notch, is expressed in the choroid plexus at an exceptionally high level.
  • We immunohistochemically examined the cellular and subcellular localization of Notch2 protein in the choroid plexus using confocal and electron microscopy.
  • Unexpectedly, Notch2 was asymmetrically localized on the microvillous surface of epithelial cells in the choroid plexus of both postnatal and adult rats.
  • This localization pattern of Notch2 suggests its novel and unknown role independent of contact with adjacent cells in the choroid plexus.
  • In organotypic cultures of the choroid plexus, the addition of anti-Notch2 antibody resulted in deformation of microvilli in epithelial cells, which suggests a role of Notch2 in the maintenance of the microvillous structure in choroid plexus epithelial cells.

  • [Title] Choroid plexitis in a case of systemic nocardiosis.
  • Although rare, primary choroid plexitis can occur as an early presentation of a central nervous system (CNS) infection most commonly with cryptococcosis, tuberculosis, and nocardiosis.
  • In the appropriate clinical setting, an enlarged, intensely enhancing choroid plexus should raise suspicion for choroid plexitis.
  • We review the existing literature and present a case of infectious choroid plexitis in a patient with systemic nocardiosis; computed tomography and magnetic resonance imaging demonstrated the characteristic findings of choroid plexitis, which later developed into a parenchymal abscess.

  • Amongst the primary ventricular forms occasionally reported, a choroid plexus origin is extremely rare; to date, only three cases have been described in the English literature.
  • She underwent a parieto-occipital craniotomy and a navigation-assisted posterior parietal transcortical approach, achieving complete removal of the intraventricular lesion originating from the choroid plexus.
  • The histological diagnosis was of high-grade diffuse large B-cell lymphoma.
  • Both an MRI scan of the entire craniospinal axis and a thoracic and abdominal CT scan showed no other neoplastic lesions; a bone marrow biopsy was normal; a final diagnosis of primary central nervous system lymphoma was made.
  • Primary choroid plexus lymphoma is a very rare tumor that should be included in the differential diagnosis of intraventricular neoplasms.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Derivation of primary choroid plexus epithelial cells from the mouse.
  • Choroid plexus epithelial cells form an integral and important part of the barrier between blood and cerebrospinal fluid.
  • Culture of choroid plexus epithelium in vitro has been achieved from several mammalian species and this provides opportunities for the study of choroid plexus development and function, including the capacity of the epithelial cells to control the movement of bioactive molecules, such as novel drug candidates, from the bloodstream to the brain.
  • Here we describe a method for the derivation of primary cell cultures from mouse choroid plexus epithelium, together with characterisation by immunofluorescence using antibodies specific to markers of mature choroid plexus epithelial cells.
  • With this method, relatively pure choroid plexus epithelial cell monolayers are established using the DNA synthesis inhibitor cytosine arabinoside (Ara-C), which is cytotoxic to contaminating cell types such as fibroblasts, but not the epithelial cells.
  • These cells are shown to express the diagnostic choroidal marker, transthyretin (TTR), as well as markers of epithelial cell differentiation and are thus suitable for studies that address the transport and barrier functions of the choroid plexus.

  • However, in papillomas it is by nests of tumour cells compared with carcinomas wherein invasion is by individual tumour cells.
  • Hydrocephalus is present irrespective of location and size of the tumour.
  • Large tumour size, excessive blood loss, higher incidence of carcinomas result in partial excision of these tumours in the paediatric group.
  • Subdural collections and tumour bed haematomas are more common complications in the paediatric group after resection of tumour.

  • [Title] Age-related changes in sympathetic neurotransmission in rat retina and choroid.
  • While age-related night vision loss and age-related macular degeneration are well characterized, less is known about the normal aging process in the retina and choroid.
  • The purpose of this study was to ascertain whether dopamine beta-hydroxylase (DBH), beta1- and beta2-adrenergic receptor gene and protein expression are altered in the retina and choroid with age.
  • The retina and choroid were dissected from F344xBNF1 hybrid rats aged 8, 22, and 32 months.
  • DBH protein expression was substantially decreased with age in the retina, particularly in the outer nuclear layer, with no changes in DBH expression noted in the choroid.
  • Gene expression for DBH, beta1- and beta2-adrenergic receptors were observed to peak at 22 months and return to baseline levels by 32 months of age in the choroid.
  • Our findings suggest that the retina may be more sensitive to age-related loss of sympathetic neurotransmission than the choroid, which may partially explain normal age-related vision loss in the elderly.

  • BACKGROUND: The choroid plexus (ChP), a component of the blood-brain barrier (BBB), produces the cerebrospinal fluid (CSF) and as a result plays a role in (i) protecting and nurturing the brain as well as (ii) in coordinating neuronal migration during neurodevelopment.
  • This process includes the formation of the tela choroidea (TC), the recruitment of cells from rhombic lips and, finally, the coalescence of TC resulting in formation of ChP.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Distribution of sodium transporters and aquaporin-1 in the human choroid plexus.
  • The choroid plexus epithelium secretes electrolytes and fluid in the brain ventricular lumen at high rates.
  • Several channels and ion carriers have been identified as likely mediators of this transport in rodent choroid plexus.
  • This study aimed to map several of these proteins to the human choroid plexus.
  • The Na(+)-K(+)-ATPase alpha(1)-subunit was exclusively localized apically in the human choroid plexus epithelial cells.
  • Hence, the human choroid plexus epithelium displays an almost identical distribution pattern of water channels and Na(+) transporters as the rat and mouse choroid plexus.
  • This general cross species pattern suggests central roles for these transporters in choroid plexus functions such as cerebrospinal fluid production.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Immunohistochemical analysis of CDX2 expression in normal choroid plexus epithelium and choroid plexus tumors.
  • BACKGROUND: The Wnt and BMP signaling pathways are involved in the morphogenesis of both gastrointestinal and choroid plexus epithelium.
  • In the intestine, Wnt signaling represses the expression of the tumor suppressor gene CDX2 via SOX9, a transcription factor, which is also expressed in the choroid plexus.
  • Recently, an inverse correlation between CDX2 expression and tumor grade, tumor stage and lymph node metastasis in colorectal adenocarcinomas has been reported.
  • To date, no data exist on expression of CDX2 in normal and neoplastic choroid plexus epithelium.
  • AIM: To investigate CDX2 expression in normal and neoplastic choroid plexus.
  • MATERIALS AND METHODS: Paraffin-embedded samples from 60 normal choroid plexus, including 23 fetal tissue samples and from 65 choroid plexus tumors (47 choroid plexus papillomas WHO grade I, 16 atypical choroid plexus papillomas and 2 choroid plexus carcinomas WHO grade III) were examined by immunohistochemistry.
  • Samples from normal choroid plexus were collected from 45 autopsy cases and from 15 neurosurgical specimens.
  • RESULTS: Normal and neoplastic choroid plexus lacked CDX2 expression.
  • CONCLUSION: In our series, immunohistochemistry shows no evidence for a role of CDX2 in development or differentiation of normal choroid plexus from the 9th gestational week until adulthood.
  • Since choroid plexus tumors reliably lack CDX2 immunoreactivity, this marker may be helpful in distinguishing cerebral metastases from CDX2-positive adenocarcinomas and choroid plexus neoplasms.

  • [Title] Diffuse choroid plexus hyperplasia: an under-diagnosed cause of hydrocephalus in children?
  • Hydrocephalus is a common neurological disorder in children and the result of a variety of causes.
  • We report an 11-year-old boy with diffuse villous hyperplasia of the choroid plexus.
  • He had a ventriculo-peritoneal (VP) shunt in-situ and a prior diagnosis from infancy of congenital aqueduct stenosis as the cause of his hydrocephalus.
  • CT and MRI demonstrated enlarged choroid plexuses but did not confirm aqueduct stenosis.
  • The enlarged choroid plexuses were surgically resected and histology confirmed choroid plexus hyperplasia.
  • Identification of choroid plexus hyperplasia is important since the neurosurgical management of hydrocephalus is not VP shunt insertion, but resection of the hyperplastic choroid plexus.

  • [Title] The choroid plexus removes beta-amyloid from brain cerebrospinal fluid.
  • beta-Amyloid (Abeta) concentration in the cerebrospinal fluid (CSF) of the brain may be regulated by the choroid plexus, which forms a barrier between blood and brain CSF.
  • Abeta uptake from CSF was determined as its volume of distribution (V(D)) into isolated rat choroid plexus tissue.
  • Abeta uptake into choroid plexus was time and temperature dependent.
  • Overall, these results suggest the choroid plexus selectively cleanses Abeta from the CSF by an undetermined mechanism(s), potentially reducing Abeta from normal brains and the brains of Alzheimer's disease patients.

  • [Title] Sonic hedgehog is required for vascular outgrowth in the hindbrain choroid plexus.
  • Critical to the exchange and metabolic functions served by tissues like brain choroid plexi and lung is the coherent development of an epithelial sheet of large surface area in tight apposition to an extensive vascular bed.
  • Here, we present functional experiments in the mouse demonstrating that Sonic hedgehog (Shh) produced by hindbrain choroid plexus epithelium induces the extensive vascular outgrowths and vascular surface area fundamental to choroid plexus functions, but does not induce the more specialized endothelial cell features of fenestrations and bore size.
  • Our findings indicate that these Shh-dependent vascular elaborations occur even in the presence of Vegf and other established angiogenic factors, suggesting either that the levels of these factors are inadequate in the absence of Shh or that a different set of factors may be more essential to choroid plexus outgrowth.
  • Moreover, our findings suggest that hindbrain choroid plexus endothelial cells, as compared to other vascular endothelial cells, are more dependent upon pericytes for instruction.
  • Thus, in addition to Shh acting on the progenitor pool for choroid plexus epithelial cells, as previously shown, it also acts on choroid plexus pericytes, and together serves the important role of coordinating the development of two disparate yet functionally dependent structures-the choroid plexus vasculature and its ensheathing epithelium.

  • [Title] An experimental study of the elastic properties of the human Bruch's membrane-choroid complex: relevance to ageing.
  • AIM: To investigate the mechanical properties (stress-strain relation, elasticity, hysteresis, response to stress spikes and drops) of isolated human Bruch's membrane-choroid, as well as the effect of ageing and aged related macular degeneration (AMD).
  • METHODS: 13 Bruch's membrane-choroid complexes were obtained from human donors (21-97 years).
  • RESULTS: The elasticity of human Bruch's membrane-choroid complex decreased linearly with ageing (p<0.001) after the age of 21 with an approximate reduction of 1% per year.
  • The recoil capacity of Bruch's membrane-choroid was not affected by ageing.
  • CONCLUSION: The elasticity of Bruch's membrane-choroid complex decreases with age while recoil capacity does not.

  • [Title] Structural and functional features of choroid epithelium from buffalo brain.
  • Choroid plexuses (CPs) play pivotal roles in many processes that establish, survey, and maintain the biochemical and cellular status of the central nervous system (CNS).
  • Here, we report structural and functional features of choroid epithelium from buffalo brain never described before.
  • The second type of cells resulted to be formed by a globular body from which depart numerous processes; these cells, localized deeply in the choroid epithelium, strictly contact neighboring epithelial cells.
  • To gain some insight into the functional properties of choroid cells, NADPH diaphorase (NADPHd) and neuronal nitric oxide synthase (nNOS) activities were evaluated.
  • Of interest, whereas a strong NADPHd activity was detected in all cell types of choroid epithelium, nNOS was only detected in the first type of peculiar cells.

  • [Title] Kinetic profile of the transcriptome changes induced in the choroid plexus by peripheral inflammation.
  • The choroid plexus, being part of the blood-brain barriers and responsible for the production of cerebrospinal fluid, is ideally positioned to transmit signals into and out of the brain.
  • This study, using microarray analysis, shows that the mouse choroid plexus displays an acute-phase response after an inflammatory stimulus induced in the periphery by lipopolysaccharide (LPS).
  • Importantly, several acute-phase proteins, whose blood concentrations rise in response to inflammation, may contribute to the effects observed in vivo after LPS injection, as suggested by the differential response of primary choroid plexus epithelial cell cultures to LPS alone or to serum collected from animals exposed to LPS.
  • By modulating the composition of the cerebrospinal fluid, which will ultimately influence the brain parenchyma, the choroid plexus response to inflammation may be of relevance in brain homeostasis in health and disease.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Changes in the spatial expression of genes with aging in the mouse RPE/choroid.
  • PURPOSE: We recently used microarray and reverse transcriptase PCR (RT-PCR) analysis to show an upregulation of cathepsin S (CatS) and glutathione peroxidase 3 (GPX3) in the aging mouse RPE/choroid.
  • To evaluate the mRNA distribution and levels in the RPE and choroid, in situ hybridizations were performed.
  • The ratio of mRNA labeled cells to total cells counted per section was compared between the two age groups for the RPE and choroid separately.
  • CONCLUSIONS: The increases in mRNA levels for CatS and GPX3 found in the aging C57BL/6 RPE/choroid appear to represent an increase in both the numbers of cells expressing these messages and an increase in the level of expression in individual cells.

  • The intensive metabolism of photoreceptors is delicately maintained by the retinal pigment epithelium (RPE) and the choroid.
  • Dysfunction of either the RPE or choroid may lead to severe damage to the retina.
  • Two-photon excited autofluorescence (TPEF) from endogenous fluorophores in the human retina provides a novel opportunity to reveal age-related structural abnormalities in the retina-choroid complex prior to apparent pathological manifestations of age-related retinal diseases.
  • Requiring neither slicing nor labeling, TPEF imaging is an elegant and highly efficient tool to delineate the thick, fragile, and opaque retina-choroid complex, and may provide clues to the trigger events of age-related macular degeneration.

  • [Title] Prognostic implications of atypical histologic features in choroid plexus papilloma.
  • The prognostic significance of atypical histologic features in choroid plexus tumors remains uncertain.
  • Therefore, a series of 164 choroid plexus tumors was evaluated for the presence of atypical histologic features, including mitotic activity, increased cellularity, nuclear pleomorphism, blurring of papillary growth pattern, and necrosis.
  • Twenty-four tumors displaying frank signs of malignancy were diagnosed as choroid plexus carcinoma according to World Health Organization criteria.
  • Of 124 choroid plexus papillomas that had not received adjuvant treatment, 46 tumors (37%) displayed at least one atypical feature, including increased cellularity (n = 25 [20%]), mitotic activity (> or =2 mitoses per 10 high-power fields; n = 19 [15%]), nuclear pleomorphism (n = 16 [13%]), solid growth (n = 15 [12%]), and necrosis (n = 5 [4%]).
  • Only one tumor-related death, but 10 recurrences, were observed on a mean observation time of 58 months.
  • Because mitotic activity is the sole atypical histologic feature independently associated with recurrence, we propose to define atypical choroid plexus papilloma by mitotic activity (> or =2 mitoses per 10 high-power fields) corresponding to World Health Organization grade II, thus adjoining other intermediate tumor entities associated with increased mitotic activity such as atypical meningioma.
  • Close follow up of patients harboring atypical choroid plexus papillomas may be warranted.

  • [Title] Choroid plexus hyperplasia: surgical treatment and immunohistochemical results. Case report.
  • Diffuse villous hyperplasia of the choroid plexus is a rare but potential source of nonobstructive hydrocephalus.
  • In addition to discussing the authors' staged surgical approach and medical management decisions in a patient with this rare and challenging condition, immunohistochemical studies of the choroid plexus epithelium are presented to examine the pathophysiological factors involved in abnormal cerebrospinal fluid (CSF) production in this disease.
  • The patient, a 15-month-old girl born at 36 weeks' gestation, underwent a bilateral craniotomy with resection of the choroid plexus to treat her villous hyperplasia.
  • Immunohistochemical studies of the resected choroid plexus were conducted for the purpose of examining the carbonic anhydrase II (CAII) enzyme and the aquaporin 1 (AQP1) membrane protein.
  • Results were compared with immunohistochemical studies conducted in a small series of autopsy specimens of normal human choroid plexuses.
  • Surgical removal of the affected choroid plexus is a feasible and effective treatment.
  • Results of the immunohistochemical studies reported here support the suggestion that the CAII enzyme is retained in villous hyperplasia of the choroid plexus.
  • However, there appears to be decreased expression and perhaps downregulation of AQP1 in villous hyperplasia compared with normal choroid plexus.

  • [Title] Bovine and porcine transscleral solute transport: influence of lipophilicity and the Choroid-Bruch's layer.
  • PURPOSE: To determine the influence of the choroid-Bruch's layer and solute lipophilicity on in vitro transscleral drug permeability in bovine and porcine eyes.
  • METHODS: The in vitro permeability of two VEGF inhibitory drugs, budesonide and celecoxib, which are lipophilic and neutral at physiologic pH, and of three marker solutes, 3H-mannitol (hydrophilic, neutral), sodium fluorescein (hydrophilic, anionic), and rhodamine 6G (lipophilic, cationic), were determined across freshly excised scleras, with or without the underlying choroid-Bruch's layer.
  • Select studies were performed using porcine sclera with and without choroid-Bruch's layer.
  • Partitioning of the solutes into bovine sclera and choroid-Bruch's layer was also determined.
  • The order of the permeability coefficients (Papp) across sclera and sclera-choroid-Bruch's layers in bovine and porcine models was 3H-mannitol > fluorescein > budesonide > celecoxib > rhodamine 6G, with HPbetaCD, and 3H-mannitol > fluorescein > rhodamine 6G, without HPbetaCD.
  • The presence of choroid-Bruch's layer reduced the bovine scleral permeability by 2-, 8-, 16-, 36-, and 50-fold and porcine tissue permeability by 2-, 7-, 15-, 33-, and 40-fold, respectively, for mannitol, sodium fluorescein, budesonide, celecoxib, and rhodamine 6G.
  • The partition coefficient ratio of bovine choroid-Bruch's layer to sclera was approximately 1, 1.5, 1.7, 2, and 3.5, respectively, for the solutes, as listed earlier.
  • CONCLUSIONS: The choroid-Bruch's layer is a more significant barrier to drug transport than is sclera.

  • Choroid plexus papillomas, a common intraventricular tumor in children, can be difficult to distinguish radiographically from choroid plexus carcinomas and other common pediatric central nervous system (CNS) tumors.
  • In this study to overcome the limitations of current noninvasive imaging modalities, the authors use novel magnetic resonance (MR) spectroscopy techniques in vivo to elucidate the identifying biochemical features of choroid plexus tumors that may facilitate diagnosis and treatment.
  • On retrospective review, this series included three choroid plexus papillomas and three choroid plexus carcinomas.
  • The myo-inositol (mI) level was significantly higher in choroid plexus papillomas (> 10 mmol/kg), uniquely distinguishing these tumors from choroid plexus carcinomas and all other tumors.
  • Choroid plexus carcinomas, on the other hand, had significantly elevated levels of choline when compared with choroid plexus papillomas.
  • CONCLUSIONS: In this study the authors find that mI is a biochemical constituent that uniquely identifies choroid plexus papillomas and can be used as a noninvasive means of diagnosis and for follow-up evaluations in patients with this disease.

  • [Title] Expression of the serotonin transporter (SERT) in the choroid plexuses from buffalo brain.
  • Choroid plexuses (CPs) play pivotal roles in a wide range of processes that establish, survey, and maintain the biochemical and cellular status of the central nervous system.
  • By immunogold labeling in scanning electron microscopy, SERT immunoreactivity was found to be localized on the apical surface of the choroid epithelium.
  • In particular, SERT positivity was detected on the apical portion of villi, and both on the membrane and in the cytoplasm of grouped cells on the surface of the choroid epithelium.
  • Our findings provide the first report of SERT detection in the CPs of buffalo brain and indicate that this protein is locally synthesized from the choroid epithelial cells.

  • Congophilic birefringent amyloid deposits, with immunostaining for transthyretin (TTR) and amyloid P, associated with numerous coarse, enlarged and thick elastic fibres, are reported in the stroma of two choroid plexus papillomas, a finding not previously described in choroid plexus tumours.
  • The stromal TTR-amyloid deposits associated with abundant elastic fibres in tumours that occur in the choroid plexus may be related to the alteration (production/accumulation, insufficient breakdown and/or extracellular matrix modifications) of some of the choroid plexus functions (removal, target and source of polypeptides, including TTR synthesis) and may be of interest for future studies on choroid plexus polypeptide activity and on protein development into elastomeric and amyloidogenic microfibrils.

  • [Title] Ion channel function of aquaporin-1 natively expressed in choroid plexus.
  • Using primary cultures of rat choroid plexus, a brain tissue that secretes CSF and abundantly expresses AQP1, we confirmed the ion channel function of AQP1 and assessed its functional relevance.
  • Fluid transport assays with confluent polarized choroid plexus cultures showed that AQP1 current activation by 4.5 mum ANP decreases the normal basal-to-apical fluid transport in the choroid plexus; conversely, AQP1 block with 500 mum Cd2+ restores fluid transport.
  • The cGMP-gated conductance in the choroid plexus is lost with targeted knockdown of AQP1 by small interfering RNA (siRNA), as confirmed by immunocytochemistry and whole-cell patch electrophysiology of transiently transfected cells identified by enhanced green fluorescent protein.
  • Background K+ and Cl- currents in the choroid plexus were dissected from AQP1 currents using Cs-methanesulfonate recording salines; the background currents recorded in physiological salines were not affected by AQP1-siRNA treatment.

  • [Title] Primary choroid plexus papilloma of the sacral nerve roots.
  • The authors describe a unique case of a choroid plexus papilloma of the sacral nerve roots.
  • Contrast-enhanced spinal MR imaging showed a well-circumscribed, ovoid, homogeneously enhancing mass at the S1-2 level suggesting a diagnosis of ependymoma or schwannoma, and surgery allowed the identification and complete removal of a soft gray mass intimately adhering to the sacral nerve roots.
  • Histological examination revealed a tumor consisting of papillary structures lined by a single layer of columnar cells, with an immunophenotype that satisfied the diagnostic criteria of choroid plexus papilloma.
  • After diagnosis, contrast-enhanced brain MR imaging excluded the presence of a primary choroid plexus papilloma in the cerebral ventricles, thus ruling out a drop metastasis along the CSF pathways.
  • A review of the literature did not reveal any similar cases of choroid plexus papilloma, and so the authors also discuss the inclusion of primary or metastatic papillary tumors in this unusual location as part of the differential diagnosis.

  • [Title] Ultrastructural study of the lateral ventricle choroid plexus in experimental hydrocephalus in Wistar rats.
  • To detect possible ultrastructural alterations of the lateral ventricles choroid plexus (responsible for the CSF production), rats seven days after birth were submitted to an intracisternal injection of 20% kaolim (hydrated aluminum silicate) for the hydrocephalus induction.
  • Alterations found: presence of concentric cell membrane fragments, larger number of primary and secondary lysossomes, vacuoles, and cytoplasmic vesicles, and an enlargement of the intercellular space and between the basolateral interdigitation of the choroid epithelium.
  • The alterations observed are probably associated to an increase of the ventricular pressure, inducing morpho-functional effects on the choroid plexus integrity.
