Arachnoid Granulations and Arachnoid Villi in Mammals
There has been no general agreement regarding the presence of arachnoid granidations and arachnoid villi in mammals. This seems to have arisen from the fact that various workers have used different criteria in distinguishing between the two terms — 'granula tion' and 'villus'. Luschka (1852) was the first to. define the structure observed macroscopically as an 'arachnoid granulation', while fo...
متن کاملExpression of P2X receptors in rat choroid plexus.
In this study, we have used reverse transcriptase polymerase chain reaction and immunocytochemistry to show that P2X1, P2X2, P2X4, P2X5, P2X6 and P2X7 receptor messenger RNA and protein are expressed in the rat choroid plexus taken from the fourth and lateral ventricles. In some epithelial cells, the apical surfaces were stained more intensely than the basal surfaces. Some of the epithelial cel...
متن کاملExpression of stanniocalcin in the epithelium of human choroid plexus.
Stanniocalcin (STC) is a 28 kD glycoprotein hormone originally found in bony fish in which it regulates calcium/phosphate homeostasis and protects against hypercalcemia. The recently characterized mammalian STC shows about 70% homology with fish STC. The epithelial cells of proximal tubuli in human and rat kidney and brain neurons have been found to express STC. Here we show that the epithelium...
متن کاملImmunohistochemical 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...
متن کاملIntracranial hypertension and giant arachnoid granulations.
We read with great interest the article by Arjona et al concerning a patient with intracranial hypertension (ICH) and giant arachnoid granulations (GAG). The patient was a non-obese male without known risk factors for ICH apart from left transverse sinus hypoplasia and several GAGs in both transverse sinuses. The authors suggested that arachnoid granulations (AGs) might be responsible for ICH b...
