The choroid plexus, or plica choroidea, is a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain. [1] Regions of the choroid plexus produce and secrete most of the cerebrospinal fluid (CSF) of the central nervous system.

2023年7月24日 · It is a highly organized tissue that lines all the ventricles of the brain except the frontal/occipital horn of the lateral ventricles and the cerebral aqueduct. The choroid plexus has a lining of specialized epithelial tissue known as ependyma.

2023年8月24日 · The cerebral aqueduct is void of choroid plexus. The choroid plexus is located in the posterior medullary velum which partially forms the roof of the fourth ventricle. The choroid plexus is supplied by the branches of the posterior inferior cerebellar arteries.

Studies of the choroid plexus lag behind those of the more widely known blood-brain barrier, despite a much longer history. This review has two overall aims. The first is to outline long-standing areas of research where there are unanswered questions, such as control of cerebrospinal fluid (CSF) secretion and blood flow.

2024年7月19日 · The choroid plexus is located within the cerebral ventricles and is made of choroidal epithelial cells (type of ependymal cell), loose connective tissue (tela choroidea), and permeable capillaries. It produces cerebrospinal fluid. The choroid plexuses also form the blood-CSF barrier alongside arachnoid and arachnoid villi 2.

2020年6月27日 · The choroid plexus or plica choroidea borders the membrane of the pia mater and the ventricles of the brain. It is an area of specialized cells that surrounds a direct blood source (capillary). The choroid plexus also plays neuroendocrine, neuro …

2021年5月27日 · The choroid plexus (ChP) in each brain ventricle produces cerebrospinal fluid (CSF) and forms the blood-CSF barrier. Here, we construct a single-cell and spatial atlas of each ChP in the developing, adult, and aged mouse brain.

2019年11月13日 · The choroid plexus is a network of capillaries and specialized ependymal cells found in the cerebral ventricles of the brain. The choroid plexus serves two roles for the body: it produces cerebrospinal fluid and provides a toxin barrier to …

CSF represents not only a mechanical brain protection but also a rich source of signalling factors modulating diverse processes during brain development and adulthood. The choroid plexus (CP) is a major source of CSF and as such it has recently emerged as an important mediator of extracellular signalling within the brain.

2015年7月15日 · Recent work in the field has identified several ChP-derived factors with important roles in the developing and adult brain. Importantly, the ChP epithelial cell secretome has been described,...
