Choroid Plexus Epithelial Cells (CPEC)

Choroid plexus epithelial cell（CPEC）is a kind of glial cells in the central nervous system. It is the pipe chamber cell wall formation ventricle choroid plexus at specialized. Choroid plexus epithelium secrete cerebrospinal fluid (CSF) and adjacent cells near the top are closely connected and cohesin zonule, blood-brain barrier (blood-CSF-barrier). This structure plays a very important role in the immune system of the central nervous system as well as the regulation of molecular substances in the peripheral environment. Choroid plexus of the main physiological functions and secretion regulation of cerebrospinal fluid to maintain central nervous system function in the steady state. The choroid plexus epithelial cells synthesize and secrete many growth factors and peptides, these substances for regional nutritionally functional damage to the cerebral vascular system.The Choroid plexus epithelial cells serve as an excellent model to study the exchange processes across blood-CSF barrier, CSF homeostasis.
