WitrynaAstrocytes are a type of glial cell that performs a wide range of functions in the nervous system. They provide structural support for neurons and help to maintain the proper chemical environment for neural activity. Astrocytes also play a role in regulating blood flow to the brain, and can release signaling molecules that modulate neural activity. WitrynaA genome-scale functional screening of a transcript library from brain tumors revealed that the microtubule regulator stathmin is an activator of TLR3-dependent signaling in astrocytes, inducing the same set of neuroprotective factors as the known TLR3 agonist polyinosinic:polycytidylic acid.
