Including astrocytes, oligodendrocytes, and Schwann cells, for 10 points, are which components of neural tissue that support and nourish neurons?
Tumors originating from one type of these cells are identified by perivascular rosettes, and HIV-1's Tat protein can increase expression of the JC virus genome in these cells. One subtype is marked by enlarged processes and eosinophilic cytoplasm. Members of another subtype of these cells are functionally influenced by a namesake fibrillary acidic protein, and are called gemistocytes. Other groups include those which secrete a thick protein-rich fluid, known as ependymal cells. Some of these cells direct the migration of neurons, while others tightly regulate which compounds diffuse into the brain from blood vessels. One type synthesizes growth factors following Wallerian degeneration and wraps its cell membrane multiple times around portions of adjacent cells, forming a myelin sheath.
