Sam Schmidt Paralysis Foundation a cell body, which houses the nucleus. Axons and dendrites form extensions from the cell body. Glial cells are "nerve-helper" cells that provide structural support, nourishment and protection for neurons. Astrocytes, a kind of glial cell, are the primary support cells of the brain and spinal cord. They make and secrete proteins called neurotrophic factors, which assist in the maintenance of nerve cells in the central nervous system. They also break down and remove proteins or chemicals that might be harmful to neurons (for example, glutamate, a neurotransmitter that in excess causes cells to become overexcited and die by a
Satellite glial cell has been discovered that this receptor has an antagonist in the form of A-317491, which, when present, has the ability to reduce both the evoked and unprompted firing of various classes of spinal neurons, as well as to inhibit release of IL-1β. However, the outside influences of receptors P2X3 and P2Y1 are believed to complicate the interactions between P2X7 and its antagonist, making it a non-ideal target when using pharmacological strategy. P2Y receptors are also found on both neurons and glial cells. Their role is less clear than that of the P2X receptors, but it has been noted they have
