Glial scar hand, absence of the glial scar has been associated with impairments in the repair of the blood brain barrier. The glial scar is composed of several components briefly discussed below. Reactive astrocytes are the main cellular component of the glial scar. After injury, astrocytes undergo morphological changes, extend their processes, and increase synthesis of glial fibrillary acidic protein (GFAP). GFAP is an important intermediate filament protein that allows the astrocytes to begin synthesizing more cytoskeletal supportive structures and extend pseudopodia. Ultimately, the astrocytes form a dense web of their plasma membrane extensions that fills the empty space generated by the
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
