Glial fibrillary acidic protein rodent brain. These isoforms include GFAP kappa, GFAP +1 and the currently best researched GFAP delta. GFAP delta appears to be linked with neural stem cells (NSCs) and may be involved in migration. GFAP+1 is an antibody which labels two isoforms. Although GFAP+1 positive astrocytes are supposedly not reactive astrocytes, they have a wide variety of morphologies including processes of up to 0.95mm (seen in the human brain). The expression of GFAP+1 positive astrocytes is linked with old age and the onset of AD pathology. Glial fibrillary acidic protein Glial fibrillary acidic protein (GFAP) is a protein that is encoded
Satellite glial cell these cells. Current research is revealing that SGCs are also able to respond to some of the same chemical stimuli as neurons. The research is ongoing and SGCs role in injury repair mechanisms is not yet fully understood. Glial cells, including SGCs, have long been recognized for their roles in response to neuronal damage and injury. SCGs have specifically been implicated in a new role involving the creation and persistence of chronic pain, which may involve hyperalgesia and other forms of spontaneous pain. SGCs have the ability to release cytokines and other bioactive molecules that transmit pain neuronally. Neurotrophins and
