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
Perisynaptic schwann cells PSCs are based on both external synaptic properties and internal glial properties, where the internal characteristics of PSCs develop based on the associated synapse, for example: the PSCs of a fast-twitch muscle fiber differ from the PSCs of a slow-twitch muscle fiber even when removed from their natural synaptic environment. PSCs of fast-twitch muscle fibers have higher Calcium levels in response to synapse innervation when compared to slow-twitch PSCs. This balance between external and internal influences creates a range of PSCs that are present in the many Neuromuscular Junctions of the Peripheral Nervous System. Perisynaptic (Terminal) Schwann Cells were first
