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
Nasal glial heterotopia there is a large amount of associated fibrosis. The lesions are usually <2 cm in greatest dimension. A trichrome stain will highlight the dual components well, with the glial tissue staining red, while the background fibrosis stains a bright blue. The glial tissue is highlighted with S100 protein and with glial fibrillary acidic protein, although the latter is much more sensitive for glial tissue. The most common missed lesion is within the nasal cavity, where a fibrosed nasal polyp may be considered. However, it does not have glial tissue. Further, a polyp usually has mucoserous glands. The lesion is frequently
