glial fibrillary acidic protein

[MIM*137780]
a cytoskeletal protein of 51 kD found in fibrillary astrocytes; stains for this protein are frequently used to assist in the differential diagnosis of neurologic lesions.

GFAP

A gene on chromosome 17q21 that encodes a major class-III intermediate filament protein of mature astrocytes, which serves as a marker (in histopathology) to distinguish astrocytes from other glial cells, both during development and in tumour diagnostics.

Molecular pathology
Defects in GFAP are linked to Alexander disease.

gli·al fib·ril·la·ry a·cid·ic pro·tein

(glī'ăl fib'ri-lar-ē ă-sid'ik prō'tēn)
A cytoskeletal protein of 51 kD found in fibrous astrocytes; stains for this protein are frequently used to assist in the differential diagnosis of neurologic lesions.

glial fibrillary acidic protein

Abbreviation: GFAP
An intermediate filament found only in astrocytes and astroglial cells. It forms part of the skeletal structure of neurons. Abnormalities in GFAP are found in a variety of neurological diseases, including Alzheimer's disease, Creutzfeldt-Jakob disease, and some brain tumors.

In recent times there has been several studies [12, 13] regarding the role of complex biochemical markers of brain damage: such as S100B protein, neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP), apolipoprotein E (ApoE), tumor necrosis factor (TNF)-[alpha], soluble tumor necrosis factor receptor I (sTNFR-I), and interleukins (IL) and markers of oxidative stress, such as malondialdehyde (MDA) in aSAH patients.
