Background: GFAP
An increase in GFAP levels is often associated with neuroinflammation which results in the activation and proliferation of astroglia cell population (1,2). GFAP expression is also observed in brains of patients with neurodegenerative diseases including Alzheimer's and Parkinson's, epilepsy disorders, and brain injuries (1-4). Lesion sites associated with neurodegeneration can exhibit an array of gliosis characteristics from glial scarring with reduced astrocyte proliferation to activated, GFAP-positive astrocytes surrounding amyloid plaques (2). Furthermore, the GFAP gene is a target of single nucleotide polymorphisms in the coding region, considered a gain-of-function mutation, characterized by astrocytic inclusions, termed Rosenthal fibers, resulting in Alexander Disease (1-4). GFAP is also a center of many post-translational modifications, such as phosphorylation, which can alter various aspects of filament assembly (1,4).
