Abstract

Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) is an antibody-related astrocytic disease for which a specific GFAP antibody serves as a biological marker. Indeed, cerebral spinal fluid positive and/or seropositivity for GFAP is an important basis for its diagnosis. However, because patients with autoimmune encephalitis or demyelinating diseases can have a similar antibody profile, termed overlapping autoimmune syndrome, it remains a challenge for clinicians to diagnose and suitably classify autoimmune GFAP-A. To further understand the significance of GFAP antibody detection in neuroimmune diseases, this article discusses GFAP antibodies in autoimmune GFAP-A, progress for detection of GFAP antibodies, diagnostic significance of GFAP antibodies in prototypical disease, as well as overlapping syndrome.
