SLC1A3 and psychiatric disorder: Prevalent astrocyte markers (based on a variety of protein antibody positioning) in the brain tissue including GFAP, the water channel aquaporin‐4 (AQP4), the calcium‐binding protein, and the glutamatergic markers (including excitatory amino acid transporters 1 and 2 [EAAT1, EAAT2]) and glutamine synthetase, etc.175, 195There is evidence that each of these astrocyte markers is altered in psychiatric disorders.
