SLC1A3 and schizophrenia: In schizophrenia, expression of EAAT1 and EAAT2 and their interacting proteins are altered in both the thalamus and cortex.8, 9, 10 EAAT1 and EAAT2 expression is generally found in glial cells.11 However, recent microscopy studies have expanded our understanding of the cellular localization of EAAT1 and EAAT2 in human brain.
