Although expression of the α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid receptor subunits, GluA1 and GluA2, was not significantly altered in the hippocampus, T1D mice exhibited increased GluA2 expression and a slight but nonsignificant increase in GluA1 expression in the cortex compared to nondiabetic mice. The gene discussed is GRIA2; the disease is type 1 diabetes mellitus.
