Consequently, here we simultaneously compared levels of GABA neuron subtype-selective transcripts (PV, KCNS3, SST, VIP, and CR mRNAs), as well as the pan-GABA neuron marker GAD67 mRNA, in the DLPFC from 160 individuals, including those with SZ, BD, or MD and unaffected comparison (UC) individuals (n = 40 in each group). Here, GAD1 is linked to Behcet disease.
