NEUROG2 and post-traumatic stress disorder: As with PBMCs, gene set enrichment for psychiatric disorder gene sets27 revealed enrichment of HCort upregulated NGN2-neuron DEGs broadly across neuropsychiatric disorder risk genes, but not across PTSD-specific signatures (Fig. 2f), again suggesting that glucocorticoid treatment of NGN2-neurons, without considering PTSD diagnosis, is insufficient to recapitulate PTSD signatures.
