Our results indicated that 6 weeks of CUMS exposure induced significant depression-like behavior, with low 5-HT and NE levels, high TNF-α and IL-6 in brain and high hippocampal TNF-α, IL-6, P-NF-κBP65, and 5-HT2AR levels, and low BDNF expression levels. The gene discussed is NFASC; the disease is depressive disorder.
