Furthermore, HIVEP2 mRNA levels were negatively correlated with mRNA levels for IL-1R, TNFR, NF-κB2, RelA, IFITM1, and IFITM2/3 (all r ≤ −0.24, all p ≤ 0.044), but not with cRel mRNA(r = −0.16, p = 0.18), across all subjects, but not in bipolar disorder subjects or comparison subjects alone (all r ≤ |0.32|, all p ≥ 0.065). Here, IFITM2 is linked to bipolar disorder.
