In this study, we assessed the mRNA levels of TNFAIP3, TNFAIP3-interacting proteins (TNIP), including TNIP1, TNIP2, and TNIP3, and TNFAIP3-like proteins, such as cezanne1, cezanne2, trabid, and VCIP135, in TNF-α-secreting cells and examined their association with severity of depression using the 17-item Hamilton Depression Rating Scale (HAMD-17) scores from 30 MDD patients and 30 healthy controls.
Multiple linear regression analyses revealed that TNFAIP3 mRNA expression before treatment was inversely correlated with severity of depression and effectively predicted improvement in HAMD-17 scores.
