Brief Summary

Depressive disorder is known as being accompanied with the activation of immune system which could lead to a series of changes including the neuron apoptosis, synapses transmission inhibition and emotional symptoms. The activation of protein kinase C (PKC) can reverse the immune/inflammatory process and restore the neuroplasticity and neurotransmitters transmission. Based on our finding that patients with major depressive disorder (MDD) showed a significantly lower gene expression of PRKCB1, while the PKC activation mediated by PRKCB1, we hypothesize that PRKCB1 contribute to the development of MDD and treatment response by its specific expression in brain, regulating ERBB, Chemokine signaling pathways and PKC activation during the neuroinflammatory process. In the present study, we aim to evaluate and verify the regulation effect of PRKCB1 on the neuroimmune and inflammatory mechanism in depressive disorder by a serious of studies focus on PRKCB1 gene expression modulating process and different downstream biomarkers which associated with PRKCB1 effect, combined with the specified treatment (plus omega-3 poly unsaturated fat acids). This study may provide scientific evidences for using neuroinflammatory biomarkers to diagnose MDD, as well as personalized treatment.
