Role of cytokines in atypical depression

Abstract

Contrary to MD, AD has reversed vegetative symptoms, i.e. hypersomnia and hyperphagia. It is assumed that the phenotype difference between AD and MD might be related to Th1 cytokines (IL-2) and Th2 cytokines (IL-4) and not related to monocytic cytokines (IL-6, and TNF-α).
