Additionally, our study’s [19] finding of higher levels of IL-6, IL-10, and TNF-α in patients with MDD is consistent with the study by Sørensen et al. [20], which found that CSF levels of IL-4, MCP-1, and MIP-1 were higher in patients with recent-onset depression compared to healthy controls. The gene discussed is CCL2; the disease is major depressive disorder.
