Abstract

Background: Major depressive disorder (MDD) is a severe mental illness associated with severe clinical consequences and substantial societal burden. It's characterized by immune-inflammatory dysregulation and immune sensitization.

Methods: Whole blood from 18 patients with MDD and 18 HCs was stimulated with PH
