Depression and immune function

Major depression is often associated or correlated with immune function dysregulation, and the two are thought to share similar physiological pathways and risk factors. Primarily seen through increased inflammation, this relationship is bidirectional with depression often resulting in increased immune response and illness resulting in prolonged sadness and lack of activity. This association is seen both long-term and short-term, with the presence of one often being accompanied by the other and both inflammation and depression often being co-morbid with other conditions.
