Inflammation and depression: Mechanisms and involved molecules

Depression is a main complication in the developed and in developing countries. Studies showed that depression not only is a emotional disease but also affect the body. Immune system disordering is an important complication following depression. Studies showed that depression can induce immunological chronic inflammation، hence، lead to accelerate depression. Several molecules including JAK/STAT pathways and Toll like receptors، AIMII and NLRs play important roles in inducing chronic inflammation. It seems that the mentioned molecules can induce inflammation via cytokine production in depressed patients. Therefore، evaluation of cytokine patterns and cytokines producing pathways in depressed patients can help scientists to find the pathogenesis of depression. Thus، the aim of this review article was to collect recent information regarding cytokine patterns as well as the related molecules in inflammation in depression.
