Depression is a common and recurrent mental disease, with complex etiology, which is mainly affected by genetic, metabolic and social factors. The specific pathogenesis is still unclear. In recent years, the hypothesis of inflammatory factors related to depression has attracted wide attention of researchers. A large number of clinical experimental studies have shown that depression is related to the increase of proinflammatory factors in central and peripheral blood. The inflammatory factors in peripheral blood can spread in the brain through the way of specific transporters across the blood-brain barrier, and activate or participate in the brain inflammatory response, and ultimately affect the neuronal activity and neurotransmitter release in the emotional regulation area of the brain, which in turn leads to depressive symptoms. This paper summarizes the relationship between inflammatory factors and depression and its possible mechanism, which provides reference for further prevention and control, clinical treatment and scientific research of depression.
