Abstract

Depression is a debilitating mental illness and is often comorbidwith metabolic disorders such as type 2 diabetes. Adiponectin is an adipocyte-derived hormone with antidiabetic and insulin-sensitizing properties. Here we show that adiponectin levels in plasma are reduced in a chronic social-defeat stress model of depression, which correlates with decreased social interaction time. A reduction in adiponectin levels caused by haploinsufficiency results in increased susceptibility to social aversion, "anhedonia," and learned helplessness and causes impaired glucocorticoid-mediated negative feedback on the hypothalamic-pituitary-adrenal (HPA) axis. Intracerebroventricular (i.c.v.) injection of an adiponectin neutralizing antibody precipitates stress-induced depressive-like behavior. Conversely, i.c.v. administration of exogenous adiponectin produces antidepressant-like behavioral effects in normal-weight mice and in diet-induced obese diabetic mice. Taken together, these results suggest a critical role of adiponectin in depressive-like behaviors and point to a potential innovative therapeutic approach for depressive disorders.
