Antidepressant Effects of Exercise: A Role for the Adiponectin‐PGC‐1α‐kynurenine Triad?

It is well-recognized that exercise improves mental health, e.g., by decreasing depressive behaviors, improving hippocampal-dependent learning and neurogenesis, and increasing dendritic plasticity. Yet how exercise influences the brain at the molecular level is not clearly understood. Yau et al recently reported that the antidepressant effects of physical exercise are mainly mediated by adiponectin, an adipocyte-secreted hormone ('adipocytokine') with neuroprotective effects at the central nervous system level (Yau et al., 2014).4.155 JCR (2015) Q1, 12/83 Physiology; Q2, 63/187 Cell biologyUE
