Polygalic acid produces rapid antidepressant effects via modulation of hippocampal inflammation and brain-derived neurotrophic factor expression in mice.
Major depressive disorder represents a critical global health burden with limited rapid-acting therapeutic options. This study investigated the natural triterpenoid saponin polygalic acid for rapid antidepressant efficacy and its mechanistic relationship with neuroinflammation. In male C57BL/6 mice subjected to chronic...
