Electroacupuncture combined with NSCs-Exo alters the response of hippocampal neurons in a chronic unpredictable mild stress paradigm in ovx rats.

Electroacupuncture (EA) is a form of Traditional Chinese Medicine (TCM) that combines acupuncture with microcurrents mimicking the body's bioelectricity to prevent and treat diseases. Previous studies have demonstrated its antidepressant-like effects in chronic unpredictable mild stress (CUMS)-induced ovariectomy (OVX) rats. Neural stem cell-derived exosomes (NSCs-Exo) are heterogeneous and targeted, effectively promoting nerve regeneration and repairing neuronal damage, while potentially conveying the effects of EA.
