Depression induce by chronic neuroinflammation disrupts daily life and work, underscoring the importance of its treatment. It this study, depressive- and anxiety-like behaviors were induced in mice by injecting bacillus Calmette-Guérin (BCG), resulting from chronic neuroinflammation. Daily stimulation with specific acupuncture points (Baihui and Yintang, GV20 and GV29) with electroacupuncture (EA) for 14 days significantly alleviated depressive- and anxiety-like behaviors. Additionally, it also markedly reduced the levels of pro-inflammatory cytokines, including interleukin (IL)-6, IL-1β, and tumor necrosis factor-α, as well as inflammatory markers such as cyclooxygenase-2, in both the plasma and hippocampus. EA Stimulation significantly increased brain-derived neurotrophic factor (BDNF) mRNA expression in the hippocampus. Our results demonstrated that EA stimulation improved depression- and anxiety-like behaviors induced by chronic inflammation, an effect associated with the decreased expression of BDNF via regulation of NF-κB pathway.
