The results indicated that acupuncture significantly reduced the expressions of pro-inflammatory cytokines which included IL-1β [SMD = −3.50, 95% CI (−4.31, −2.69); I2 = 78.6%] (P < 0.05), TNF-α [SMD = −3.05, 95% CI (−3.86, −2.24); I2 = 69.6%] (P < 0.05), IL-6 [SMD = −3.22, 95% CI (−4.62, −1.81); I2 = 77.6%] and enhanced the expressions of anti-inflammatory cytokines including IL-4 [SMD = 2.77, 95% CI (1.95, 3.59); I2 = 33.9%] (P < 0.05), IL-10 [SMD = 1.84, 95% CI (1.20, 2.49); I2 = 41.0%] (P < 0.05) in an animal model of AD. This evidence concerns the gene IL10 and Alzheimer disease.
