Abstract |
This study investigated the effect of aerobic exercise training on immune cell proliferation and inflammatory cytokine production in the spleen of high fat diet-induced obese mice. C57B1J6 male mice (4 weeks aged. n20) were fed a high fat diet (45% fat) for 5 weeks so that obesity was led intentionally. Then, these obese mice were divided into 2 groups: control group (CON. n10) or exercise group (EXE, n=l0). EXE performed treadmill running for 30-60 min/day at 10-22 m/min, 0% grade, five times per week for 8 weeks. After 13 weeks, all the splenocyte was collected and Con A (Concanvalin A 10 ㎍/ml) was used to stimulate the cell proliferation. MTS and BIOPLEX assay were used for cell proliferation and cytokine production. Independent t-test was used and a p-value under 0.05 was considered as statistically significant. In the results, body weight, IL-2 and IL-6 production were significantly reduced and Splenocyte proliferation was significantly increased after 8 weeks of exercise training. These findings suggest that aerobic exercise training has a positive effect for improving the obese-induced immune dysfunction. |
