Gene expression of both MCP‐1 and F4/80 have been shown to be dramatically increased with obesity (Nickelson et al. 2012) but were significantly improved in the current report and were associated with reductions in some inflammatory gene responses (IL‐1β, TNFα, IL‐6) following 12 weeks of moderate treadmill training in HF‐fed animals. The gene discussed is IL1B; the disease is obesity disorder.
