Balance of immune responses in the regulation of adipose tissue function. Lean adipose tissue harbors various anti-inflammatory immune cells, such as eosinophils, M2 macrophages, Th2 cells, iNKT cells, and Treg cells. These immune cells help in maintaining insulin sensitivity and store extra energy in the form of TGs. In obese adipose tissue, the numbers of pro-inflammatory immune cells, including neutrophils, M1 macrophages, mast cells, Th1 cells, and CD8 T cells, are greatly elevated. Simultaneously reduced number of anti-inflammatory immune cells accelerates pro-inflammatory response and adipose tissue dysfunction.
