In addition to adipocyte-derived factors, an increased release of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and additional products of macrophages and other cells that populate adipose tissue also play a role in the development of cardiovascular and metabolic risk including insulin resistance [107]. The gene discussed is CCL2; the disease is Insulin resistance.
