Obesity is associated with WAT inflammation, which is characterized by an increased infiltration of macrophages and elevated secretion of several cytokines and chemokines from both macrophages and adipocytes, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and monocyte chemotactic protein-1 (MCP-1) [40]. Here, CCL2 is linked to obesity disorder.
