The mechanisms of how obesity contributes to the development of cardio-metabolic
diseases are not entirely understood. Obesity is frequently associated with adipose tissue dysfunction,
characterized by, e.g., adipocyte hypertrophy, ectopic fat accumulation, immune cell infiltration,
and the altered secretion of adipokines. Factors secreted from adipose tissue may induce and/or
maintain a local and systemic low-grade activation of the innate immune system. Attraction of
macrophages into adipose tissue and altered crosstalk between macrophages, adipocytes, and other
cells of adipose tissue are symptoms of metabolic inflammation. Among several secreted factors
attracting immune cells to adipose tissue, chemotactic C-C motif chemokine ligand 2 (CCL2) (also
described as monocyte chemoattractant protein-1 (MCP-1)) has been shown to play a crucial role
in adipose tissue macrophage infiltration. In this review, we aimed to summarize and discuss the
current knowledge on CCL2 with a focus on its role in linking obesity to cardio-metabolic diseases.
