The immune system plays a crucial role in protecting the body against pathogens. MGO and MGO-derived AGEs have been implicated in the development of insulin resistance, type 2 diabetes, and other inflammatory diseases. However, MGO may also have beneficial effects as a defense mechanism during infections and diseases.
The immune system plays an essential role in protecting the body against pathogens. Immune cells are activated during infections, resulting in a metabolic shift from oxidative phosphorylation to glycolysis. During glycolysis, methylglyoxal (MGO) can be formed as a by-product. As a highly reactive dicarbonyl compound, MGO can rapidly react with proteins to form advanced glycation end products (AGEs). MGO and MGO-derived AGEs have been implicated in the development of insulin resistance, type 2 diabetes and its complications and several other age-related inflammatory diseases. MGO has been found in adipose tissue, atherosclerosis plaques and inflamed livers. Aside from the potential harmful role of MGO, there are studies showing beneficial effects of MGO as a defense mechanism during infections and diseases. In this review, we summarize anti-microbial effects of MGO and the link between MGO and immune cell activation, as potential mediator during host defense.
