Metabolic crosstalk in the regulation of inflammation

The study of the molecular basis to the immune response has for decades concerned receptors and the signalling pathways they activate which lead to immune cell activation. Recently metabolic changes have also been shown to couple to immune effector responses. A shift in appreciation of the role of metabolites beyond energy metabolism and biosynthetic processes has emerged. We have been examining the role of three metabolites in macrophages. We have evidence that two of these, malonyl-CoA and 2-hydroxyglutarate (2-HG) are pro-inflammatory, whilst the third, itaconate, has profound anti-inflammatory effects. In many ways, they mirror cytokines, with malonyl-CoA and 2-HG being akin to…
