Cooling inflammation through metabolism with 4-octyl itaconate
Itaconate is an immunomodulatory metabolite that links metabolism and inflammation. Li et al. uncover a mechanism by which itaconate and 4-octyl itaconate suppress cytokine signaling through the alkylation of tyrosine kinase 2 and Janus kinase 1. This study reveals a direct metabolic control of inflammation and highlights its therapeutic potential in sepsis.
