Abstract
The Krebs-cycle-derived metabolite itaconate has been shown to be immunomodulatory, targeting multiple processes in macrophages. Ramalho et al. reveal an additional role for itaconate in malaria.1Plasmodium Chabaudi induces itaconate in dendritic cells (DCs), leading to programmed death-ligand 1 (PD-L1) induction. This suppresses CD8+ T cells, important for host defense against malaria, thereby promoting parasitemia.
