Macrophage respiratory complex III governs immune evasion.

Abstract

The intricate interplay between cellular metabolism and immune function has emerged as a pivotal area of research in immunology. Macrophages, as central players in the innate immune system, exhibit remarkable metabolic flexibility that influences their activation states and functional outputs, with important implications for the pathophysiology of inflammatory diseases and cancer. A recent study by Zotta and colleagues provides new insights into the role of mitochondrial complex III (CIII) in regulating the anti-inflammatory cytokine interleukin-10 (IL-10) and its implications for tumor immunity.
