925-Mitochondrial Metabolism Fuels Anti-cancer cDCs

This study identifies mitochondrial metabolism as a primary regulator of the immune activation of conventional dendritic cells, specifically the cDC1 subtype. While previous models suggested that oxidative phosphorylation was linked to immune tolerance, this research demonstrates that an active electron transport chain (ETC) is actually required for cDC1s to rapidly respond to stimuli and prime T cells for anti-cancer immunity. Mechanistically, electron flow maintains a critical balance of metabolites and redox states that shapes the epigenetic landscape of the cell. Specifically, ETC…
