The roles of the mtDNA-cGAS-STING axis in tumor immunity: from immune activation to immune evasion

In the tumor microenvironment (TME), stress-induced mitochondrial DNA (mtDNA) leakage activates the mtDNA-cyclic GMP-AMP synthase (cGAS)- stimulator of interferon genes (STING) axis, which exerts a “double-edged sword” role in tumor immunity. On the one hand, it activates the STING- interferon regul...
