<i>Irg1</i> expression in myeloid cells prevents immunopathology during <i>M. tuberculosis</i> infection

Abstract excerpt

Immune-Responsive Gene 1 (Irg1) is a mitochondrial enzyme that produces itaconate under inflammatory conditions, principally in cells of myeloid lineage. Cell culture studies suggest that itaconate regulates inflammation through its inhibitory effects on cytokine and reactive oxygen species production. To evaluate the functions of Irg1 in vivo, we challenged wild-type (WT) and Irg1−/− mice with Mycobacterium...
