WebSep 21, 2024 · Recently, some studies have shown that immune responsive gene 1 (IRG1, also called ACOD1) was upregulated significantly by IFN-γ or LPS stimuli. 6 IRG1 is an enzyme that catalyzes the production of itaconate by decarboxylating cis-aconitate, which inhibits microorganism replication through itaconate and reactive oxygen species (ROS). … WebJun 2, 2024 · Citraconate inhibits ACOD1 (IRG1) catalysis, reduces interferon responses and oxidative stress, and modulates inflammation and cell metabolism Nature Metabolism …
Immune Responsive Gene 1 (IRG1) Promotes Endotoxin Tolerance …
WebIRG1 is a cis-aconitate decarboxylase that produces itaconic acid by decarboxylating cis-aconitic acid, an intermediate of the tricarboxylic acid cycle (4). Itaconic acid is an endogenous inhibitor of succinate dehydrogenase, linking macrophage metabolic rewiring and regulation of inflammation (5,6). Lee, C.G. et al. (1995) Immunogenetics 41 ... WebJul 12, 2016 · Itaconate production is one of the hallmarks of macrophage activation on both the transcriptional and metabolic levels: Irg1 is one of the most highly induced enzymes in activated macrophages, and itaconate … fisher x101d

WebInositol-requiring enzyme 1 (IRE1) is a bifunctional serine/threonine kinase and endoribonuclease that is a major mediator of the unfolded protein response (UPR) during endoplasmic reticulum (ER) stress. It represents a potential therapeutic target for a number of diseases associated with endoplasmic reticulum stress. WebMar 6, 2024 · Irg1 expression in myeloid cell subsets was necessary to control neutrophil recruitment, Mtb infection, and immune-mediated tissue injury. Our studies define a key role for Irg1 in regulating immune cell metabolism in subsets of myeloid cells, which minimizes the pathological immune response that contributes to pulmonary disease caused by Mtb. WebAs one of the most induced genes in activated macrophages, immune-responsive gene 1 (IRG1) encodes a mitochondrial metabolic enzyme catalysing the production of itaconic acid (ITA). Although ITA has an anti-inflammatory property, the underlying mechanisms are not fully understood. fisher x202b restoration
