Nitric oxide controls the immunopathology of tuberculosis by inhibiting NLRP3 inflammasome–dependent processing of IL-1β

Abstract: Interleukin-1 (IL-1) is an important mediator of innate immunity, but can also promote inflammatory tissue damage. During chronic infections, such as tuberculosis, the beneficial antimicrobial role of IL-1 must be balanced with the need to prevent immunopathology. By exogenously controlling the replication of Mycobacterium tuberculosis in vivo, we obviated the requirement for antimicrobial immunity and discovered that both IL-1 production and infection-induced immunopathology were suppressed by lymphocyte-deri… Show more

“…In actual bacterial infections, NO suppresses the activation of the NLRP3 inflammasome and the production of mature IL-1b in M. tuberculosis infection. NO-mediated inhibition of NLRP3 inflammasome activation resulted in the suppression of persistent neutrophil recruitment and progressive tissue damage in M. tuberculosis infection (Mishra et al 2013). In contrast, phosphorylation by downstream kinases including Syk and c-jun N-terminal kinase has recently been shown to regulate ASC (Hara et al 2013), and phosphorylated ASCinduced NLRP3 inflammasome activation.…”

“…La sécrétion autocrine/paracrine d'IFN-I conduit à la production de NO, en activant l'iNOS (inducible nitric oxyde synthase) responsable de la S-nitrosylation de NLRP3 au niveau de son domaine LRR riche en cystéines, qui inhibe l'assemblage de l'inflammasome [22]. L'IFN-(un interféron de type II) inhibe aussi NLRP3, par le même mécanisme [52].…”

“…Further, IFN-g enhances Th1 cell development. Despite those clearly proinflammatory features, IFN-g was described to suppress the generation of activeg-induced NO was demonstrated in both cases (22,24). Because NO production occurs with delayed kinetics (25)(26)(27), these effects were observed most prominently after long-term stimulation.…”
