Of the cytokines directly induced by immune complexes, type I interferons, interleukin-18 (IL-18) and tumor necrosis factor (TNF) are correlated with inflammatory disease activity.
Altogether, these data reveal a new post-transcriptional role for USP47 and USP7 in inflammation by regulating inflammasome activation and the release of the pro-inflammatory cytokines IL-1β and IL-18, and implicate dual USP7 and USP47 inhibitors as potential therapeutic agents for inflammatory disease.
Caspase-1 promotes pyroptotic cell death and the maturation and secretion of interleukin (IL)-1β and IL-18, which trigger inflammatory responses to clear infections and initiate wound-healing; however, excessive responses cause inflammatory disease.
