APIP regulates the priming of canonical NLRP3 and non-canonical Caspase-11/4 inflammasomes by binding to TRAF6
APIP (Apaf-1-interacting protein) plays a pivotal role in regulating inflammasome activity, particularly the NLRP3 and caspase-11 pathways, which are critical in inflammatory responses. This study demonstrates that APIP enhances the activation of these inflammasomes by binding to TRAF6, thereby promoting systemic inflammation. The findings suggest that targeting APIP could be a promising therapeutic strategy for treating inflammatory diseases such as sepsis, highlighting its potential as a valuable investment opportunity in the biotechnology sector.
