Abstract

Receptor-interacting protein kinase 3 (RIP3/RIPK3) is a multifunctional regulator of cell death and inflammation. It controls signalling downstream of the tumor necrosis factor (TNF) receptor family, DNA-dependent activator of IFN-regulatory factors (DAI) and toll-like receptors (TLRs). Today, it is also widely recognized as a component of caspase-independent cell death known as necroptosis, and cytokine production via activation of the inflammasome. Its role in inflammasome activation, in particular, make the interpretation of its rolein vivomore complex. In this review, we focus on divergent roles for RIPK3 in cell death and inflammation.
