[Research progress on receptor interacting proteins in inflammation].

Receptor interacting proteins (RIPs) are a group of threonine/serine protein kinases, which have relatively conserved kinase domains and different non-kinase domains, and are involved in physiological and pathological processes including innate immune response and inflammation. In recent years, many studies have shown that RIPs mediate cell necroptosis and triggers inflammatory responses by participating in the formation of necrotic complexes, and RIP1 and RIP3 are particularly closely related to cell necrosis. Cell necroptosis is a well-regulated way of cell death. The death signal that transmit through the TNF signaling pathway and the Toll-like receptor signaling pathway can recruit and phosphorylate mixed lineage kinase domain-like protein (MLKL), and eventually leading to disintegration and death of cells, and the release of cells intercellular material after cell disintegration can trigger an inflammatory reaction. This review mainly focuses on the major signaling pathways and molecular mechanisms that are involved in the mediation of necrosis and inflammation by RIPs. It also highlights the importance of RIPs in the development of inflammatory diseases and their potentials as therapeutic targets for inflammatory diseases.
