| Abstract |
Necroptosis, a form of regulated necrosis, is triggered by a variety of signals that converge to activate receptor interacting protein kinase-3 (RIPK3), consequently promoting the direct phosphorylation and activation of the mixed lineage kinase like (MLKL) protein. Active MLKL executes necroptosis by disrupting the integrity of the plasma membrane. Stimuli that can induce necroptosis include ligation of death receptors (a subset of the TNFR family), toll-like receptors (in particular, TLR3 and TLR4), interferons, and the intracellular viral sensor, DAI/ZBP1, among others. To study the process in more detail, it is useful to have a means to directly activate RIPK3. Here we provide protocols and procedures to artificially induce necroptotic cell death by drug-induced forced dimerization of RIPK3. We also provide information on specific kinase inhibitors, procedures to monitor RIPK3 and MLKL activation, and real-time quantification of cell death. |
