RIPK3 and influenza: Even following viral infections with influenza [50,51] or SARS-CoV-2 [52], proinflammatory cytokines such as TNF and IFN-γ can also induce necroptosis [53,54,55] or PANoptosis [52] via other caspases and kinases such as the Receptor-Interacting Serine/Threonine Kinase 3 (RIPK3) [50,51] and Casp-8 [55].
