RIPK3 is believed to contribute to lung inflammation and injury during severe infections with the influenza A virus.The experimental RIPK3 inhibitor UH15-38 has shown potential in preclinical studies to reduce mortality and lung damage in mice infected with influenza, indicating that RIPK3 may serve as a therapeutic target for managing hyper-inflammatory conditions such as influenza-related ...
The signaling pathway responsible for carrying out necroptosis is generally understood. TNFα leads to stimulation of its receptor TNFR1. TNFR1 binding protein TNFR-associated death protein TRADD and TNF receptor-associated factor 2 TRAF2 signals to RIPK1 which recruits RIPK3 forming the necrosome also named ripoptosome. [2]

UH15-38 targets and inhibits RIPK3, a key enzyme involved in necroptosis, a form of programmed cell death that can lead to excessive inflammation when left unchecked during severe influenza infections. By inhibiting RIPK3, UH15-38 appears to allow the immune system to effectively combat the virus while minimizing excessive cellular death and ...
Unlike the necroptotic pathway, this pathway doesn't include the inhibition of caspase-8. Thus, in absence of NF-κB function, FLIP is not produced, and therefore active caspase-8 assembles with FADD, RIPK1 and RIPK3 in the cytosol, forming what is known as complex IIa. [20]

PANoptosis is a prominent innate immune, inflammatory, and lytic cell death pathway initiated by innate immune sensors and driven by caspases and receptor-interacting protein kinases (RIPKs) through multiprotein PANoptosome complexes.
Apart from apoptosis, Wang also discovered the necroptosis pathway, which is the programmed form of necrosis and another way that a cell kills itself. He established the role of RIPK3 and the MLKL protein in necroptosis. [20]
