Compared to its parental virus, VSV-S not only increases apoptosis by overexpressing SMAC during VSV infection but also triggers elevated levels of PANoptosis (pyroptosis, apoptosis, and necroptosis) in HNSCC cells via activation of caspase-1/gasdermin D (GSDMD) signaling. This evidence concerns the gene CASP1 and head and neck squamous cell carcinoma.
