Influenza A virus (IAV) triggers multiple programmed cell death pathways, including MLKL-dependent necroptosis, caspase-8-dependent apoptosis, and caspase-1-dependent pyroptosis in myeloid cells. All three pathways share common upstream regulators, namely, ZBP1 and RIPK3. Yet, the molecular mechanism underlying IAV-induced inflammasome activation remains unclear. Here, we demonstrate that MLKL promotes inflammasome activation and IL-1β processing in IAV-infected macrophages. MLKL drives NLRP3 inflammasome activation through potassium efflux. In the absence of the MLKL-inflammasome axis, caspase-8 coordinates the maturation and secretion of IL-1β. MLKL alone is dispensable for host inflammatory responses to IAV in vivo. Taken together, MLKL and caspase-8 serve as redundant mechanisms by which to drive an inflammatory form of cell death in response to an IAV infection.
