Necroptosis, a programmed form of lytic cell death, is initiated by various viral and bacterial pathogens through irreparable ion dysregulation and energy depletion. This cellular damage results in the activation of the cellular kinases RIPK1 and RIPK3, consecutively, and the activation and membrane targeting of MLKL, the latter responsible for lysis. Here we have demonstrated that necroptosis of airway epithelial cells is key in the development of the adaptive immune response to asymptomatic colonization by Streptococcus pneumoniae (Spn). Briefly, necroptotic deficient animals or wildtype animals colonized with Spn lacking the necroptosis-triggering pneumolysin toxin, failed to recruit CD11c+ leukocytes to the …
