| abstractText | Necroptosis is a recently defined type of programmed cell death with the specific signaling cascade of receptor-interacting protein 1 (RIPK1) and RIPK3 complex to activate the executor MLKL. However, the pathophysiological roles of necroptosis are largely unexplored. Here, we report that fungus triggers myeloid cell necroptosis and this type of cell death contributes to host defense against the pathogen infection. Candida albicans as well as its sensor Dectin-1 activation strongly induced necroptosis in myeloid cells through the RIPK1-RIPK3-MLKL cascade. CARD9, a key adaptor in Dectin-1 signaling, was identified to bridge the RIPK1 and RIPK3 complex-mediated necroptosis pathway. RIPK1 and RIPK3 also potentiated Dectin-1-induced MLKL-independent inflammatory response. Both the MLKL-dependent and MLKL-independent pathways were required for host defense against C. albicans infection. Thus, our study demonstrates a new type of host defense system against fungal infection. |
