Fig. 8. Platelet pyroptosis exacerbates NETs and inflammation.

Fig. 8

Sepsis-derived S100A8/A9 induces GSDMD-dependent platelet pyroptosis via the TLR4/ROS/NLRP3/caspase 1/GSDMD pathway in severe sepsis. Pyroptotic platelets promote NET formation via ox-mtDNA, whereas NETs, in turn, lead to more platelet pyroptosis via release of S100A8/A9, forming a platelet pyroptosis–NET feedback loop.
