The I245N and I245N/Q246Q mutant GSDMA were completely resistant to SpeB-mediated cleavage, while the Q246E mutant remained cleaved. Since GSDMA's broad protection in mammals improves mammals' ability to resist systemic infection, it will be interesting to investigate whether people with genetic variants in GSDMA are more susceptible to GAS infection.

Meanwhile, neither GSDMA alone nor SpeB alone could alter the morphology and viability of 293T cells lacking endogenous GSDMA, whereas co-expression of GSDMA with SpeB resulted in pyroptosis with balloon-like morphology and massive LDH release (Fig. 3c). (b). Quite recently, streptococcal pyrogenic exotoxin B (SpeB) was found to trigger keratinocyte pyroptosis by cleaving GSDMA after Gln246, resulting in the release of an active N-terminal fragment that induces pyroptosis.
