We clarify that IpaH7.8 targets human (but not mouse) GSDMD through a similar mechanism. The structure of full-length GSDMB suggests stronger autoinhibition than in other gasdermins 9,10 .
Several polymorphs of MnO 2 are claimed, as well as a hydrated form. Like many other dioxides, MnO 2 crystallizes in the rutile crystal structure (this polymorph is called pyrolusite or β-MnO 2), with three-coordinate oxide and octahedral metal centres.
