Direct visualization of native GSDMD pores reveals lipid-driven stabilization during pyroptosis

PI(3,4,5)P3 lipid remodeling during pyroptotic cell death structurally stabilizes GSDMD pores at the plasma membrane.

Played around a bit with Blender over the weekend and made a movie of a computational assay I had set up a while ago. Gasdermin-D binds to PIP lipids and I wanted to know what impact it has to just populate the most prominent binding site. PIP3, even more than PIP2, stabilizes GSDMD oligomers!
