B-E. High-resolution AFM topographs and height profiles of GSDMDNterm oligomers (red curves). Height profiles were measured along the red lines in the topographs. Dashed zero lines (0 nm) indicate the surface of the lipid membrane; heights of <−4 nm indicate that the oligomers formed transmembrane pores. Topographs were taken in buffer solution (150 NaCl, 20 mM Hepes, pH 7.8) at room temperature. The experiment was reproduced at least three times using independent liposome and GSDMD preparations.
