Comparison of the effects induced by Chol depletion versus inclusion of peptides MPER(671–693) or MPER(671–693)L679I on the lateral organization of films made of the VL mixture. (A) AFM images were taken from VL mixture films compressed at the indicated surface pressures. Plots below images display the height profiles for the trajectories indicated by the white lines. AFM images were obtained at fixed Π = 10 mN/m. (B) Given here is the height difference between demixed domains and the surrounding lipid surface. Mann-Whitney test: ^∗∗∗p < 0.001, ^∗∗p < 0.01, ^∗p < 0.05, not significant (n.s.) ≥ 0.05. To see this figure in color, go online.
