Abstract
⺠We investigate fluid phase coexistence effects on the membrane-restructuring properties of two HIV MPER-derived peptides. ⺠For NpreTM, fluid phase coexistence elicited vesicle fusion and “graded” membrane permeabilization. ⺠For CpreTM, fluid phase coexistence enhanced “all-or-none” leakage but did not promote fusion. ⺠Confocal microscopy of single vesicles revealed the preference of both peptides for liquid-disordered domains. ⺠We infer that MPER crowding into fluid nanodomains may boost its membrane-restructuring activity during HIV fusion.
