Membrane-Membrane Interactions via Intermediates in Lamellar-to-Inverted Hexagonal Phase Transitions

  • Chapter
Cell Fusion

Abstract

Recent theoretical work (Siegel, 1984, 1986a-c)shows that vesicles whose lipids can undergo the Lα/HII(lamellar-to-inverted hexagonal) phase transition should be especially susceptible to three membrane-membrane interactions: fusion, aggregation-induced vesicle leakage, and intervesicular lipid exchange. This chapter describes this model as well as experimental results derived from relevant systems. The model shows that in HII-forming systems the relative rates of the three membrane-membrane interactions may be determined by the lipid-phase behavior and the dynamics of the Lα/HIIphase transition, i.e., the rate at which A. given lipid system can execute the Lα/HIIphase transition under given conditions.
