Abstract
Membrane-active peptides are a large family endowed with a wide pattern of biological activities (antimicrobial, viral fusion and infection, cell-penetrating or protein-transduction domain), which share the property of interacting with membranes and being internalized in eukaryotic cells. Apart from pinocytosis internalization pathways, these peptides have the capacity to re-organize lipid membranes and to lead to membrane fusion, disruption or pore formation. In this chapter, we focus on these membrane perturbation processes evoked by cell-penetrating peptides that have been widely studied with membrane models and in cultured cells.
