Development and mechanistic characterisation of membrane-active anticancer peptides

Organisms are well known to produce their own antibiotic host-defence peptides that act through damaging bacterial membranes due to their different molecular composition compared to the host organism’s own cells. Some of these antimicrobial peptides are also known to have anticancer properties. One particularly promising anticancer peptide is polybia MP1 (MP1) from the venom of […]
