Abstract:

Antimicrobial peptides (AMPs) consist of a diverse group of small molecular polypeptides that widely exist in organisms and act as an important part of the innate immune system. AMPs can not only effectively kill bacteria, but also kill fungi, viruses, parasites and even tumor cells. It has been proved that antimicrobial peptides can inhibit the growth of different stages of Plasmodium protozoan and no drug tolerance has been identified so far, making it valuable as a novel anti-malaria agent. Currently, a variety of AMPs with anti-malarial activities have been successively isolated and identified. It includes the AMPs that target Plasmodium within erythrocytes such as dermaseptins and their derivatives dermaseptin S3 and dermaseptin S4, cecropin B and its derivatives SB-37 and Shiva-1, Defensin DefMT2, DefMT3 and DefMT5, etc. Those AMPs targeting the sexual stage of Plasmodium mainly include duramycin, melittin, TP10 and Vida1-Vida3. In this paper, the inhibition effects of AMPs on different developmental stages of Plasmodium and the possible mechanisms are reviewed.
