of these AMPs against L. mexicana amastigotes was low. This suggests that amastigotes from different Leishmania species display varying susceptibility to peptides from the temporin family, perhaps indicating differences in their surface structure, the proposed target of these AMPs. In contrast, insect stage L. mexicana promastigotes were sensitive to two of the screened temporins which clearly demonstrates
鉴于利什曼病可用药物的缺乏和毒性,再加上耐药性的出现,发现这种被忽视的热带疾病的新疗法被认为是当务之急。因此,抗菌肽 (AMPs) 已被提议作为对抗致病利什曼原虫、昆虫媒介传播的原生动物寄生虫的有前景的化合物。在这里,AMP temporins A、B 和 1Sa 已被合成并筛选出对抗Leishmania mexicana昆虫阶段前鞭毛体和哺乳动物阶段无鞭毛体的活性,这是人类皮肤病的重要原因。与之前对其他物种的研究相比,这些 AMP 对L. mexicana的活性无鞭毛体低。这表明来自不同利什曼原虫物种的无鞭毛体对 temporin 家族的肽表现出不同的敏感性,这可能表明它们的表面结构存在差异,这些 AMP 的拟议目标。相比之下,昆虫阶段L. mexicana promastigotes 对两种筛选的 temporins 敏感,这清楚地证明了针对两种形式的寄生虫筛选 AMP 的重要性。版权所有
