迫切需要开发新的抗病毒治疗方法;在目前可用的60种药物中,一半针对HIV-1,其余仅针对另外六种病毒。这种需求导致了可能的肽疗法的出现,目前有15种肽疗法正在进行临床试验。在理解天然存在的宿主防御肽的抗病毒潜力方面的进展突出了一类全新分子被认为是抗病毒治疗剂的潜力。阳离子宿主防御肽,如防御素和cathelicidins,是先天免疫的重要组成部分,具有抗微生物和免疫调节能力。近年来,它们也被证明是天然的、广谱的抗病毒药物,可对抗包膜和非包膜病毒,包括HIV-1、流感病毒、呼吸道合胞病毒和单纯疱疹病毒。在这里,我们回顾了这些宿主肽的几个家族的抗病毒特性及其潜在的通知新的治疗方法的设计。
There is a pressing need to develop new antiviral treatments; of the 60 drugs currently available, half are aimed at HIV-1 and the remainder target only a further six viruses. This demand has led to the emergence of possible peptide therapies, with 15 currently in clinical trials. Advancements in understanding the antiviral potential of naturally occurring host defence peptides highlights the potential of a whole new class of molecules to be considered as antiviral therapeutics. Cationic host defence peptides, such as defensins and cathelicidins, are important components of innate immunity with antimicrobial and immunomodulatory capabilities. In recent years they have also been shown to be natural, broad-spectrum antivirals against both enveloped and non-enveloped viruses, including HIV-1, influenza virus, respiratory syncytial virus and herpes simplex virus. Here we review the antiviral properties of several families of these host peptides and their potential to inform the design of novel therapeutics.
