Immunity:青蛙粘液中含有可以帮助我们战胜流感的成分

2017-04-19 佚名 cnBeta

据外媒报道,一项最新的研发发现,一种色彩斑斓的青蛙中的粘液分子能够杀死一些流感毒株,并且可以为新的治疗提供有希望的途径。在《Immunity》杂志上发表的一项研究中,研究人员捕获了印度青蛙 Hydrophylax bahuvistara,并在轻微电击后收集了它们的皮肤分泌物。



据外媒报道,一项最新的研发发现,一种色彩斑斓的青蛙中的粘液分子能够杀死一些流感毒株,并且可以为新的治疗提供有希望的途径。在《Immunity》杂志上发表的一项研究中,研究人员捕获了印度青蛙 Hydrophylax bahuvistara,并在轻微电击后收集了它们的皮肤分泌物。



随后研究人员从分泌物中分离出几个分子,并在人类血液细胞上进行测试,随后他们发现一种能杀死流感病毒的 urumin 分子。最后,他们在小鼠身上进行测试,发现它们能够保护小鼠免受 H1 流感病毒的攻击。

青蛙粘液含有多肽类物质。在这项研究中,科学家首先筛选了 32 种针对各种流感病毒的青蛙多肽类物质,发现其中 4 种可以被用来打击病毒。但是当研究人员将这些多肽类物质放入含有红细胞的培养皿中时,其中三种杀死了血细胞。urumin 则是安全的,能够杀死流感病毒。通过使用电子显微镜,研究人员发现 urumin 通过与许多流感病毒中发现的蛋白质相互作用来完全破坏流感病毒。
