PLOS Neglect Trop D:科学家发现蚊虫叮咬会引起人体不寻常的免疫反应

2018-05-21 佚名 中国新闻网

据外媒报道,美国贝勒医学院(Baylor College of Medicine)的科学家发现,蚊虫叮咬会引起人体内一系列不寻常的免疫反应。

据外媒报道,美国贝勒医学院(Baylor College of Medicine)的科学家发现,蚊虫叮咬会引起人体内一系列不寻常的免疫反应。

据学术期刊《PLOS Neglected Tropical Diseases》报道,为进行试验,实验用的小鼠体内被植入了人体干细胞,人体免疫系统的各个组成部分就是从这些细胞发育而来。

接下来,研究人员允许四只蚊子尽情地叮咬小鼠。此后,在试验后6小时、1天和7天内,对小鼠提取了血液和身体其它组织的样本。

将这些样本和“未被叮咬”的小鼠的相关指标进行比较,研究人员发现,在被咬的小鼠体内。负责机体免疫反应的细胞因子的活性被激活。

此外,参与抗病毒和过敏反应的辅助T细胞也受到影响。与此同时,叮咬的影响保持长达7天,并触及到了机体的各种组织,包括血液、皮肤和骨髓等。

科学家们认为,这项研究可以帮助预防各种疾病的传播。
