根据发表在《Nature Medicine》上的研究报告，英国科学家声称发现了研发通用流感疫苗的"蓝图"。研究人员在2009年甲型H1N1流感流行之际，对300余名志愿者进行了跟踪研究，分析了免疫系统对新型流感病毒的反应。结果发现，在那些没有出现显著症状的志愿者血液内，一种名为"CD8 T细胞"的免疫细胞含量普遍较高。免疫系统应对季节性流感而产生了更多的CD8 T细胞，不同于抗体，这些细胞针对的是病毒不会发生改变的核心部分，因此对于未来的新流感变种也有效。研究人员认为，这一发现有助于未来开发出对普通季节性流感和新型流感等各种流感病毒均有效的广谱疫苗。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
