1.And the same is true for the real hemagglutinin.

真正的血凝如此。机翻

2.To understand how this works, think of hemagglutinin as a bust of 19th century French Emperor Napoleon Bonaparte.

要了解其工作原理，请将血凝想象成 19 世纪法国皇帝拿破仑·波拿巴的半身像。机翻

3.On the inside is the virus' RNA, and on the outside are lots and lots of hemagglutinin proteins.

里面病毒的RNA，外面多多的血凝蛋白。机翻

4.The human flu virus could pick up a bird flu hemagglutinin that's never infected humans before.

人类流感病毒可吸收前从未感染过人类的禽流感血凝。机翻

5.And type A's can be divided into further sub-categories, depending on the subtypes of two proteins present on their surface: hemagglutinin, 'H', and neuraminidase, 'N'.

A型流感病毒还可步细分，取决于其表面存在的两种蛋白质的亚型：血凝(H)和神经氨酸苷酶(N)。

6.There are key parts of hemagglutinin that haven't changed much over time and are probably critical to infect human cells; these " conserved regions" could be promising targets for universal vaccines.

血凝的些关键部分随时间变化不大，可能对感染人体细胞至关重要；这些“保护区”可能成为通用疫苗的有前途的目标。机翻
