Research up to now has tried but failed to decipher the cross-talk between 'killer T-cells' and' helper T-cells' in the fight against viruses.

在此之前的研究仍然未能明确“杀伤t细胞”和“辅助T细胞”在对抗病毒协同作用的机制。

Immunologists now recognize a four-point response system of helper t cells: Th 1, Th 2, Th 17 and regulatory t cells.

免疫学家现在认识到了辅助性T细胞(以下代号th)的四点反应系统：Th 1, Th 2, Th17和调节性T细胞。

The host cells in question are immune-system cells called T-cells. Specifically, they are "helper" T-cells, which orchestrate the immune system's response to pathogens such as viruses.

被选中的寄主细胞是一种被叫做T细胞的免疫系统细胞，具体而言，他们是辅助T细胞[注一]，它将应答免疫系统对例如病毒等病原体的反应。

The antigen has to be presented to helper T-cells, those helper T-cells have to stimulate a B-cell population to both proliferate and differentiate.

抗原需要被呈递给辅助性T细胞,这些辅助性T细胞需要激活B淋巴细胞,使其增殖和分化

Now, these Th-cells, helper T-cells, go on to stimulate B-cells, and it's these B-cells that become the mature antibody producing cells that make quantities of antibody that fill up in your body.

这些辅助性T细胞,进一步刺激B淋巴细胞,从而使这些B淋巴细胞,逐渐发育成成熟的抗体生成细胞,可在体内产生大量抗体

Helper cells don't become cytotoxic cells but they help B cells become antigen producing - antibody producing cells.

附助细胞不会成为细胞毒细胞,它们帮助B细胞成为抗体分泌细胞
