1·If a helper cell recognises an antigen, it becomes activated.

如果某一个助细胞识别出一个抗原，该助细胞就会被活化。

2·Objective To investigate the changes of serum T helper cell (TH)1/TH2 type cytokines after the active immunotherapy in unexplained habitual abortion (UHA) women.

目的探讨原因不明习惯性流产（UHA）患者主动免疫治疗前后血清T辅助细胞（TH） 1/TH2型细胞因子的变化。

3·Profound immunologic changes occur during pregnancy, involving a polarization of t helper cells towards a dominance of Th2 and regulatory t cell effector responses in both mother and fetus.

意义深远的免疫性的改变发生在怀孕期间，对于在母亲和胎儿中多数的th2和调整的t细胞效应器都反映包括了th细胞的极化。

4·Sat-RNA of CMV is a subviral agent, which depends on its helper virus to replicate and cell to cell diffuse.

CMV 的 Sat-RNA 是一种亚病毒剂，取决于其辅助病毒的复制和细胞间的扩散。

5·Both helper (CD4) and cytotoxic (CD8) T-cell classes have been described.

现已明确两类T细胞：辅助性T细胞(CD4)和细胞毒性T细胞(CD8)。

6·Antibody production that is stimulated through increased helper T-cell function can activate complement.

通过增加辅助性T细胞的功能能够刺激抗体生成，活化补体。

7·The CD4 + test directly measures the abundance of the helper t cell, an of immune cell in the bloodstream distinguishable because they are the only ones that carry the CD4 marker.

CD 4 +试验直接检测辅助型T细胞数量。辅助型T细胞是血流中可分辨的免疫细胞中的一种，因为只有他们才具有CD 4标志物。

8·Like oTher viruses, HIV needs a hosT cell To mulTiply. IT aTTacks helper T cells and can infecT oTher cells.

像其它的病毒一样，HIV病毒也需要一个主体细胞来繁殖。它攻击辅助T细胞并感染其它的细胞。

9·Before a helper t cell can trigger a response to a pathogen or parasite, it has to feel these molecular bits of an invader displayed on the surface of an antigen-presenting cell (APC).

在辅助T细胞激发针对病原的免疫反应之前，它必须感觉到位于抗原递呈细胞面表的入侵者分子片段。

10·This review summarizes theory and method-ology of prediction for helper T cell epitopes, and their application in vaccine development against parasites, and new research directions are also discussed.

本文概述辅助T细胞表位预测的理论和方法及其在寄生虫疫苗研发中的应用，并讨论未来的研究方向。
