1·TLR2 is reported to enhance the expression of costimulatory molecules on the antigen presenting cell, however the regulatory mechanisms are still unclear.

已知tlr 2活化会促进抗原呈现细胞表面共同刺激分子的表现，但其调控机制及讯息传递路径仍不是非常清楚。

2·They are found in a perivascular network and may serve as the antigen presenting cell which initiates immune responses to antigens delivered through the circulation.

它们位于血管网周围，可以起到抗原递呈细胞的作用。抗原递呈细胞启动针对抗原的免疫反应并释放入血。

3·T cell can only recognize specific antigenic peptide-MHC complex on antigen-presenting cell. This is MHC restriction in antigen recognition of t cell.

细胞只能识别抗原提呈细胞表面特定的抗原肽MHC分子复合物，这就是T细胞抗原识别的MHC限制。

4·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。

5·After capturing tumor antigen, DC migrates to TDLN where it becomes matured and starts presenting antigen, then induces t cell differentiation, maturation and to kill tumor cells.

在捕获肿瘤抗原后，DC迁移至TDLN，发育成熟并递呈抗原，诱导T细胞分化、成熟，杀伤肿瘤细胞。

6·They are able to suppress allogenic T-cell response and modify maturation of antigen-presenting cells.

其能够抑制同种异体的T细胞的应答和修饰抗原呈递细胞的成熟。

7·Secondly, interactions between glycans and lectins play key roles in signal transduction, antigen presenting, control of cell development and differentiation.

其二，聚糖及其凝集素受体的相互作用在信号转导、抗原提呈、控制细胞发育与分化中起调控作用；
