表位联系是协作发起免疫反虚的一个重要机制,它可以使免疫反应针对某一抗原结构的各个表位而发生。在抗体形成中,表位联系由两型细胞簇—即T_H 细胞和B 细胞所介导,在Tc 细胞反应中,表位联系由T_H、Tcp(细胞毒性T 前身细胞)和APC 所组成的三型细胞簇所介导。这两类细胞簇都是通过粘着分子和局部分泌淋巴因子传递活化信号的,但是它们在抗原提呈细胞、淋巴因子及成簇的结构部位诸方面有所不同,因此有必要比较一下两者在针对相同抗原结构时的效
Epitope contact is an important mechanism for initiating immunodeficiency, which can make the immune response take place for each epitope of a certain antigen structure. In antibody formation, epitopes are mediated by two types of cell clusters, namely, T_H cells and B cells. In Tc cell responses, the epitopes associate with tH, Tcp (cytotoxic T precursor cells) and APC Type cell cluster mediated. Both cell clusters transmit activation signals through adhesion molecules and the local secretion of lymphokines, but they differ in terms of antigen presenting cells, lymphokines and clustered structural parts, so it is necessary to compare the two Effective against the same antigenic structure
