th cell meaning in Chinese
th细胞辅助性t细胞
Examples
- Igg , igm , iga are produced by b cell , in the course of b cell ' s activation , it needs nk c ell ' s assistant . before thymus transplantation , the patient associated with tumor has fewer th cell and its function recedes , so b cell ' s activation was suffocated and the ability of producing ig was weak
Igg ， igm ， iga由b细胞产生，而b细胞在活化的过程中，需要th细胞的辅助，胸腺移植前，由于癌症患者th细胞数量减少，功能低下，致使b细胞活化受阻，产生ig的能力低下。 - This modification includes : ( 1 ) selecting two important molecules as candidates , ( 2 ) choosing a promiscuous t - cell epitope , and two b - cell epitopes or conserved amino acid sequences from the two important molecules , ( 3 ) connecting them adequately through analysis by the molecule designing software . therefore , the synthetic new antigen may interfere with the process of fertilization by multiple ways and its contraceptive effects may be enhancing . based on the molecule designing methods , the b - lymphocyte cell epitope of sperm / testis specific protein sp17 and cyritestin which interfere with fertilization in mouse , as well as the promiscuous th cell epitope of the ribonuclease ( rnase ) in bovine were selected
本研究以蛋白质分子设计的理论和方法研究避孕疫苗，将sp17和cyritestin关键表位和牛核糖核酸酶非选择性th细胞表位合理组合，获得新抗原- 35肽序列；并在合成、纯化后分别与弗氏佐剂、免疫刺激复合物( iscoms )混合后免疫不同遗传背景的雌性小鼠，观察血清和生殖道内的特异性抗体滴度的动态变化、生育力的改变以及免疫后小鼠重要脏器的组织病理学改变：以及在ivf下，新抗原的特异性抗血清对精卵相互作用的影响及抗原在精子表面的特异性定位。
