- Although many individuals may share some identical MHC molecules, a very low number share all the MHC molecules. 尽管很多人会有一些相同的MHC分子,极少数人有完全相同的MHC分子。
- In most cases, the T cells ignore MHC molecules that display fragments of protein from the body's own cells. 在大多数情况下,T细胞对显示含有自身细胞来源的片段的MHC分子没有反应。
- Class II MHC molecules are found on the APCs of the immune system, which are B cells, monocytes or macrophages, and DCs. 医学的集成化趋势,所谓医学的集成化是指医学研究中出现的将众多相关学科集于一个研究领域,形成新的学科技术的发展趋势。
- Females use smell to identify partners with suitable MHC molecules: choosing only males with the correct mix of immune genes critical for the survival of future offspring. 分子的伴侣,这样一来,它仅仅选择那些对后代的存活至关重要的、具有正确免疫基因组合的雄性动物。
- The binding of antigenic peptide sequences to major histocompatibility complex(MHC) molecules is a prerequisite for stimulation of cytotoxic T cell responses. 抗原多肽序列与主要组织相容性复合体(MHC)分子的结合是引起T细胞免疫应答的先决条件。
- Many scientists suspected that although the shape of MHC molecules varies between individuals, they might share some similarity that T cells receptors could recognize. 许多科学家推测尽管两个体间MHC分子形状差异,他们也许共同拥有为T细胞识别的一些类似之处。
- Once at their destinations, the cells complete their maturation and present their antigen-laden MHC molecules to naive helper T cells, those that have never encountered antigens before. 到达目的地之后,树突细胞也成熟了,并将满载抗原的MHC分子呈现给从未接触过这些抗原的辅助者T细胞。
- Although the structure of CD1 molecules is very similar to that of MHC molecules,there are essential differences in the biochemical character and physical structure of antigens recognized by them. 不仅CD1分子与MHC分子抗原识别机制不同,而且CD1家族内部各分子之间在识别脂类抗原时也有区别。
- Adhesive molecule,MHC molecule,Fas and Fas ligand expression were found to be increased in sympathetic ophthalmia eyes. 另外 ,局部还存在黏附分子、MHC和fasL等免疫相关分子的表达增加。
- The first signal is specific, which T cell receptor could recognize and bind MHC molecule by antigen presenting cells. 第二信号是由T细胞上的CD28与抗原呈递细胞上的B7分子的结合而提供的。
- Donor-reactive CD8 memory T-cell infiltration, proliferation and ICOS expression are regulated by donor class I MHC molecule expression. 供者MHC-I类分子的表达能够调节供者反应性CD8记忆T细胞浸润、增殖以及ICOS的表达。
- But when they detect an MHC molecule carrying a protein fragment from a bacterium, irus, or other inader, the T cells launch an attack. 但检测到带有来自细菌、病毒或其它入侵者蛋白片段MHC分子时,T细胞就会群起而攻之。
- Objective To study the model of the quantitative structure-activity relationship (QSAR) CTL epitopes binding to MHC molecule. 目的研究了CTL表位与MHC分子结合的定量构效关系模型。
- If the Tc cell “sees” an antigen in conjunction with a MHC molecule of a different allotype (from a different person), it will not be able to recognize and destruct. 我们认真对待每一次的翻译,严格执行相关国家标准和公司内部质量管理规范,赢得了众多客户的好评和良好的市场信誉。
- Some biological molecules have the form of a helix. 有些生物分子呈螺旋状。
- A chemical compound consisting of such molecules. 二聚化合物这种聚合物形成化合物
- Containing molecules consisting of two fused rings. 二环的包含由两个结合的环组成的分子的
