Cytotoxic T cells are CD8-postive T cells that are specialized for the direct killing of cells that are infected (particularly with viruses), cancerous or damaged in other ways. They express the glycoprotein CD8, as well as T cell receptors that recognize antigenic peptides presented by MHC cl...
百度试题 结果1 题目CTL(cytotoxic T lymphocyte) 相关知识点: 试题来源: 解析 CTL:即Tc,细胞毒性T细胞,也称杀伤性T细胞。表达CD8分子或CD4分子,主要功能是通过特异性识别靶细胞,释放穿孔素、颗粒酶或表达FasL而导致靶细胞裂解或凋亡。反馈 收藏
试题来源: 解析 细胞毒T淋巴细胞抗原-4cytotoxicTlymphocyteantigen-4,CTLA-4又称为CD152,为同源二聚体,表达于活化的T细胞上,其胞浆区可与磷酸酶SHP-1、SHIP结合,对T细胞具有负调节作用。它和CD28分子均能与CD80/CD86结合,共同调节免疫应答。反馈 收藏 ...
Cytotoxic T Lymphocy 一般情况下,循环和淋巴结驻留CD8 T细胞根据其分化状态细分为Naive T细胞、效应性T细胞和记忆性T细胞亚群。关于CD8 T细胞如何形成特异性,DP细胞通过与肽:MHC I类复合物的相互作用在胸腺皮质中进行阳性选择,生成CD8 SP细胞。随后这些SP细胞从皮质迁移到髓质,然后将在髓质中进行阴性克隆选择,以去除...
中文别名:Cytotoxic T-lymphocyte 4蛋白 来源:Mammalian cells 形态:Protein is supplied in 20 mM Tris,150 mM NaCl, 10% Glycerol, pH 7.5 储存/保存方法:Clear solution, frozen.Store at -70°C. At first use, aliquot and store at -70°C to avoid multiple freeze-thaws. ...
The meaning of CYTOTOXIC T CELL is a T cell that usually bears CD8 molecular markers on its surface and that functions in cell-mediated immunity by destroying a cell (such as a virus-infected cell) having a specific antigenic molecule displayed on its su
