NKCell—WhatIKnow.ppt NK Cell—What I Know 作者:刘学颖 范春秋 NK细胞的定义: NK细胞是一种大颗粒淋巴细胞,英文全称为natural killer cell,也称作自然杀伤细胞,它是一种能直接杀伤靶细胞效应的特殊的淋巴细胞系,具有抗肿瘤抗感染免疫调节的功能,且表现为速发效应。在医学上被称作是人体抵抗癌细胞和病毒感染...

Once the APC comes in contact with a T cell expressing the corresponding TCR, the antigen-MHC complex will bind to the TCR and initiate the signaling cascade. This alone is not sufficient to activate most naïve cells and can cause a cell to become anergic, or unable to carry out an im...
The existence of NKT-cell subsets, and other types of T cell that resemble NKT cells, is an ongoing source of confusion in the literature. This perspective article seeks to clarify which cells fall under the NKT-cell umbrella, and which might be best considered as separate....
HIV is very effectively transmitted during anal intercourse unprotected by condoms (UAI), with a meta-analysis finding that women may have an 18-fold greater HIV acquisition risk during UAI compared to vaginal intercourse unprotected by condoms (UVI) [1]. Thus, even a small proportion of interco...
Recent years have seen so-called natural killer T (NKT) cells emerge as important regulators of the immune response. The existence of NKT-cell subsets, and other types of T cell that resemble NKT cells, is an ongoing source of confusion in the literature
What is cell apoptosis, and how does it protect other cells around the infected cell? What are pluripotent cells? What are the T cells? What are the two big groups into which cells are classified? How do natural killer (NK) cells differ in function from CD8+ cells?
Through direct cytotoxicity or by the secretion of cytokines, NK cells also prevent overproliferation of precursor cell populations, thereby exerting a more discriminating control over antigen-specific T and B cell responses. The ultimate refinement of the killer cell is the cytotoxic T cell which ...
