This can be done in two ways. These pathways are the cytotoxic protein pathway and the Fas ligand pathway. Apoptosis is the primary mechanism for both of these pathways. One pathway is the cytotoxic protein pathway. In this pathway perforins and granzymes are taken up by the target cell. In this pathway, the perforins facilitate the entry of granule contents into th…
Web細胞傷害性T細胞（さいぼうしょうがいせいTさいぼう、英: cytotoxic T lymphocyte or cytotoxic T cell; TcまたはCTL）とは、リンパ球T細胞のうちの一種で、宿主にとって異物になる細胞（移植細胞、ウイルス感染細胞、癌細胞など）を認識して破壊する。 キラーT細胞（英: killer T cell ）とも呼ばれる 。 Weba) Antigen presented via MHC class I is recognized by CTLs. b) APC presentation occurs to both TC and TH cells. c) Fas-FasL signaling pathway is activated, triggering apoptosis in target cell. d) Histamine is released from cytoplasmic granules, recruiting macrophages to the site of infection.
Fas ligand or FasL is a homotrimeric type II transmembrane protein that belongs to the tumor necrosis factor (TNF) family. It signals through trimerization of FasR, which spans the membrane of the target cell. This trimerization usually leads to apoptosis, or programmed cell death. Soluble Fas ligand is generated by cleaving membrane-bound FasL at a conserved cleavage site by the external matrix metalloproteinase MMP-7.

WebSep 1, 1997 · CTLs are relatively more resistant than tumor targets in their susceptibility to cell-mediated cytotoxicity. 7 Also, not all Fas + target cells are susceptible to FasL-based killing. 6 Thus, it is necessary to directly test whether FasL-bearing tumor cells can kill tumor-specific CTLs. notfallapotheke wolfratshausenWebDec 2, 2024 · CD8+细胞，通常也称为细胞毒性T淋巴细胞（CTL细胞），是适应性免疫系统的关键组成部分，在免疫系统抵御病原体（如病毒、细菌和肿瘤）中发挥重要作用。 ...
