WebApr 11, 2024 · Graft injury is a downstream effect of the anti-graft T-cell response. Detection of specific markers produced by cytotoxic T lymphocytes has the potential for the early diagnosis of rejection.Therefore, we assessed the potential of CYGB imaging of GzmB to detect allograft rejection. WebAbstract Granzymes are serine proteases mainly found in cytotoxic lymphocytes. The most-studied member of this group is granzyme B, which is a potent cytotoxin that has set the paradigm that all granzymes are cyototoxic. In the last 5 years, this paradigm has become controversial. On one hand, there …
WebApr 13, 2024 · The cytotoxic activity of NK92-cells is largely dependent on two pathways: the perforin/granzyme pathway and the death-receptor pathway, the latter being activated by FasL or TRAIL [19, 20, 35]. As previously described, knockout of Prf1 leads to abrogation of apoptosis induction via the perforin/granzyme pathway [ 36 , 37 ]. WebGranzyme A is expressed in NK cells as well as cytotoxic T cells. In one transgenic line, Ly49A was expressed in NK cells and half of all T cells and a reduction in NK cell (NK1.1 + CD3 − cells) number was noted in the blood, spleen, liver and lung (Kim et al., 2000). This transgenic line also exhibited a reduction in IFN-γ production in ...
