WebCytolysis through secretion of granzymes and perforine represent a prominent effector mechanism attributed to natural killer cells and cytotoxic T lymphocytes (CTLs). However, initially starting from the discovery in human tTreg cells, by now, several reports support the idea that granzyme-dependent killing of target cells represents another ...

Perforin and granzymes: function, dysfunction and human pathology
WebApr 8, 2024 · Unexpectedly, the Gzmc locus, which encodes the lytic granule–associated cytotoxic molecule granzyme C , was highly accessible, and the Gzmc transcript was expressed in cells with an ILC1 phenotype (Fig. 1, A and B). This raised the possibility that innate lymphocytes with cytotoxic potential resided among tissue-resident populations. WebApr 11, 2024 · In summary, we developed a smart NIR fluorescent probe CYGB for imaging GzmB produced by cytotoxic T lymphocytes, enabling early non-invasive diagnosis of allograft rejection. CYGB specifically generated the NIRF signal in the presence of GzmB, and a strong linear relationship between the fluorescence signal intensity at 700 nm and … cfb hall staff
