WebJul 2, 2024 · Expression of granzyme B and perforin is also high in this subset compared with CD56bright NK cells. 2) CD56bright NK cells: This subtype comprises up to 10% of NK cells. This subset is known as the cytokine producing subset of NK cells, and rapidly produces cytokines and chemokines including IFNγ, TNFα, GMCSF after activation. WebA main pathway used by cytotoxic T lymphocytes (CTLs) and natural killer cells to eliminate pathogenic cells is via exocytosis of granule components in the direction of the target cell, delivering a lethal hit of cytolytic molecules. Amongst these, granzyme B and perforin have been shown to induce CTL-mediated target cell DNA fragmentation and ...

WebNov 11, 2024 · Granzyme B (GrB) is a serine protease produced by a variety of immune, non-immune and tumor cells. Apoptotic intracellular and multiple extracellular functions of GrB have been recently identified. Its capability of cleaving extracellular matrix (ECM) components, cytokines, cell receptors and clotting proteins, revealed GrB as a potential ... WebAs previously stated, ILC3 can secrete IFN-γ in response to inflammatory factor stimulation, which is also found in the blood and tonsil-derived ILC3s. Current research has shown that ILC3 can acquire cytotoxic activity and even develop into NK cells to secret perforin and granzyme B (68–71). This might be one of the ways it prevents ...
