WebMar 21, 2024 · Granzyme B has a role in atherosclerotic plaque development. Data indicate that all-trans retinoic acid (ATRA), which induces miR-23a expression, decreases cathepsin C (CTSC) expression and granzyme B activity leading to impaired NK cell cytotoxicity. Granzymes are serine proteases released by cytoplasmic granules within cytotoxic T cells and natural killer (NK) cells. They induce programmed cell death (apoptosis) in the target cell, thus eliminating cells that have become cancerous or are infected with viruses or bacteria. Granzymes also kill bacteria and inhibit viral replication. In NK cells and T cells, granzymes are packaged in cytotoxic granules along with perforin. Granzymes can also be detected in the rough endoplasmic reticulu…
