Granzyme A from cytotoxic lymphocytes cleaves GSDMB to trigger pyroptosis in target cells

Science, 2020
Granzyme A lights a fire Cytotoxic T cells and natural killer cells use several strategies to kill infected or transformed cells. One such pathway entails the delivery of a family of serine proteases called granzymes to target cells through perforin ...

Granzyme K+ CD8 T cells form a core population in inflamed human tissue

Science Translational Medicine, 2022
T cell–derived pro-inflammatory cytokines are a major driver of rheumatoid arthritis (RA) pathogenesis. Although these cytokines have traditionally been attributed to CD4 T cells, we have found that CD8 T cells are notably abundant in synovium and make ...

Beyond target cell death - Granzyme serine proteases in health and disease.

Molecular Aspects of Medicine, 2022
Granzymes are a family of small (∼32 kDa) serine proteases with a range of substrate specificities that are stored in, and released from, the cytoplasmic secretory vesicles ('granules') of cytotoxic T lymphocytes and natural killer cells.

Granzyme B as a therapeutic target: an update in 2022

Expert opinion on therapeutic targets, 2022
Introduction Granzyme B is a serine protease extensively studied for its implication in cytotoxic lymphocyte-mediated apoptosis. In recent years, the paradigm that the role of granzyme B is restricted to immune cell-mediated killing has been challenged ...

Granzymes and Mitochondria

Biochemistry (Moscow), 2020
Cytotoxic T lymphocytes and natural killer cells eliminate infected cells from the organism by triggering programmed cell death (apoptosis). The contents of the lytic granules of killer cells, including pore-forming proteins perforins and proteolytic enzymes granzymes, are released with the following penetration of the released proteins into the target

Granzyme M: behind enemy lines [PDF]

open access: yesCell Death and Differentiation, 2014
The granule-exocytosis pathway is the major mechanism via which cytotoxic lymphocytes eliminate virus-infected and tumor cells. In this pathway, cytotoxic lymphocytes release granules containing the pore-forming protein perforin and a family of serine proteases known as granzymes into the immunological synapse.

Granzymes and cell death.

Methods in enzymology, 2008
Granzymes are cell death-inducing serine proteases released from cytotoxic granules of cytotoxic T lymphocytes and natural killer cells during granule exocytosis in response to viral infection or against transformed cells marked for elimination. A critical cofactor for the granule exocytosis pathway is perforin, which mediates the entry of granzymes ...

Controversies in granzyme biology

Tissue Antigens, 2012
AbstractGranzymes (Grz) are a family of serine proteases found in the granules of cytotoxic lymphocytes and are emerging as an important group of proteins involved in immune function and surveillance. Grz have both cytotoxic and more recently reported non‐cytotoxic roles, however these functions are still subject to thorough investigation.
