Functional dissection of the granzyme family: cell death and inflammation

Abstract excerpt

Cytotoxic lymphocytes rapidly respond and destroy both malignant cells and cells infected with intracellular pathogens. One mechanism, known as granule exocytosis, employs the secretory granules of these lymphocytes. These include the pore-forming protein perforin (pfp) and a family of serine proteases known as granzymes that cleave and activate effector molecules within the target cell. Over the past two...
