The role of granzyme B cluster proteases in cell-mediated cytotoxicity.

Abstract

Granzymes are neutral serine proteases that are stored in the specialized lytic granules of cytotoxic lymphocytes. A mutation introduced into the granzyme B locus leads to a severe defect in the ability of cytotoxic lymphocytes to induce apoptosis in susceptible target cells, and reduces the severity of class I-dependent acute graft-versus-host disease… (More)
