WebAbstract Granzymes are serine proteases mainly found in cytotoxic lymphocytes. The most-studied member of this group is granzyme B, which is a potent cytotoxin that has set the paradigm that all granzymes are cyototoxic. In the last 5 years, this paradigm has become controversial. On one hand, there …
WebFeb 6, 2024 · Granzymes are a family of cytotoxic proteases that each act on unique sets of biological substrates within target cells, usually to induce cell death. Granzymes are differentially expressed within T cells, depending on their environment and activation state, making the granzyme cytotoxic pathway dynamic and responsive to individual … dan charlsonWebJan 1, 2002 · Perforin is believed to be principally responsible for the translocation of granzyme B from cytotoxic cells into target cells; the granzyme B then migrates to the target cell nucleus to participate in triggering apoptosis.4 The roles of perforin in immune regulation still have not been well defined.
