Targeted Cell-to-Cell Delivery of Protein Payloads via the Granzyme-Perforin Pathway

Molecular Therapy: Methods & Clinical Development, 2017
There is great potential for engineering cellular therapeutics by repurposing biological systems. Here, we report utilization of the granzyme-perforin pathway of cytotoxic lymphocytes as a cell-to-cell protein delivery module. We designed and constructed

Granzyme B Attenuates Bacterial Virulence by Targeting Secreted Factors

iScience, 2020
Summary: Pathogenic bacteria secrete virulence factors that interact with the human host to establish infections. The human immune system evolved multiple mechanisms to fight bacterial invaders, including immune proteases that were demonstrated to ...

Fighting viral infections and virus-driven tumors with cytotoxic CD4+ T cells [PDF]

, 2017
CD4+ T cells have been and are still largely regarded as the orchestrators of immune responses, being able to differentiate into distinct T helper cell populations based on differentiation signals, transcription factor expression, cytokine secretion, and

Granzyme K Displays Highly Restricted Substrate Specificity That Only Partially Overlaps with Granzyme A [PDF]

Journal of Biological Chemistry, 2009
Granzymes are serine proteases stored in cytolytic granules of cytotoxic lymphocytes that eliminate virus-infected and tumor cells. Little is known about the molecular mechanism and function of granzyme (Gr)K. GrK is similar to GrA in that they are the only granzymes that display tryptase-like activity.

The TreaT-Assay: A Novel Urine-Derived Donor Kidney Cell-Based Assay for Prediction of Kidney Transplantation Outcome [PDF]

, 2019
Donor-reactive immunity plays a major role in rejection after kidney transplantation, but analysis of donor-reactive T-cells is not applied routinely. However, it has been shown that this could help to identify patients at risk of acute rejection.

Asp-ase Activity of the Opossum Granzyme B Supports the Role of Granzyme B as Part of Anti-Viral Immunity Already during Early Mammalian Evolution. [PDF]

PLoS ONE, 2016
Granzyme B is one of the key effector molecules in our defense against viruses and intracellular bacteria. This serine protease together with the pore forming protein perforin, induces caspase or Bid-dependent apoptosis in target cells.

The immunological advantage of owned cats over stray cats: a comparative study of perforin and granzymes gene expressions

Acta Veterinaria, 2023
Some cats live at home with their owners while others live unattended on the streets or in shelters. One might expect that the owned cats would be better prepared for diseases with vaccinations, and good care and feeding conditions whereas the stray cats
