(Oberoi, 2013)Ĭreative Biolabs is dedicated to helping you develop antibody-granzyme B fusion protein by using readily available or customized strategies. Cellular uptake of granzyme B and targeted granzyme B fusion proteins. However, the challenges also exist for future development and clinical application of GrB antibody proteins such as the presence of the endogenous inhibitor, intracellular serpin protease inhibitor.įig 2. The utilization of GrB antibody proteins for cancer therapy is a promising therapeutic strategy. Some in vivo studies revealed that the fusion protein was capable of inhibiting tumor growth and sensitizing the tumor cells to chemotherapy and radiotherapy. The fusion protein was also found to retain the natural catalytic activity of GrB. Granzyme B has shown to be cytotoxic to a variety of tumors, including tumor vasculature, carcinomas, acute myeloid leukemia, and melanoma. GrB plays a critical role in stimulating multiple apoptotic pathways including directly activating caspases, inducing DNA fragmentation, activating the mitochondrial death pathway, and/or directly cleaving the nuclear matrix.įig.1 The Granzyme B-perforin cytotoxic pathway. There are five classes of human granzymes, of which GrB was found to be the most potent functionally and acts as an effective cytotoxic when linked to antibodies or growth factors (e.g., VEGF). The function of granzyme is dependent on the presence of perforin, which establishes pores in the cell membrane to facilitate the entry of granzymes into the cell. Recently, Granzyme B has also been found to be produced by a wide range of non-cytotoxic cells ranging from basophils and mast cells to smooth muscle cells. Granzymes are serine proteases that exist in the granules of cytotoxic lymphocytes (CTLs), natural killer cells (NK cells) and cytotoxic T cells. ![]() Here, we offer high-quality antibody-granzyme B protein fusion service in cost-effective manners for immunotherapy.
