Antibody targeting of Cathepsin S induces antibody-dependent cellular cytotoxicity

Antibody research targeting Cathepsin S for cancer therapy

Cathepsin S is a cysteine protease highly expressed in many type of cancers including colorectal, prostate, breast, and glioblastoma’s. It is involved in tumor progression through extracellular matrix remodeling. In recent years, antibody research specifically targeting Cathepsin S to block/inhibit tumorigenic effects were generated some positive preclinical data. This antagonistic antibody was...

[Enhancement of antibody-dependent cellular cytotoxicity by tandem Fc multimerization].

Monoclonal antibodies are being used as therapeutics for a number of cancers, such as leukemia, breast and colon cancers, and a lot of monoclonal antibodies specific for tumor-related antigens have been on clinical trials. Antibody-dependent cellular cytotoxicity (ADCC) is one of the major mechanisms by which antibodies exert anti-tumor effects. ADCC occurs through interaction between the Fc do...

GM-CSF Enhances 3F8 Monoclonal Antibody-Dependent Cellular Cytotoxicity

3F8 is a murine monoclonal IgG3 antibody specific for the tumor-associated antigen ganglioside G . Previous in vitro studies suggest that tumor regressions observed in a phase I clinical trial of 3F8 may be attributable to complement activation by 3F8 and to 3F8-dependent cellular cytotoxicity (ADCC) with lymphocytes. We now describe 3F8-mediated ADCC of G -positive tumor targets (melanoma and ...
