Core Tip
Core tip: Immunization with toll-like receptor-7 agonist conjugated with a monoclonal gastric cancer 7 antigen tri-epitope was efficacious in reversing tolerance and generating a therapeutic response in Ehrlich ascites carcinoma tumor-bearing mice. This occurred by enhancing the specific humoral and cellular immunity, which were displayed as higher antibody titers, antibody-dependent cell-mediated cytotoxicity, and cytotoxic T lymphocyte activity.
