MHC class II-transfected tumor cells directly present antigen to tumor-specific CD4+ T lymphocytes.

Abstract excerpt

We have developed and shown to be efficacious an immunotherapeutic strategy to enhance the generation of tumor-specific CD4+ T helper lymphocytes. The approach uses autologous tumor cells genetically modified to express syngeneic MHC class II genes as cell-based immunogens and is based on the hypothesis that tumor cells directly present tumor Ags to CD4+ T cells. Since the conventional pathway for CD4+ T cell...
