Going forward, I would like them to transduce half of the CD4+ T-cells with an NY-ESO-1 specific MHC II restricted TCR [1], and the other half to co-express a CD8a. Combining both CD4+ and CD8+ can induce bystander killing of antigen-negative cancer cells [2,3]. Also, some of the CD4+ can show tumoricidal activity by their own means irrespective of MHC II expression [4-7].
