A more robust and genuine epitope, would theoretically result in a more pronounced unraveling of TAP augmentation, IMO.
I'm not a fan of PD-1 therapeutics. To randomly stimulate T-cell production, is not specialized, and has been done before. I'm all about focused, and targeted therapy, and thus my interest in Taplmmune.
PD-1 modulation is deficient in what Taplmmune's vaccine stimulates, "transporters associated with antigen processing", IMO.
