The advantage of working with T cells is that T cells don't just recognize the surface of an organism like an antibody does. They recognize any protein within the parasite — even inside the parasite. Those proteins inside the parasite don't change, or change very little from one organism to another, whereas the proteins on the surface — the ones that are recognized by the antibodies — they do change from one parasite to another. We worked out a way to induce that population of T cells in a vaccine strategy. Those T cells, at least in our mouse model, have proven to be very effective in killing multiple strains of the parasite.
