With a syringe, she injects a slurry of pink cancer cells under the skin of the animals right flank. The idea was, lets keep doing this until the wheels fall off the bus, says Masopust, a professor of immunology at the University of Minnesota. Unless the human T cells have developed in a transgenic mouse expressing human HLA, or in a mouse with a human thymus implant, then the interactions are not efficient, and the humanized immune system is probably not capable of mounting an efficient immune response to a vaccination.
