1. It has been learned in several experimental systems that proliferation and differentiation of T lymphocytes in response to tumor cells is low because tumor cells lack necessary costimulatory molecules for lymphocyte activation. If melanoma cells from a patient were induced to expres these coestimulatory molecules by transfection, production of an effective antitumor response might occur. Which of the following molecules would be the best candidate for transfection of tumor cells to achieve this end?
a)B7
b)CD2
3)CD4
4)CD28
5)LFA-1
