Persistence of T15 GVL effect postsyngeneic BMT is not dependent on or enhanced by in vivo B7 costimulation. Mice surviving until 105 days post BMT having received either C1498, C1498B7-1, or C1498B7-2 leukemia and T15 CTLs were rechallenged with 2 ×105 C1498 leukemia cells. Control mice received syngeneic BMT alone 105 days before. P values shown are compared to control BMT group.
