Costimulation has been shown to be required for optimal activation of T cells and it could be delivered either in trans with respect to the source of CD3-TCR ligation or in cis on the same cell. Here the authors show that CD137 costimulation is more effective when delivered in cis to enhance T cell proliferation and activation.
