In several examples, subjects can be treated by transplanting a therapeutically effective amount of activated T cells that recognize an antigen of interest and by administering a therapeutically effective amount of a PD-1 antagonist. Methods are also disclosed for determining the efficacy of a PD-1 antagonist in a subject administered the PD-1 antagonist. In some embodiments, these methods include measuring proliferation of memory B cells in a sample from a subject administered the PD-1 antagonist. | 08-27-2015 |
