PD-1 is an inhibitory receptor induced in T cells by antigen stimulation and
sustained PD-1 expression plays a key role in T cell dysfunction. Blocking PD-1
signaling rescues exhausted T cells and is an effective treatment for chronic
infections and cancer. Nonetheless, combining PD-1 pathway blockade to
therapeutic vaccination should further improve T cell rescue. PD-1 is induced
shortly after T cell priming, but little is known about the role of PD-1 in the
initiation of immune responses. In addition, the PD-1 pathway may also modulate
humoral responses, since both B cells and Tfh cells express PD-1. Therefore, even
though much progress has been achieved by manipulation of the PD-1 pathway to
rescue exhausted T cells, this powerful immunotherapy could still be further
exploited.
