  • PD-1 does not uniformly suppress T cells with diverse response characteristics but preferentially suppresses T cells with low affinity to antigen.
  • Low affinity tumor-specific T cells preferentially expand in the absence of PD-1-mediated co-inhibitory signal.
  • Precise and deeper understandings of the functional characteristics of PD-1 will support the development of effective and safe immunotherapies.
