Sequence of αPD-1 relative to local tumor irradiation determines the induction of abscopal antitumor immune responses

Abstract

T cells at the irradiated tumor site generated a suboptimal systemic antitumor response and the loss of abscopal responses. Therefore, this report maximizes the potential synergy between radiotherapy and αPD-1 immunotherapy, information that will benefit clinical combinations of radiotherapy and immune checkpoint blockade.
