Abstract

Programmed death-1 (PD-1)–PD-1 ligand (PD-L) signaling system is involved in the functional impairment of T cells such as in chronic viral infection or tumor immune evasion. We examined PD-L expression in lymphoid cell lines and found that they were up-regulated on Hodgkin lymphoma (HL) and several T-cell lymphomas but not on B-cell lymphomas. PD-L expression was also demonstrated in primary Hodgkin/Reed-Sternberg (H/RS) cells. On the other hand, PD-1 was elevated markedly in tumor-infiltrating T cells of HL, and was high in the peripheral T cells of HL patients as well. Blockade of the PD-1 signaling pathway inhibited SHP-2 phosphorylation and restored the IFN-γ–producing function of HL-infiltrating T cells. According to these results, deficient cellular immunity observed in HL patients can be explained by “T-cell exhaustion,” which is led by the activation of PD-1–PD-L signaling pathway. Our finding provides a potentially effective immunologic strategy for the treatment of HL.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
