Abstract

Significance: Antibodies targeting PD-1 have elicited clinical responses in multiple tumors. Nevertheless, response to anti–PD-1 interventions is limited to a fraction of patients, and a comprehensive understanding of the signaling downstream of PD-1 could provide biomarkers for tumor response. We used affinity purification-mass spectrometry to uncover proteins associated with PD-1 and found that the adaptor protein SAP inhibits PD-1 functions by blocking the enzymatic interaction between the phosphatase SHP2 and the subset of its substrates that also bind to SAP. Signaling downstream of PD-1 in T cell subsets did not correlate with PD-1 expression but was inversely correlated with SAP levels. Thus, SAP is a modulator of PD-1 function and a potential biomarker for reduced responses to PD-1–based interventions.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • SHP2 has effects on parallel pathways (e.g., JAK/STAT signaling) and is implicated as an effector of inhibitory signaling by PD-1 and some other immune checkpoint receptors.

    “SHP2 also has effects on parallel pathways (e.g., JAK/STAT signaling) and is implicated as an effector of inhibitory signaling by PD-1 and some other immune checkpoint receptors (Hui et al., 2017; Peled et al., 2018; Yokosuka et al., 2012).”

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.
