B7‐H3 is a potent inhibitor of human T‐cell activation: No evidence for B7‐H3 and TREML2 interaction
Open accessAbstract
B7‐H3 belongs to the B7 superfamily, a group of molecules that costimulate or down‐modulate T‐cell responses. Although it was shown that B7‐H3 could inhibit T‐cell responses, several studies – most of them performed in murine systems – found B7‐H3 to act in a costimulatory manner. In this study, we have specifically addressed a potential functional dualism of human B7‐H3 by assessing the effect of this molecule under varying experimental conditions as well as on different T‐cell subsets. We show that B7‐H3 does not costimulate human T cells. In the presence of strong activating signals, B7‐H3 potently and consistently down‐modulated human T‐cell responses. This inhibitory effect was evident when analysing proliferation and cytokine production and affected naïve as well as pre‐activated T cells. Furthermore, we demonstrate that B7‐H3–T‐cell interaction is characterised by an early suppression of IL‐2 and that T‐cell inhibition can be reverted by exogenous IL‐2. Since the triggering receptor expressed on myeloid cells like transcript 2 (TREML2/TLT‐2) has been recently described as costimulatory receptor of murine B7‐H3 we have extensively analysed interaction of human B7‐H3 with TREML2/TLT‐2. In these experiments we found no evidence for such an interaction. Furthermore, our data do not point to a role for murine TREML2 as a receptor for murine B7‐H3.

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.
