Abstract

CD4+CXCR5+Foxp3+ follicular regulatory T cells (TFR cells) inhibit humoral immunity mediated by CD4+CXCR5+Foxp3− follicular helper T cells (TFH cells). Although the inhibitory receptor PD-1 is expressed by both cell types, its role in the differentiation of TFR cells is unknown. Here we found that mice deficient in PD-1 and its ligand PD-L1 had a greater abundance of TFR cells in the lymph nodes and that those TFR cells had enhanced suppressive ability. We also found substantial populations of TFR cells in mouse blood and demonstrated that TFR cells in the blood homed to lymph nodes and potently inhibited TFH cells in vivo. TFR cells in the blood required signaling via the costimulatory receptors CD28 and ICOS but were inhibited by PD-1 and PD-L1. Our findings demonstrate mechanisms by which the PD-1 pathway regulates antibody production and help reconcile inconsistencies surrounding the role of this pathway in humoral immunity.

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.
