Abstract

The immunosuppressive drugs rapamycin and cyclosporin A (CsA) are widely used to prevent allograft rejection. Moreover, they were shown to be instrumental in experimental models of tolerance induction. However, it remains to be elucidated whether these drugs have an effect on the CD4+ CD25+ regulatory T-cell (T(REG)) population, which plays an important role in allograft tolerance. Recently, we reported that alloantigen-driven expansion of human CD4+ CD25+ T(REG)s gives rise to a distinct highly suppressive CD27+ T(REG) subset next to a moderately suppressive CD27- T(REG) subset. In the current study we found that rapamycin and CsA do not interfere with the suppressive activity of human naturally occurring CD4+ CD25+ T cells. However, in contrast to CsA, rapamycin preserved the dominance of the potent CD27+ T(REG) subset over the CD27- T(REG) subset after alloantigen-driven expansion of CD4+ CD25+ T(REG)s in vitro. Accordingly, CD4+ CD25+ T(REG)s cultured in the presence of rapamycin displayed much stronger suppressive capacity than CD4+ CD25+ T(REG)s cultured in the presence of CsA. In addition, CD4+ CD25+ T(REG) cells cultured in the presence of rapamycin, but not CsA, were able to suppress ongoing alloimmune responses. This differential effect of rapamycin and CsA on the CD27+ T(REG) subset dominance may favor the use of rapamycin in tolerance-inducing strategies.

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.
