1,25-Dihydroxyvitamin D 3 : a Novel Immunoregulatory Hormone

Tsoukas, Constantine D., Provvedini, Diego M., Manolagas, Stavros C.·1984·Science

Abstract

The hormonal form of vitamin D 3 , 1,25-dihydroxyvitamin D 3 [1,25(OH) 2 D 3 ], at picomolar concentrations, inhibited the growth-promoting lymphokine interleukin-2, which is produced by human T lymphocytes activated in vitro by the mitogen phytohemagglutinin. Other metabolites of vitamin D 3 were less effective than 1,25(OH) 2 D 3 in suppressing interleukin-2; their order of potency corresponded to their respective affinity for the 1,25(OH) 2 D 3 receptor, suggesting that the effect on interleukin-2 was mediated by this specific receptor. The proliferation of mitogen-activated lymphocytes was also inhibited by 1,25(OH) 2 D 3 . This effect of the hormone became more pronounced at later stages of the culture. These findings demonstrate that 1,25(OH) 2 D 3 is an immunoregulatory hormone.

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.
