Abstract

The effects of various doses (0, 15, 30, 45, and 60 mg/d) of supplementary beta-carotene were evaluated. The percentage of lymphoid cells with surface markers for T-helper and natural killer (NK) cells and cells with interleukin 2 (IL-2) and transferrin receptors were significantly and substantially increased in peripheral blood mononuclear cells collected from older human adult volunteers after supplementation with greater than or equal to 30 mg beta-carotene/d for 2 mo. The increase in the percentage of cells with markers of NK cells and in expression of IL-2 receptors was dose dependent. The plasma concentrations of beta-carotene were also elevated significantly; however, there was no increase in the amount of retinol present in plasma. This indicated that immunomodulation induced by beta-carotene may be due to the carotenoid rather than to an increased amount, and hence actions, of vitamin A. These results support the role of immunostimulation as a potential mechanism of action of beta-carotene with cancer-prevention potential.

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.
