Abstract

Transferrin is required by many cells for growth. Mitogen-induced T lymphocyte proliferation is dependent on the presence of both interleukin 2 (IL-2; T-cell growth factor) and transferrin, even though resting lymphocytes do not have receptors for either. Exposure to mitogen (phytohemagglutinin) alone is sufficient to induce transient appearance of IL-2 receptors on lymphocytes. Using monoclonal antibodies to the IL-2 receptor and to the transferrin receptor, we examined those signals required for transferrin receptor induction during T lymphocyte proliferation. Our study has revealed that (i) monocytes, or a monocyte substitute such as the phorbol ester tetradecanoylphorbol 13-acetate, are required for transferrin receptor expression after mitogen exposure; (ii) the presence of IL-2 receptors is necessary for transferrin receptor induction; (iii) antibody to the IL-2 receptor inhibits thymidine incorporation (DNA synthesis) in lymphocytes, but only if administered before transferrin receptors have appeared; and (iv) antitransferrin receptor antibody inhibits DNA synthesis but has minimal effect on IL-2 receptor expression. Thus, IL-2 receptor induction leads to transferrin receptor induction and subsequent initiation of DNA synthesis. These data indicate that IL-2 stimulates T lymphocyte proliferation, at least in part, by induction of transferrin receptors on these cells.

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.
