Impaired IL-12 responses and enhanced development of Th2 cells in Stat4-deficient mice

Abstract

Interactions between cytokine and receptor lead to the activation of multiple signalling molecules, including the family of signal transducer and activator of transcription (STAT) proteins. STAT4 is one member of this family, and is activated only in response to the cytokine interleukin (IL)-12 (refs 5, 6). By gene targeting, we have generated mice deficient in STAT4 to determine whether the function of this transcription factor is redundant with other signalling molecules activated by IL-12. IL-12-induced increases in the production of interferon (IFN)-gamma cellular proliferation and natural killer (NK) cell cytotoxicity are abrogated in lymphocytes from STAT4-deficient mice. The development of Th1 cells in response to either IL-12 of Listeria monocytogenes is also impaired in the absence of Stat4. Furthermore, Stat4-deficient lymphocytes demonstrate a propensity towards the development of Th2 cells. These results demonstrate that Stat4 is essential for mediating responses to IL-12 in lymphocytes, and regulating the differentiation of both Th1 and Th2 cells.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

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.
