Abstract

Stat1 is phosphorylated on serine 727 within its transactivating domain (TAD) in response to interferons or other immunological signals. We generated gene-targeted mutant mice expressing a serine727-alanine mutant of Stat1. These animals showed increased mortality upon infection with Listeria monocytogenes and impaired clearance of the bacteria from spleen and liver. The Stat1S727A mice were more resistant to the LPS-induced septic shock syndrome, suggesting that Stat1 serine phosphorylation promotes inflammatory responses. Expression of IFN-gamma-induced genes was strongly reduced in macrophages expressing Stat1(S727A). While mutation of Stat1 at S727 did not reduce its binding to chromatin, association with the coactivator CBP and histone acetylation at the interferon-responsive GBP promoter was strongly reduced, suggesting defective recruitment of histone acetylases as the mechanism underlying IFN-gamma hyporesponsiveness. Our data demonstrate that the increase in transcription factor activity caused by Stat serine phosphorylation contributes to macrophage activation and to IFN-gamma-dependent immune responses in vivo.

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.
