Abstract

Recent studies have demonstrated that Th2 cytokines, such as interleukin-4 and interleukin-13, enhance fibrotic processes by activating fibroblast proliferation and collagen production, whereas interferon-gamma, a Th1 cytokine, inhibits these processes. Th1 and Th2 cells both differentiate from common T precursor cells, with transcription factor GATA-3 a key regulator of Th2 differentiation. In the present study, therefore, we examined the effects of GATA-3 overexpression on the development of pulmonary fibrosis in a mouse model. Wild-type C57BL/6 mice and GATA-3-overexpressing (GATA-3-tg) mice of the same background were intratracheally treated with bleomycin. The survival rate after bleomycin was significantly decreased in GATA-3-tg mice compared with wild-type mice. The degree of pulmonary fibrosis was much greater in GATA-3-tg mice than in wild-type mice 28 days after bleomycin treatment. Lung interferon-gamma concentration was significantly decreased in GATA-3-tg mice compared with wild-type mice by 7 days after either saline or bleomycin treatment. The concentration of transforming growth factor-beta, a fibrogenic cytokine, was significantly higher in GATA-3-tg mice than in wild-type mice. Exogenous administration of interferon-gamma to GATA-3-tg mice improved the degree of pulmonary fibrosis and thus increased survival. These results indicate that overexpression of GATA-3 enhances the development of pulmonary fibrosis, possibly by reducing interferon-gamma levels in the lung.

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.
