Dietary fat and reduced levels of TGFbeta1 act synergistically to promote activation of the vascular endothelium and formation of lipid lesions.


Transforming growth factor-(beta) (TGF(beta)) has a wide range of activities on vascular cells and inflammatory cells, suggesting it may have different functions during various stages of atherogenesis. We report that mice heterozygous for the deletion of the tgfb1 gene (tgfb1(+/-) mice) have reduced levels of TGF(beta)1 in the artery wall until at least 8… (More)
