Duke Researchers Find Second Gene Linked To Blood Vessel Disorder
...or beta (TGF-_). Researchers are only beginning to unravel howTGF-_ works. Receptors for TGF-_ are found on the surface of virtually every cell ofthe body. When TGF-_ binds to these receptors, signals are relayed inside the cell. Thecellular response to TGF-_ depends on the cell type. In some cells, it sti...Duke Ecologist Says Logging Is Creating 'Mahogany Deserts'
