We have studied the regulation of sialoadhesin expression in vitro and show that glucocorticoids ( GC ) induce sialoadhesin expression on freshly isolated rat macrophages and the rat macrophage cell line R2 .
 ( cell type: macrophages, None) , ( protein: sialoadhesin, None) , ( cell type: rat macrophages, None) , ( protein: sialoadhesin, None) , ( cell line: rat macrophage cell line R2, None)
