This paper describes how the expression of the monocyte-macrophage Ag , CD14 , and the low affinity Fc receptor for IgE , CD23 , were inversely regulated during VitD3 -and RA-induced monocytic differentiation of human U-937 monoblasts .
 ( protein: monocyte-macrophage Ag, None) , ( protein: affinity Fc receptor, None) , ( protein: CD23, None) , ( protein: CD14, None) , ( protein: IgE, None) , ( cell line: human U-937 monoblasts, None)
