We show here that in circulating monocytes , NF-Y binding activity is not detected on the CCAAT motif present in the promoters of genes such as major histocompatibility complex (MHC) class II , gp91-phox , mig , and fibronectin, whereas during macrophage differentiation , a progressive increase in NF-Y binding activity is observed on these promoters.
