abstract：:The regulation of the expression of indoleamine 2,3-dioxygenase (IDO) was studied in cloned murine macrophages (MT2) and microglial (N11) cells. Both cell lines express IDO and inducible nitric oxide synthase activity after interferon-gamma (IFN-gamma) stimulation. The regulation of IDO expression appears to differ in...
