The three regions concerned are: 1) a region between -73 and -36, which is the minimal element inducible by LPS or TNF-alpha ; 2) an element located between -181 and -73, which appeared to regulate the response to IFN-gamma and TNF-alpha negatively; and 3) a distal element upstream of -224, which was inducible by IFN-gamma alone.
