RT Journal Article SR Electronic T1 Regulation of Cytochrome P450 by Inflammatory Mediators: Why and How? JF Drug Metabolism and Disposition JO Drug Metab Dispos FD American Society for Pharmacology and Experimental Therapeutics SP 207 OP 212 VO 29 IS 3 A1 Edward T. Morgan YR 2001 UL http://dmd.aspetjournals.org/content/29/3/207.abstract AB Expression and activities of cytochrome P450 enzymes are down-regulated in the liver during the host response to inflammation or infection, leading to alterations in drug clearance and toxin activation. This review focuses on recent studies on the mechanisms of this down-regulation, as well as the cytokines and cell types involved. Possible reasons for cytochrome P450 down-regulation are discussed.
