WebInterleukin (IL)-13 is a major inducer of fibrosis in many chronic infectious and autoimmune diseases. In studies of the mechanisms underlying such induction, we found that IL-13 induces transforming growth factor (TGF)-beta(1) in macrophages through a two-stage process involving, first, the induction of a receptor formerly considered to function only as … Web1,4-addition reaction of quinone with hydrogen chloride to produce chlorohydroquinone. Quinones can undergo Diels-Alder reactions. [9] The quinone acts as the dienophile and reacts with a diene at a carbon-carbon double bond. In Diels-Alder reactions quinones are used as dienophiles.
