Abstract

Human peripheral monocytes can be induced by bacterial lipopolysaccharide to produce the inflammatory mediators interleukin 1 (IL1) and hepatocyte-stimulating (HS) activity. IL 1 and HS activities were separated by gel permeation chromatography. It is also shown that the two monokines are differently regulated. Evidence for this stems from the finding that monocytes cultured for 24 h lose their ability to produce IL 1 in response to lipopolysaccharide, while synthesis of HS activity remains essentially unaffected.
