Why the study?
Does lipopolysaccharide stimulation of RAW 264.7 cells produce a mediator that suppresses lipoprotein lipase activity in 3T3-L1 cells?

This study identifies a macrophage-derived, LPS-induced protein mediator that inhibits lipoprotein lipase, providing a potential mechanism linking inflammation and altered lipid metabolism.
May link macrophage inflammation to LPL suppression and lipid changes; leaves open in vivo relevance and clinical translation.
RAW 264.7 cells upon stimulation with lipopolysaccharide secrete a protein mediator(s) that suppresses lipoprotein lipase activity in differentiated 3T3-L1 cells. The mediator(s), which is absent from unstimulated culture supernatants, is nondialyzable and thermolabile. Preliminary characterization suggests that this mediator(s) may be the same as that previously found in medium from lipopolysaccharide-treated thioglycollate-elicited mouse peritoneal macrophage cultures.
