The aim of this study was to investigate the regulation of the 5-lipoxygenase pathway of arachidonic acid metabolism by lymphocytes using the monocyte-like cell line, THP-1. When THP-1 cells were incubated over 4-7 days in 10% supernatant from lectin-activated human lymphocytes, their capacity to synthesize 5-lipoxygenase products was significantly increased. In contrast, the supernatant from n...
Previously, we isolated the murine "leukocyte-type" 12-lipoxygenase (L-12LO) cDNA from RNA of peritoneal-elicited cells that consisted predominantly of leukocytes (Chen, X.-S., Kurre, U., Jenkins, N. A., Copeland, N. G., and Funk, C. D. (1994) J. Biol. Chem. 269, 13979-13987). By in situ hybridization we show that the L-12LO gene is expressed abundantly in a subset of peritoneal macrophages but...
The aim of this study was to examine the role of lymphocytes in regulating expression of the 5-lipoxygenase pathway in monocytes. When monocytes were cultured over a period of days with lymphocytes, calcium ionophore-stimulated 5-lipoxygenase activity was enhanced. If lymphocytes alone were activated with lectins and their supernatants added to monocytes, stimulated 5-lipoxygenase activity was ...
Previous studies involving transfection of cDNAs for 5-lipoxygenase-activating protein (FLAP) and 5-lipoxygenase into osteosarcoma cells have shown that both these proteins are essential for leukotriene synthesis (Dixon, R. A. F., Diehl, R. E., Opas, E., Rands, E., Vickers, P. J., Evans, J. F., Gillard, J. W., and Miller, D. K. (1990) Nature 343, 282-284). In the present study we show that FLAP...
