title: Release of leukotrienes C (LTC) and D (LTD) from inflammatory macrophages during phagocytosis of zymosan and bacteria.
abstract: Release of slow-reacting substance (SRS) was obtained from resident mouse peritoneal macrophages (R-M phi) upon stimulation with phagocytic stimuli (zymosan, bacteria). The release of SRS from thioglycollate elicited M phi was impaired, whereas that from BCG-elicited M phi was quantitatively unaffected. However, using a high pressure liquid chromatography separation procedure, qualitative variations between SRS released from R-M phi and BCG-M phi were observed. In both cases, LTC was the major component released from M phi, but greater amounts of LTD were released from BCG-M phi than from R-M phi. These data indicate that local environment alters leukotriene generation by M phi.
