Monocytes and Macrophages Synthesize and Secrete

چکیده
Thrombospondin, one of the major glycoproteins released from a-granules of thrombin-stimulated platelets, is a disulfide-linked trimer of 1 60,000-dalton subunits. Cultured human monocytes secreted thrombospondin (determined by an enzyme-linked immunosorbent assay) into the culture medium in a time-dependent manner (1 .45 g/10’ cells/24 hr); secretion was totally blocked by cycloheximide (1 g/mL). S-thrombospondin was isolated from 35Smethionine-labeled human monocyte postculture medium with rabbit polyclonal anti-thrombospondin coupled to protein A-Sepharose. The immunoisolated 35S-thrombospondin migrated in sodium dodecyl sulfate-polyacrylamide gels

متن کامل[Effect of lipoprotein on LPL activity of guinea pig alveolar macrophages].
Macrophages may play an important role in the atherogenic process because they appear to be precursors of some arterial wall foam cells. Recently, it has been reported that human peripheral monocytes in culture synthesize and secrete lipoprotein lipase (LPL). LPL catalyzes the hydrolysis of triglycerides which are transported in plasma by chylomicrons and very low density lipoprotein (VLDL) . C...
متن کاملMacrophages as origin of factor increasing monocytopoiesis
Earlier investigations had indicated that the factor increasing monocytopoiesis (FIM), present in the serum of mice and rabbits during the onset of an inflammatory response, is released by cells of the inflammatory exudate. The present study was performed to determine which cells produce and secrete this factor and to establish the kinetics of its production and secretion. FIM was assayed in vi...
متن کاملEndocytic and NBT-reduction activities and TNF expression by macrophages and monocytes of the armadillo (Dasypus novemcinctus)
The armadillo could be considered as an experimental model for leprosy studies. Mycobacterium leprae main host cells are macrophages and Schwann cells. However, endocytosis and germicidal activities of armadillo macrophages and monocytes have not yet been evaluated. The aim of this research was to evaluate endocytosis and NBT-reduction activities of monocyte-derived macrophages (MDM) and monocy...
متن کاملLipoprotein lipase secretion by human monocyte-derived macrophages.
Human monocyte-derived macrophages in culture produced lipoprotein lipase. Although freshly isolated blood monocytes did not secrete much lipase activity, 1 d in culture was sufficient to trigger measureable enzyme production. During 3 wk in culture, maximal activity was attained after 7 d. At all times, the culture medium contained more enzyme activity than did a serum-heparin eluate or a dete...
