Cultured human monocytes synthesize and secrete alpha2-macroglobulin
alpha2-Macroglobulin levels in the supernates of cultures of different subpopulations of human peripheral blood mononuclear leukocytes were assayed by a radioimmunoassay. Unfractionated mononuclear leukocytes produced greater amounts of the macroglobulin (4.0 vs. 0.8 ng/10(6) cells) than did subpopulations enriched in T or B+T lymphocytes, by passage through nylon wool or cotton wool columns, r...
متن کاملMonocytes and macrophages synthesize and secrete thrombospondin.
Thrombospondin, one of the major glycoproteins released from alpha-granules of thrombin-stimulated platelets, is a disulfide-linked trimer of 160,000-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 micrograms/10(6) cells/24 hr); secretion was totally blocked by cyclohe...

متن کاملC-reactive protein induces human peripheral blood monocytes to synthesize tissue factor.
The acute inflammatory response is frequently accompanied by serious thrombotic events. We show that C-reactive protein (CRP), an acute-phase reactant that markedly increases its serum concentration in response to inflammatory stimuli, induced monocytes to express tissue factor (TF), a potent procoagulant. Purified human CRP in concentrations commonly achieved in vivo during inflammation (10 to...
متن کاملHuman Endothelial Cells Synthesize Protein
Human umbilical vein endothelial cells were analyzed for the presence of prothrombin. factor VII, protein C, and protein S in culture supernatants and cell extracts using specific radioimmunoassays. Only protein S was detected. Conditioned medium from 24-hour cultures and cell lysates contained 21.7 ng/mL and 88.8 ng/107 cells of protein S, respectively. Intrinsic labeling and immunoprecipitati...
