Chemotactic for Human Granulocytes
A biologically active glutathione adduct of the eicosanoid 5-oxo-eicosatetraenoic acid has been observed as a product formed within the murine peritoneal macrophage. This five-oxo glutathione adduct (FOG 7 ) was structurally characterized using electrospray tandem mass spectrometry as a 1,4 Michael addition product 5-oxo-7-glutathionyl-8,11,14-eicosatrienoic acid. FOG 7 was found to be highly p...
متن کاملHuman Peripheral Blood Granulocytes
A central problem of the current studies on protooncogenes (cellular oncogenes, c-onc) is their role in the control of growth and differentiation of normal cells. The cfos protooncogene has been widely investigated and it has been demonstrated that cfos specific transcripts are induced in proliferating cells (1, 2) and during differentiation (3-6) . In particular, when HL60 (promyelocytic) and ...
متن کاملHistaminase release from human granulocytes
Histaminase (EC-1.4.3.6), one of the two catabolic enzymes for histamine, is contained in human granulocytes. Opsonized zymosan or the calcium ionophore A-23187 induce a dose-dependent release of histaminase from human granulocytes in vitro. Release is completed within 30 min, is temperature dependent, and requires divalent cations. Opsonized zymosan-induced histaminase release was maximal in t...
متن کاملCryopreservation of human granulocytes in liquid nitrogen.
Human granulocytes (PMNL) were successfully cryopreserved for up to 14 months. The PMNL (1-2 X 10(7)/ml) were stored in 2-ml ampoules in the gas phase of liquid nitrogen at a temperature between -160 degrees C and -196 degrees C using dimethylsulphoxide (DMSO 10%) as cryoprotectant. Morphology and phagocytic and bactericidal capacity were best preserved by adding fetal calf serum to the freezin...
متن کاملChemotactic factor inactivators of human granulocytes.
During phagocytosis, neutrophils release a variety of substances that include activators and inactivators of chemotactic factors. It is generally considered that these represent hydrolytic enzymes. Elastase and cathepsin G, major proteases released from lysosomal granules during phagocytosis, contain broad hydrolytic activity. This study examined granule elastase and cathepsin G for their role ...
