Opsonized zymosan-stimulated granulocytes-activation and activity of the superoxide-generating system and membrane potential changes.
Phagocytic cells generate superoxide in response to stimulation by opsonized particles. A continuous assay for opsonized zymosan-stimulated granulocyte superoxide production shows that there is a lag time between the addition of particles and the onset of detectable superoxide production. Superoxide production is preceded by membrane potential depolarization. Neither superoxide production nor m...
متن کاملMitochondrial DNA sequence heterogeneity in circulating normal human CD34 cells and granulocytes.
We have reported marked mitochondrial DNA (mtDNA) sequence heterogeneity among individual CD34 clones from adult bone marrow (BM) and the age-dependent accumulation of mtDNA mutations in this mitotically active tissue. Here, we show direct evidence of clonal expansion of cells containing mtDNA mutations and that the mtDNA sequence may be easily determined by using peripheral blood (PB) as a CD3...
متن کاملChemotactic 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 کاملIncreased membrane localization of pannexin1 in human corneal synaptosomes causes enhanced stimulated ATP release in chronic diabetes mellitus
In the present study, we investigated the potential changes in the corneal nerve terminals in non-insulin-dependent diabetes mellitus of moderate duration. The dissected corneas were subjected to a protocol of ultracentrifugation to obtain synaptosomes of sensory nerve terminals. Within these nerve varicosities, 2 major mechanisms were examined, viz., alterations of the mechanosensitive channel...
