Leptin levels are strongly correlated with those of GH-binding protein in prepubertal children.

- There was a highly significant correlation between serum levels of leptin and those of GHBP, except in children with GHD. The possibility that leptin could mediate the effects of body fat mass on GH sensitivity, therefore, merits further investigation.

Different subcellular localization of cytochrome b and the dormant NADPH-oxidase in neutrophils and macrophages: effect on the production of reactive oxygen species during phagocytosis.
- 1995
-
Ingår i: Cellular immunology. - : Elsevier BV. - 0008-8749. ; 161:1, s. 61-71

Tidskriftsartikel (refereegranskat)abstract
- When neutrophils and macrophages phagocytose a prey, e.g., complement (C3b)-opsonized yeast particles, the oxygen radical generating NADPH-oxidase is activated. In neutrophils, most of the production of oxygen metabolites occurred in an intracellular compartment, possibly in the phagolysosome. In contrast, no intracellular production could be detected in human macrophages. In these cells, the subcellular localization of the superoxide-generating NADPH-oxidase and associated cytochrome b was assessed in intact cells with indirect immunofluorescence and confocal laser scanning microscopy, and with subcellular fractionation, using centrifugation on Percoll density gradients. A dual localization of the cytochrome b as well as the dormant NADPH-oxidase activity in neutrophils was in agreement with earlier immunocytochemical, biochemical, and subcellular fractionation studies. Furthermore, most of the activity was recovered from the specific granules, whereas only a small fraction was retained in the plasma membrane. In contrast, the cytochrome b/NADPH-oxidase activity in macrophages localized primarily in the plasma membrane fraction. We suggest that the macrophages are incapable of producing reactive oxygen species intraphagosomally, due to an absence of a granule-localized pool of the membrane components of the NADPH-oxidase.

Different expression and mobilisation of the complement regulatory proteins CD35, CD55 and CD59 in neonatal and adult neutrophils
- 1997
-
Ingår i: Biology of the neonate. - : S. Karger AG. - 0006-3126. ; 72:1, s. 15-21
-
Tidskriftsartikel (refereegranskat)abstract
- We investigated the expression and the N-formyl-methionyl-phenylalanine (fMLP)- and interleukin-8 (IL-8)-induced mobilisation of the complement regulatory proteins CR1 (CD 35), decay-accelerating factor (CD55) and CD59 on neutrophils in neonates and adults. The expression of CD35 on resting neonatal neutrophils was significantly higher than in adults. Both fMLP and IL-8 increased CD35 expression more markedly in adults. CD55 on resting neutrophils in neonates was significantly higher than in adults, but did not further increase upon fMLP stimulation as opposed to adults. The increase in CD59 expression was more pronounced in adult neutrophils and was significantly higher than in neonates after fMLP activation. The addition of the protease inhibitor phenylmethanesulphonyl fluoride during fMLP activation improved the upregulation of CD 3 5 significantly more in neonates, but not CD 55 or CD59. This effect could be replaced by human normal sera. These data demonstrate that differences exist between neonatal and adult neutrophils with respect to the expression and mobilisation of functional receptors related to protection from autologous complement lysis and may indicate differences in the efficiency to circumvent complement-mediated cell damage at the inflammatory site.
