Regulation of MHC class II gene expression in macrophages by hematopoietic colony-stimulating factors (CSF). Induction by granulocyte/macrophage CSF and inhibition by CSF-1

CSF-1 and granulocyte/monocyte CSF (GM-CSF) were shown to modulate the levels of Ia gene and protein expression in bone marrow-derived macrophages (BMM). Recombinant GM-CSF induced high levels of Ia expression, similar to the levels induced by INF-gamma, while IL-3 had no effect. In contrast, recombinant CSF-1 not only suppressed the basal levels of Ia gene and protein expression in BMM, but al...

Respiratory burst in adherent human neutrophils: triggering by colony-stimulating factors CSF-GM and CSF-G.

Human neutrophils adherent to proteins derived from serum or plasma, or to the basement membrane protein laminin, underwent a delayed but massive respiratory burst in response to recombinant human CSF-GM or CSF-G. No such response was elicited from neutrophils in suspension. On a molar basis, CSF-GM (EC50 approximately 126 pmol/L) and CSF-G (EC50 approximately 585 pmol/L) were about as potent a...

Respiratory Burst in Adherent Human Neutrophils : Triggering by Colony - Stimulating Factors CSF - GM and CSF

Human neutrophils adherent to proteins derived from serum or plasma, or to the basement membrane protein laminin. underwent a delayed but massive respiratory burst in response to recombinant human CSF-GM or CSF-G. No such response was elicited from neutrophils in suspension. On a molar basis, CSF-GM (ECW 126 pmol/L) and CSF-G (EC O 585 pmol/L) were about as potent as TNFa and TNF/9 in their eli...

THE EFFECT OF THEOPHYLLINE ON THE PRODUCTION OF COLONY STIMULATING FACTOR (CSF)BY THE LUNG

The effect of theophylline on colony stimulating factor production by the lung tissue was investigated. Addition of various concentrations of theophylline to the lung conditioned medium enhanced CSF production at 10 µg/ml and at higher concentrations showed an inhibitory effect. Determination of the phosphate content of the medium showed a decrease at 1-3 hours of incubation. Addition of A...

Receptor-mediated binding and internalization of colony-stimulating factor (CSF-1) by mouse peritoneal exudate macrophages.

Colony-stimulating factor (CSF-1) purified from L-cell-conditioned medium is a haemopoietic growth factor that specifically stimulates the proliferation and differentiation of mononuclear phagocytes. Using radioactively labelled CSF-1 [( 125I]CSF-1), the presence of specific CSF-1 receptor has been identified in the cells of the mononuclear phagocytic series and their precursors only. To determ...
