Monocytes (MO) cultured for > or =5 days with either macrophage-CSF (M-CSF) or granulocyte macrophage (GM)-CSF and IL-4 differentiated without concomitant proliferation into CD14+ macrophages (Mphi) or CD1a+ dendritic cells (DC), respectively. When adherent and nonadherent CD14high Mphi from M-CSF cultures were separated and cultured further in(More)
Crohn's disease is a chronic intestinal inflammatory process. In modern therapy, TNF-alpha inhibition is the main goal. The aim here is to characterize the effects of Celastrol, a pentacyclic-triterpene, on the secretion of inflammatory cytokines by LPS-activated human cells. Celastrol dose-dependently inhibited the secretion of all tested pro-inflammatory(More)
Crohn's disease (CD) is a multifactorial chronic inflammatory bowel disease of unknown cause. The aim of the present study was to explore if mRNA over-expression of SSTR5 and CCR7 found in CD patients could be correlated to respective protein expression. When compared to healthy donors, SSTR5 was over-expressed 417 +/- 71 times in CD peripheral blood(More)
We examined whether priming monocytes (MO) with lipopolysaccharide (LPS) influenced their further differentiation into either macrophages (Mphi) or dendritic cells (DC). LPS-primed MO differentiated into Mphi when cultured further with Mphi colony-stimulating factor (M-CSF) but, if cultured then with granulocyte/Mphi (GM)-CSF and IL-4 (interleukin-4), only(More)
Crohn's disease (CD) and chronic ulcerative colitis (UC) are considered as two distinct forms of inflammatory bowel disease (IBD). In IBDs, the first clinical signs of disease begin typically between adolescence and the third decade of life (Andres & Friedman 1999; Baldassano & Piccoli 1999). CD is a non-specific granulomatous inflammatory disease affecting(More)
