BACKGROUND Recent experimental approaches have unraveled essential migratory and functional differences of monocyte subpopulations in mice. In order to possibly translate these findings into human physiology and pathophysiology, human monocyte subsets need to be carefully revisited in health and disease. In analogy to murine studies, we hypothesized that(More)
BACKGROUND Interleukin-8 (IL-8, CXCL8) is a potent chemoattractant for neutrophils and contributes to acute liver inflammation. Much less is known about IL-8 in chronic liver diseases (CLD), but elevated levels were reported from alcoholic and hepatitis C-related CLD. We investigated the regulation of IL-8, its receptors CXCR1 and CXCR2 and possible IL-8(More)
BACKGROUND Inflammation is a major factor for the progression of chronic liver diseases. Interactions between urokinase plasminogen activator (uPA) and its receptor (uPAR) have been functionally linked to hepatic inflammation and fibrosis in mice. High serum concentrations of soluble uPAR (suPAR) are suggested to reflect activated immune cells. AIMS We(More)
BACKGROUND Monocyte-derived macrophages critically perpetuate inflammatory responses after liver injury as a prerequisite for organ fibrosis. Experimental murine models identified an essential role for the CCR2-dependent infiltration of classical Gr1/Ly6C(+) monocytes in hepatic fibrosis. Moreover, the monocyte-related chemokine receptors CCR1 and CCR5 were(More)
BACKGROUND The soluble interleukin-2 receptor (sIL-2R, sIL2R, sTAC, sCD25) is a reliable biomarker for disease activity in inflammatory disorders such as sarcoidosis. Based on the essential pathogenic role of inflammation for progression of liver diseases, we hypothesized that sIL-2R might be an indicator of inflammatory cell activation and disease severity(More)
BACKGROUND/AIMS Experimental liver injury models have indicated that natural killer (NK) cells are critical regulators of inflammation and fibrosis. However, data on NK cells and subsets in patients with liver diseases are limited. We thus comprehensively characterized peripheral and hepatic NK cell subsets in patients with chronic liver diseases (CLDs) of(More)
