Since leukocyte adhesion to endothelial cells is crucial for extravasation of leukocytes to sites of inflammation, inhibition of cell-cell adhesion has been suggested as a means to achieve selective modulation of the immune system. We have, using a static in vitro adhesion assay involving adhesion
Sandhoff disease (SD) is a lysosomal β-hexosaminidase (Hex) deficiency involving excessive accumulation of undegraded substrates, including GM2 ganglioside, and progressive neurodegeneration. Macrophage inflammatory protein-1α (MIP-1α) is a crucial factor for microglia-mediated neuroinflammation in
BACKGROUND
Lipoatrophy modestly improves when the thymidine analogue nucleoside reverse transcriptase inhibitor (tNRTI) is removed. In vitro, uridine (NucleomaxX(®); Pharma Nord, Vojens, Denmark) reversed tNRTI mitochondrial toxicity.
METHODS
All patients had lipoatrophy on a tNRTI-containing
Nucleosides like adenosine, uridine and their nucleotide derivatives (e.g. ATP and UTP) play important roles in many cellular functions, sometimes by acting as signalling molecules through binding to specific P2 nucleotide receptors. P2 receptors are subdivided into P2X and P2Y subfamilies, the
BACKGROUND
The immuno-modulatory properties of nucleotides such as adenosine or inosine, have been described extensively. Recently, the nucleoside uridine and its analogue 4-thiouridine have gained attention for their protective role in acute lung inflammation.
OBJECTIVE
In this study, we
It is very well established that purinergic signaling plays a relevant role in vascular physiology and pathophysiology. Recently, a new purinoceptor agonist uridine adenosine tetraphosphate (Up(4)A) has been identified as a highly potent endothelial-derived contracting factor (EDCF). The purpose of
In this study, we examined the effects of uridine on plasma cytokine levels, heat shock protein (HSP) 72 expression, and nuclear factor (NF)-κB signaling in spleen lymphocytes after exposure of male BALB/c mice to Escherichia coli lipopolysaccharide (LPS). Mice were treated with uridine (30 mg/kg
BACKGROUND
Pulmonary fibrosis is a progressive disease with only few treatment options available at the moment. Recently, the nucleoside uridine has been shown to exert anti-inflammatory effects in different animal models, e.g. in acute lung injury or bronchial asthma.
METHODS
Therefore, we
Adenosine and uridine triphosphate (ATP and UTP) can act as extracellular signalling molecules, playing important roles in vascular biology and disease. ATP and UTP acting via the P2Y2-receptor have, for example, been shown to regulate endothelial dilatation, inflammation and angiogenesis. MicroRNAs
Uridine diphosphate glucuronosyltransferase (UGT) was identified as an antigenic target in a subgroup of liver-kidney microsomal autoantibodies and was termed LKM-3. To evaluate the nature of LKM-3 antibodies, we screened sera from 80 untreated patients with autoimmune hepatitis (AIH) type 1 and 2,
To investigate the role of IFN-gamma in the immunopathogenesis of inflammatory bowel disease (IBD), severe combined immunodeficient (SCID) mice were transplanted with in vitro activated CD4+ T cells from either wild-type (WT) or IFN-gamma-deficient (IFN-gammaKO) BALB/c mice. In vitro, the two types
