A novel calmodulin-like protein from the liver fluke, Fasciola hepatica.

An 18.2 kDa protein from the liver fluke, Fasciola hepatica has been identified and characterised. The protein shows strongest sequence similarity to egg antigen proteins from Schistosoma mansoni, Schistosoma japonicum and Clonorchis sinensis.

Live-cell visualization of transmembrane protein oligomerization and membrane fusion using two-fragment haptoEGFP methodology.

Protein interactions play key roles throughout all subcellular compartments. In the present paper, we report the visualization of protein interactions throughout living mammalian cells using two oligomerizing MV (measles virus) transmembrane glycoproteins, the H (haemagglutinin) and the F (fusion) glycoproteins, which mediate MV entry into permissive cells. BiFC (bimolecular fluorescence complementation) has been used to examine the dimerization of these viral glycoproteins.

The use of antiendotoxin peptides in obstructive jaundice endotoxemia.

Background: Two novel antiendotoxin peptides, P6 and C1, may reduce the inflammatory response. This study aimed to determine the effect of endotoxin on hepatic cytokine response and to assess P6 and C1-related attenuation of the proinflammatory response to endotoxemia, in experimental biliary obstruction.

Materials And Methods: 15 Male Wistar rats were randomized to one of three groups: bile duct ligation (BDL)+P6 (n=5), BDL+C1 (n=5), and BDL+no peptide (n=5).

Liver fluke β-tubulin isotype 2 binds albendazole and is thus a probable target of this drug.

Albendazole is a benzimidazole drug which can be used to treat liver fluke (Fasciola hepatica) infections. Its mode of action is believed to be the inhibition of microtubule formation through binding to β-tubulin. However, F.

Differential preservation of lipopolysaccharide-induced chemokine/cytokine expression during experimental pancreatitis-associated organ failure in rats shows a regulatory expressed phenotype.

Background: Altered lipopolysaccharide (LPS)-responsiveness is a key feature of acute pancreatitis (AP)-associated multiple organ failure (AP-MOF) in rats and humans.

Aim: To determine the differential expression of 16 cytokines and chemokines in response to delayed LPS administration in established experimental AP-MOF in rats.

Methods: In a cubic factorial group design (12 groups, n = 6 rats/group), 0, 6 and 30 microg/kg Escherichia coli 0111:B4 LPS was administered intra-arterially, 18 h into experimental AP-MOF or sham laparotomy.
