In vivo RNAi screening identifies new regulators of liver regeneration

Innovation in science

2011-04-02

(Press-News.org) This study establishes a unique system to perform in vivo RNAi screens for genetically dissecting the cellular signalling networks that regulate hepatocyte proliferation during chronic liver damage.1

Functional in vivo validation studies show that stable knockdown of the candidate gene by different shRNAs can significantly increase the repopulation efficiency of mouse hepatocytes and also increase the regenerative capacity of chronically damaged mouse livers.

Such detailed understanding of the signalling pathways involved in hepatocyte proliferation control holds the promise of new therapies to increase the hepatic regenerative potential for future new strategies in HCC treatment.

First vaccine for viral hepatitis C could become a reality

2011-04-02

Berlin, Germany, Friday 01 April 2011: Early data from phase I trials of an HCV vaccine presented today at the International Liver CongressTM show encouraging results, with high immunogenicity and good safety profile.1,2 In the first study1, a therapeutic T-cell vaccine, based on novel adenoviral vectors was used on a small population of treatment naive patients with chronic genotype 1 HCV infection. Intra-muscular vaccination was administered 2 or 14 weeks into a 48-week course of treatment with Peg-IFNa2a/ribavirin. 50% of vaccinated patients had CD4+ and CD8+ HCV specific ...

The future looks bright for HCV patients who have failed to respond to current treatments

2011-04-02

Berlin, Germany, Friday 1st April 2011: Highly anticipated data from a number of clinical trials presented for the first time at the International Liver CongressTM confirmed that a range of new proteases inhibitors will help treat patients who have previously failed therapy for the treatment of chronic hepatitis C.1,2,3,4,5 The treatments have been tested for efficacy and safety in combination with PegIFN-alpha and ribavirin in patients that have previously failed treatment (either non-responder or relapse). Following different treatment and dosing, all of the trials ...

Fratricide of HBV-specific CD8 T cells by NK cells mediated through the TRAIL pathway

2011-04-02

A new study presented today at the International Liver CongressTM shows a novel pathway where activated natural killer (NK) cells expressing death ligands may excessively down-modulate the antiviral immune response in chronic HBV patients.1 Blocking the TNF-related apoptosis-inducing ligand (TRAIL) pathway partially reconstitutes HBV-specific T cells, suggesting that these cells are vulnerable to NK cell-mediated apoptosis through this death ligand pathway. NK cells are one of the main effectors of the innate immune response that plays a key role in containing intracellular ...

Got a craving for fast food? Skip the coffee, study says

2011-04-02

Eating a fatty fast food meal is never good for you, but washing that meal down with a coffee is even worse, according to a new University of Guelph study. Researcher Marie-Soleil Beaudoin has discovered not only that a healthy person's blood sugar levels spike after eating a high-fat meal, but that the spike doubles after having both a fatty meal and caffeinated coffee – jumping to levels similar to those of people at risk for diabetes. "The results tell us that saturated fat interferes with the body's ability to clear sugars from the blood and, when combined with ...
