Joint host-pathogen genomic analysis identifies hepatitis B virus mutations associated with human NTCP and HLA class I variation

Jacques Fellay, Bruno Emanuel Ferreira De Sousa Correia, Zhi Ming Xu, Andreas Scheck, Dylan Lawless, Olivier Noël Marie Naret, Arne Schneuing, David Gfeller, Thomas Junier, Sina Rüeger

Evolutionary changes in the hepatitis B virus (HBV) genome could reflect its adaptation to host -induced selective pressure. Leveraging paired human exome and ultra -deep HBV genome-sequencing data from 567 affected individuals with chronic hepatitis B, we ...

Background and Aims:The clinical spectrum of human infection by HEV ranges from asymptomatic to severe acute hepatitis. Furthermore, HEV can cause diverse neurological manifestations, especially Parsonage-Turner syndrome. Here, we used a large-scale human ...

Hosts and pathogens are involved in a long-standing evolutionary arms race characterized by successive rounds of evolution. Specifically, while hosts evolve resistance against infections, pathogens adapt to re-establish virulence. Since the signatures of t ...

Mycobacterium leprae, the causative agent of leprosy, is an unculturable bacterium with a considerably reduced genome (3.27 Mb) compared to homologues mycobacteria from the same ancestry. In 2001, the genome ofM. lepraewas first described and subsequently ...

In developing countries, the waterborne transmission of hepatitis E virus (HEV), caused by HEV genotypes 1 (HEV-1) and 2 (HEV-2), leads to the onset of large recurrent outbreaks. HEV infections are of particular concern among pregnant women, due to very hi ...

Human genomics of acute liver failure due to hepatitis B virus infection: An exome sequencing study in liver transplant recipients

Jacques Fellay, Christian Hammer, Nimisha Chaturvedi, Petar Scepanovic, Samira Asgari

Acute liver failure (ALF) or fulminant hepatitis is a rare, yet severe outcome of infection with hepatitis B virus (HBV) that carries a high mortality rate. The occurrence of a life-threatening condition upon infection with a prevalent virus in individuals ...

Genetic polymorphism in the interferon lambda (IFN-lambda) region is associated with spontaneous clearance of hepatitis C virus (HCV) infection and response to interferon-based treatment. Here, we evaluate associations between IFN-l polymorphism and HCV va ...

Population density and water balance influence the global occurrence of hepatitis E epidemics

Stéphane Joost, Anna Carratala Ripolles

In developing countries, the waterborne transmission of hepatitis E virus (HEV), particularly the genotypes 1 and 2, leads to the onset of large recurrent outbreaks. In order to identify the geographical regions at higher risk of HEV epidemics and the cond ...

Hepatitis E virus (HEV) is a positive-strand RNA virus encoding 3 open reading frames (ORF). HEV ORF3 protein is a small, hitherto poorly characterized protein involved in viral particle secretion and possibly other functions. Here, we show that HEV ORF3 p ...

Integration of the role of climate in the spatial modeling of waterborne hepatitis E virus

Stéphane Joost, Anna Carratala Ripolles

Hepatitis E virus (HEV) is among the major causes of acute viral hepatitis worldwide. In developing countries, HEV infections are caused by genotypes 1 and 2, due to consumption of contaminated water. Large and recurrent outbreaks of HEV occur in specific ...
