Host-Pathogen Interactions Through the Genomic Lens

Zhi Ming Xu

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 ...

Induction of a strong and long-lasting neutralizing immune response by dPreS1-TLR2 agonist nanovaccine against hepatitis B virus

Myriam Isabelle Lamrayah

Hepatitis B virus remains a major medical burden with more than 250 million chronically infected patients worldwide and 900,000 deaths each year, due to the disease progression towards severe complications (cirrhosis, hepatocellular carcinoma). Despite the ...

Inborn errors of type I interferon immunity in patients with symptomatic acute hepatitis E

Jacques Fellay, Ali Saadat Varnosfaderanii

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 ...

Phylogenetic estimation of the viral fitness landscape of HIV-1 set-point viral load

Jacques Fellay

Set-point viral load (SPVL), a common measure of human immunodeficiency virus (HIV)-1 virulence, is partially determined by viral genotype. Epidemiological evidence suggests that this viral property has been under stabilising selection, with a typical opti ...

Genomic Diversity of Torque Teno Virus in Blood Samples from Febrile Paediatric Outpatients in Tanzania: A Descriptive Cohort Study

Mary-Anne Hartley

Torque teno virus (TTV) is considered to be an ubiquitous member of the commensal human blood virome commonly reported in mixed genotype co-infections. This study investigates the genomic diversity of TTV in blood samples from 816 febrile Tanzanian childre ...

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 ...

Adaptation of hepatitis C virus to interferon lambda polymorphism across multiple viral genotypes

Jacques Fellay, Nimisha Chaturvedi

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), 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 ...

Detection of dicistroviruses RNA in blood of febrile Tanzanian children

Mary-Anne Hartley, Thomas Junier

Fever is the leading cause of paediatric outpatient consultations in Sub-Saharan Africa. Although most are suspected to be of viral origin, a putative causative pathogen is not identified in over a quarter of these febrile episodes. Using a de novo assembl ...

The memristive effect as a novelty in drug monitoring

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki, Nima Aliakbarinodehi

Nanoscale devices exhibiting memristive properties show great potential in a plethora of applications. In this work, memristive nanowires are presented for the first time as ideal candidates for absolutely novel, ultrasensitive, highly specific and selecti ...

Role of APOBEC3F Gene Variation in HIV-1 Disease Progression and Pneumocystis Pneumonia

Jacques Fellay, Christian Axel Wandall Thorball, Istvan Bartha

Human APOBEC3 cytidine deaminases are intrinsic resistance factors to HIV-1. However, HIV-1 encodes a viral infectivity factor (Vif) that degrades APOBEC3 proteins. In vitro APO-BEC3F (A3F) anti-HIV-1 activity is weaker than A3G but is partially resistant ...

Efficient voltammetric discrimination of free bilirubin from uric acid and ascorbic acid by a CVD nanographite-based microelectrode

Giovanni De Micheli, László Forró, Sandro Carrara, Arnaud Magrez, Irene Taurino

We report a novel electrochemical sensor based on nanographite grown on platinum microelectrodes for the determination of bilirubin in the presence of normal concentrations of albumin. The albumin is a protein with an intrinsic ability to bind the bilirubi ...

Host miRNA regulation of human cytomegalovirus immediate early protein translation promotes viral latency

Jiri Vanicek

Reactivation of human cytomegalovirus (HCMV) is a significant cause of disease and death in immunocompromised patients underscoring the need to understand how latency is controlled. Here we demonstrate that HCMV has evolved to utilize cellular miRNAs in ce ...

Ablation of the Tumor Suppressor Histidine Triad Nucleotide Binding Protein 1 is Protective Against Hepatic Ischemia/Reperfusion Injury

The identification of cellular pathways capable of limiting ischemia/reperfusion (I/R) injury remains a frontier in medicine, and its clinical relevance is urgent. Histidine triad nucleotide binding protein 1 (HINT1) is a tumor suppressor that influences a ...
