  2. 1. Genetic variability of hepatitis B virus in chronic infection

    Author : Charles Hannoun; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; mutation; genotype; phylogeny; ; Recombination; coinfection; interferon; response;

    Abstract : Chronic hepatitis B is a major health problem, and may lead to cirrhosis and hepatocellular carcinoma. The liver damage in hepatitis B virus (HBV) infection is considered to be a result of the immune response, and not a cytopathic effect of the virus itself. READ MORE

  4. 2. Geographic and genetic diversity of hepatitis B

    Author : Erik Alestig; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; genotype; phylogeny; molecular epidemiology; sequence analysis; mutation;

    Abstract : Hepatitis B Virus (HBV) infection is a global health problem and may lead to chronic hepatitis, liver cirrhosis and hepatocellular cancer. The ability of HBV to adapt to the host environment by genetic variation has lead to the evolution of 8 established (A-H) and 2 putative genotypes (I-J), each corresponding to a rather well-defined geographical distribution.

  5. 3. The hepatitis B virus – Insights into genetic variability, evolution and Bayesian phylogeographic inference

    Author : Mikael Ingman; Malmö Klinisk virologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatit B; evolutionsbiologi; fylogeni; Hepatitis B; evolutionary dynamics; Phylogeography;

    Abstract : In terms of genome size, the hepatitis B virus is the smallest virus known to infect humans and its compactness with multiple overlapping reading frames puts restraints on the emergence of mutations. In the papers included in this thesis we aimed to investigate genetic variation within the precore and core promoter region and to describe the origin, spread and diversification of HBV genotype A.

  6. 4. Molecular epidemiology of hepatitis A and hepatitis B virus in central America

    Author : Patricia Arauz-Ruiz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The genetic variability was determined for hepatitis A virus (HAV) and hepatitis B virus (HBV) strains from cases of acute and chronic hepatitis in Central America (CA). The genetic relatedness was established for the' strains to strains from other parts of the world. READ MORE

  7. 5. Development of a therapeutic vaccine against the hepatitis C virus

    Author : Gustaf Ahlén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HCV; NS3; DNA vaccine; electroporation;

    Abstract : The hepatitis C virus (HCV) infection is a major cause of liver disease and it is estimated that 170 million people worldwide are chronically infected by HCV. There are no protective or curable vaccines available for HCV, however treatment consisting of interferon-α and ribavirin is curative in 45-75% of the chronic infected patients, depending on the viral genotype.
