  2. 1. Physics of Viral Infectivity: Energetics of Genome Ejection

    Author : Meerim Jeembaeva; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microfluidics.; differential scanning calorimetry; capsid; Key words: phage; osmotic suppression; DNA ejection; isothermal titration calorimetry; enthalpy;

    Abstract : All viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. READ MORE

  4. 2. Hepatitis C virus. Aspects on natural history, antibody response, and viral quantification

    Author : Martin Lagging; Göteborgs universitet; []
    Keywords : Hepatitis C virus; nosocomial infection; pseudotyped virus; fibrosis; viral quantification;

    Abstract : Hepatitis C virus (HCV) is the major cause of parenterally transmitted non-A, non-B hepatitis, and is associated with chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Despite the screening of blood products nosocomial spread of HCV continues to occur. READ MORE

  5. 3. Altering HIV-1 envelope glycoprotein maturation and its effects on viral infectivity

    Author : Alenka Jejcic; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1;

    Abstract : HIV-1 is dependent on its envelope glycoprotein (Env) to initiate infection. Env binds to cellular receptors and mediate the following fusion of the viral envelope with the cell plasma membrane. READ MORE

  6. 4. Viral Loop Dynamics in Temperate and Polar Freshwaters

    Author : Christin Säwström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; akvatisk ekologi; aquatic ecology; marine biology; Hydrobiology; temperate; polar; freshwaters; nutrient limitation; bacterial mortality; lysogeny; dissolved organic carbon; humic; Arctic; Antarctic; Bacteria; Virus; limnology; Marinbiologi; limnologi;

    Abstract : All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. READ MORE

  7. 5. Interaction-mediating sequences within class I viral fusion glycoproteins : their roles in viral infection and in applications

    Author : Simin Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Class I viral fusion glycoproteins facilitate fusion of the viral envelope with cell membranes and entry of the virus into the cell, through extensive short sequence-specific interactions. Regions mediating these interactions include the N-terminal hydrophobic fusion peptide, a pair of extended 4,3-hydrophobic heptad repeats (HRs), a membrane-active membrane proximal external region (MPER), a hydrophobic transmembrane domain and the cytoplasmic tail region.
