  1. 1. Control of Quasi-Equivalence in Virus Capsids

    Författare :Charlotte Helgstrand; B. V. Venkataram Prasad; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; crystallography; bacteriophage; virus; RNA; capsid; quasi-equivalence; assembly; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Many T=3 plant and insect viruses use a molecular switch in form of order/disorder of a segment of the polypeptide chain to regulate the quasi-equivalent contacts. The structure of a mutant of the T=3 capsid of bacteriophage fr confirms that this virus and other members of the Leviviridae family lack a switch mechanism. LÄS MER

  3. 2. Influenza neuraminidase assembly : Evolution of domain cooperativity

    Författare :Diogo da Silveira Vieira da Silva; Robert Daniels; Ron Fouchier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Influenza; neuraminidase; assembly; transmembrane domain; evolution; Biochemistry; biokemi;

    Sammanfattning : Influenza A virus (IAV) is one of the most common viruses circulating in the human population and is responsible for seasonal epidemics that affect millions of individuals worldwide. The need to develop new drugs and vaccines against IAVs led scientists to study the main IAV surface antigens hemagglutinin (HA) and neuraminidase (NA). LÄS MER

  4. 3. Influenza A Virus : Spatial analysis of influenza genome trafficking and the evolution of the neuraminidase protein

    Författare :Dan Dou; Robert Daniels; Martin Schwemmle; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Influenza A virus; IAV; neuraminidase; NA; IAV genome trafficking; viral entry; viral replication; co-infection; antigenic drift; antigenic shift; NA assembly; transmembrane domain; evolution; Biochemistry; biokemi;

    Sammanfattning : Influenza A viruses (IAVs) are a common infectious agent that seasonally circulates within the human population that causes mild to severe acute respiratory infections. The severity of the infection is often related to how the virus has evolved with respect to the pre-existing immunity in the population. LÄS MER

  5. 4. Assembly and entry mechanisms of Semliki Forest virus

    Författare :Bernd Uwe Barth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Semliki Forest virus; virus assembly; protein oligomerization; virus budding;

    Sammanfattning : The genomes of enveloped viruses are packaged into a core or nucleocapsid (NC) which is surrounded by a lipid membrane with spike proteins. These viruses mature by budding at a membrane of the host cell, usually the plasma membrane (PM), and penetrate into new ones by a virus-host membrane fusion event. LÄS MER

  7. 5. Characterizing important flavivirus-host interactions : Replication, assembly, restriction factors and vaccine development

    Författare :Pham Tue Hung Tran; Magnus Johansson; Wessam Melik; Naveed Asghar; Sören Andersson; Laurent Chatel-Chaix; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Flaviviruses; virus-host cell interaction; lunapark; ESCRT; ALIX; CHMP4A; ISG15; TRIMs; replicon virus-like particles; vaccine;

    Sammanfattning : The genus Flavivirus (family Flaviviridae) consists of important zoonotic viruses that cause morbidity and mortality worldwide. These viruses are enveloped and have a positive-sense single-stranded RNA genome encoding a polyprotein. LÄS MER
