1. 1. 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

3. 2. Rift Valley fever : consequences of virus-host interactions

   Författare :Maria Baudin; Magnus Evander; Clas Ahlm; Göran Bucht; Tomas Bergström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rift Valley fever; Rift Valley fever virus; viral haemorrhagic fever; miscarriage; entry; charge; carbohydrates; high-throughput screening; antiviral; cell-based assay; medicinsk virologi; Medical Virology;

   Sammanfattning : Rift Valley fever virus (RVFV) is a mosquito-borne virus which has the ability to infect a large variety of animals including humans in Africa and Arabian Peninsula. The abortion rate among these animals are close to 100%, and young animals develop severe disease which often are lethal. LÄS MER

4. 3. Infection, early entry events and replication processes of picornaviruses

   Författare :Helena Vandesande; A. Michael Lindberg; Jorma Hinkula; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Picornavirus; enterovirus; cardiovirus; echovirus; rhinovirus; coxsackievirus B; Saffold virus; early entry; replication; gastroenteritis; aseptic meningitis.; Virology; Virologi;

   Sammanfattning : The Picornaviridae is a large and diverse family of small RNA viruses, several of which have exhibited a distinct clinical and socioeconomic impact on human society. While many infections are asymptomatic, some members of this virus family have the potential to cause severe disease, including, but not limited to, poliomyelitis, myocarditis, meningitis, and foot-and-mouth disease.

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. Pathogen entry mechanisms and endocytic responses to plasma membrane damage

   Författare :Lars Nygård Skalman; Richard Lundmark; Kristian Riesbeck; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Endocytosis; plasma membrane; pathogens; virus; bacterial membrane vesicles; Helicobacter pylori; adenovirus 37; listeriolysin O; pore-forming toxins; membrane repair;

   Sammanfattning : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. LÄS MER
