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

   Author : Dan Dou; Robert Daniels; Martin Schwemmle; Stockholms universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Influenza Neuraminidase : Conserved features of a rapidly mutating virus

   Author : Henrik Östbye; Pia Ädelroth; Anice Lowen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; influenza; virology; neuraminidase; biokemi; Biochemistry;

   Abstract : Influenza A viruses (IAVs) of the H1N1 and H3N2 serotypes are the major cause of seasonal influenza epidemics. IAVs are labeled based on the antigenic properties of the two surface glycoproteins and main antigens: hemagglutinin (HA/H) and neuraminidase (NA/N). READ MORE

5. 3. Influenza Neuraminidase : Novel mechanisms of influenza NA that enable adaptation and promote diversification

   Author : Hao Wang; Robert Daniels; Colin Russell; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Influenza; IAV; neuraminidase; transmembrane domain; the central Ca2 binding site; heterotetrameric formation; viral incorporation; evolution; adaptation; diversification; Biochemistry; biokemi;

   Abstract : Influenza A viruses (IAVs) are one of the most common human respiratory pathogens and are largely responsible for the seasonal influenza epidemics that cause mild to severe disease. The two IAV glycoproteins, hemagglutinin (HA or H) and neuraminidase (NA or N), serve as the major surface antigens and also are the main determinants of infectivity, pathogenicity and transmissibility.

6. 4. Viruses on the wing : evolution and dynamics of influenza A virus in the Mallard reservoir

   Author : Michelle Wille; Jonas Waldenström; Timm Harder; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Co-infections; Ecology; Epidemiology; Evolution; Host-Parasite Interactions; Immunity; Influenza A Virus; Mallard; Phylogeny; Virology; Waterfowl; Wild Birds; Wildlife Disease; Zoonotisk ekologi; Zoonotic Ecology;

   Abstract : This thesis explores the evolution of avian influenza A viruses (IAV), as well as host-pathogen interactions between these viruses and their main reservoir host, the Mallard (Anas platyrhynchos). IAV is a genetically diverse, multi-host virus and wild birds, particularly dabbling ducks, are the natural reservoir. READ MORE

7. 5. Influenza neuraminidase assembly : Evolution of domain cooperativity

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

   Abstract : 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). READ MORE
