1. 1. 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

3. 2. Bird-parasite interactions : Using Sindbis virus as a model system

   Författare :Karin M. Lindström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Carduelis chloris; Sindbis virus; host-parasite interaction; ornament; social dominance; testosterone; sexual selection; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; populationsbiologi; Population Biology;

   Sammanfattning : This thesis focuses on the evolutionary interactions between birds and a parasite, the mosquito-borne Sindbis virus (Togaviridae, Alphavirus). In conclusion, the results show that the Sindbis virus is widespread among birds, and that the fitness of infected hosts may be reduced by the virus. LÄS MER

4. 3. Avian Influenza Virus : Deciphering receptor interactions and their role in interspecies transmission

   Författare :Per Eriksson; Patrik Ellström; Björn Olsen; Josef D. Järhult; Åke Lundkvist; Jonas Waldenström; Hans-Dieter Klenk; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birds; glycobiology; glycovirology; host range; mixing vessel; virus attachment; Medical Virology; Medicinsk virologi;

   Sammanfattning : Influenza A virus (IAV) annually infects approximately 5–15 % of the human population, causing ~500,000 deaths globally. Novel IAVs have emerged and spread pandemically in the human population, but have over time established endemic circulation with reduced pathogenicity causing seasonal influenza. The natural reservoir of IAVs is wild waterfowl. LÄS MER

5. 4. Host-Virus Interactions in Asthma and COPD

   Författare :Cristopher McCrae; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; COPD; Exacerbation; Virus; Interferon;

   Sammanfattning : Asthma and chronic obstructive pulmonary disease (COPD) are associated with periods of worsened symptoms, known as exacerbations. Severe exac-erbations can result in hospitalisation, irreversible decline of the disease and sometimes death. Thus, exacerbations are a major cause of morbidity, mortality and healthcare cost.

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
