   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian β-defensins AvBDs ; Avian gene expression; Host-pathogen interactions; Innate immunity; Mallard Anas platyrhynchos ; Myxovirus resistance gene Mx ; Retinoic acid inducible gene 1 RIG-I ; Avian β-defensins AvBD ; Genuttryck; Gräsand Anas platyrhynchos ; Immunförsvar; Immungener; Myxovirus resistant gene Mx ; Patogen; Retinoic acid inducible gene 1 RIG-I ; Ecology; Ekologi;

   Sammanfattning : This thesis comprises two sections, both of which explore eco-immunology of the innate immune system of mallards (Anas platyrhynchos). The innate immune system serves a pivotal role as the first line of defense against invading pathogens, and is comprised of physical and chemical barriers. LÄS MER

3. 2. Host-pathogen interactions during tick-borne flavivirus infection : pathogenesis, tropism and tools

   Författare :Ebba Rosendal; Anna K. Överby Wernstedt; Emma Nilsson; Jonathan D. Gilthorpe; Sonja M. Best; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tick-borne encephalitis virus; Langat virus; pathogenesis; type I interferons; central nervous system; neuroinflammation; structural proteins; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

   Sammanfattning : Tick-borne encephalitis virus (TBEV) is a neurotropic member of the genus Flavivirus. It may transmit to humans through the bite of an infected tick or consumption of unpasteurized dairyproducts, and causes tick-borne encephalitis (TBE). TBE constitutes a significant health burden in Eurasia, with more than 10,000 cases reported every year. LÄS MER

4. 3. Advancing portable, aqueous drug delivery to the human lung

   Författare :Torben Last; Göran Stemme; Niclas Roxhed; Claus-Michael Lehr; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Portable Inhaler; Biopharmaceuticals; Soft-mist inhaler; Transport vesicles; Microfluidic packaging; High-pressure microfluidics; aerosolization; cleanroom-free fabrication; drug delivery; micro-electromechanical systems MEMS ; Applied Medical Technology; Tillämpad medicinsk teknik;

   Sammanfattning : Lung disease profoundly impacts human health: many lung diseases are currently without cure and require continued treatment. Due to their ease of use and integration into the daily routine, portable inhalers are the preferred treatment option for patients. LÄS MER

5. 4. Regulation of lymphocyte activation and death

   Författare :Hanna Lindgren; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; N-substituted benzamides; apoptosis; NF-kB; NFAT; T cells; CD40L; serology; transplantation; Immunologi; serologi;

   Sammanfattning : T lymohocytes (T cells) and B lymphocytes (B cells) are important effector cells of the adaptive immune system. In response to infections, B cells are activated and produce antibodies against specific antigens. LÄS MER

7. 5. Helicobacter pylori infection in a mouse model: Development, optimization and inhibitory effects of antioxidants

   Författare :Xin Wang; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; bacteriology; Microbiology; mice; Helicobacter pylori; gastritis; lymphoma; antioxidant; diet; Th1 and Th2; cytokines; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Helicobacter pylori is a human pathogen strongly associated with chronic type B gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma. Our aims were to establish a mouse model of H. pylori infection, to study pathogenesis of gastritis and gastric cancer and to investigate new treatment strategies in this model. LÄS MER
