  2. 1. Eco-immunological studies of innate immunity in Mallards (Anas platyrhynchos)

    Author : Anu S. Helin; Jonas Waldenström; Edwin Veldhuizen; Linnéuniversitetet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Ebba Rosendal; Anna K. Överby Wernstedt; Emma Nilsson; Jonathan D. Gilthorpe; Sonja M. Best; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Torben Last; Göran Stemme; Niclas Roxhed; Claus-Michael Lehr; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Regulation of lymphocyte activation and death

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

    Abstract : 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. READ MORE

  7. 5. MHC polymorphism and host-pathogen interactions: The case of Borrelia in its reservoir host, the bank vole Myodes glareolus

    Author : Kristin Scherman; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Host-pathogen interaction; Negative frequency dependent selection; Myodes glareolus; Borrelia;

    Abstract : The major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS).
