  1. 1. Mucosal Vaccination Using Polyacryl Starch Microparticles as Adjuvant with Salmonella enteritidis as a Model Pathogen

    Författare :Lena Strindelius; Ingvar Sjöholm; Mary Jo Wick; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; mucosal vaccination; polyacryl starch microparticles; salmonella enteritidis; flagellin; fimbriae; rCTB; LPS; Ussing chamber; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Sammanfattning : Polyacryl starch microparticles have been developed as a new mucosal vaccine adjuvant intended for use in oral vaccination. The main objectives of this thesis were to evaluate the efficacy of these polyacryl starch microparticles and to study their uptake through mucosal tissues. LÄS MER

  3. 2. Toll-like receptors (TLRs) and inflammatory bone modeling

    Författare :Ali Kassem; Ulf Lerner; Pernilla Lundberg; Pedro Souza; Timothy Arnett; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toll-like receptor; osteoclast; osteoblast; bone resorption; bone formation; P. gingivalis; S. aureus; flagellin.;

    Sammanfattning : Patients with inflammatory or infectious conditions such as periodontitis, peri-implantitis, osteomyelitis, rheumatoid arthritis, septic arthritis and loosened joint prosthesis display varying severity of destruction in the adjacent bone tissue. Bone loss in inflammatory diseases is considered a consequence of cytokine induced RANKL and subsequent enhanced osteoclast formation. LÄS MER

  4. 3. Host control of intracellular bacterial infections

    Författare :Emma Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Listeria monocytogenes; CD44; flagellin; Chlamydia pneumoniae; TLR; NOD; IFNalpha beta; IFN-gamma;

    Sammanfattning : In this thesis various immune mechanisms regulating control of infections with the intracellular bacteria Listeria monocytogenes and Chlamydia pneumoniae have been studied. These bacteria infect macrophages in which they can successfully grow. However, macrophages are potent killers of intracellular bacteria. LÄS MER

  5. 4. Role of c-di-GMP signalling in bacterial-host interactions

    Författare :Agaristi Lamprokostopoulou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bacteria have various ways to sense environmental signals and to adapt their behavior and physiology through different signaling systems. Secondary messenger signaling, amplified by enzymatic activity, rapidly transmits a signal in the cell, resulting in allosteric functional control. LÄS MER

  7. 5. Characterization of IgY for Oral Immunotherapy and Prevention of Pseudomonas aeruginosa Infections in Cystic Fibrosis Patients

    Författare :Elin Nilsson; Anders Larsson; Jane Burns; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical chemistry; Klinisk kemi; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Chicken antibodies, commonly referred to as IgY, have several properties that make them suitable for oral treatment of infections and there is essentially no risk for development of resistance. The overall aims of this thesis were to investigate Anti-Pseudomonas IgY as prophylaxis against infections with Pseudomonas aeruginosa for cystic fibrosis (CF) patients and to characterize the antibody treatment.
