1. 1. Alpha-1-microglobulin, heme-binding protein, reductase and antioxidant

   Författare :Maria Allhorn; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reduction; inflammation; chronic ulcers; collagen; low density lipoproteins; Medicin människa och djur ; Medicine human and vertebrates ; antioxidation; heme; hemoglobin; alpha-1-microglobulin; lipocalin;

   Sammanfattning : This thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. LÄS MER

3. 2. Membrane traffic in neutrophils and neutrophil-like cells

   Författare :Susanne Bauer; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; membrane traffic; Hematologi; extracellular fluids; Haematology; Medicin människa och djur ; Medicine human and vertebrates ; CD177; extracellulära vätskor; PR3; phagocytosis; Streptococcus pyogenes; Infektioner; neutrophils;

   Sammanfattning : The neutrophil constitutes the first line of defence against invading organisms and its primary function is to recognize, phagocytose and kill intruding microorganisms. In this thesis, the membrane traffic in neutrophils and neutrophil-like cells was studied. Non-opsonised S. LÄS MER

4. 3. Inflammation, kinins, and kinin receptors

   Författare :Sara Bengtson; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Evidence is accumulating that the pathogenesis of many diseases is triggered by inappropriate inflammatory responses. These serious complications may occur when the tightly regulated inflammatory network is out of balance and it is now clear that this can eventually cause substantial harm to own cells and tissues.

5. 4. Molecular and microscopical analysis of pathogenic streptococci - studies on surface proteins interacting with human cells and extracellular matrix

   Författare :Marta Bober; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; streptococcal leucine rich repeat protein; M protein; collagen; keratinocytes;

   Sammanfattning : Association to specific host tissue structures allows pathogenic bacteria to establish an infection and facilitates the spread within its host. Interactions between bacterial surface structures and human proteins might determine the outcome of the infection. Streptococcus pyogenes (S. LÄS MER

7. 5. Streptococcus pyogenes secreted enzymes interacting with the human host

   Författare :Mattias Collin; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA fingerprinting; Streptococcus pyogenes; Clinical biology; immunoglobulins; Klinisk biologi; autoimmunity; endoglycosidase; cysteine proteinase; glycosylation;

   Sammanfattning : Streptococcus pyogenes is one of the most common bacteria infecting humans. One of the factors contributing to the disease-causing properties is the secreted streptococcal cysteine proteinase, SpeB, which degrades several host proteins in connective tissue and circulation.
