2. 1. Staphylococcal enterotoxin H - structure and function of a superantigen

   Author : Helen Pettersson; Lunds universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; TCR; staphylococcal enterotoxin H; MHC class II; superantigen; transplantation; Immunologi; serologi; serology;

   Abstract : The aim of this thesis was to characterise the biological functions of the superantigen staphylococcal enterotoxin H (SEH). Superantigens are highly immunostimulatory proteins, which crosslink T cells and antigen presenting cells (APCs). READ MORE

4. 2. The immunomodulatory function of staphylococcal superantigen on oral tolerance

   Author : Anna Stern; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oral tolerance; superantigen; hygiene hypothesis; staphylococcal enterotoxin;

   Abstract : Exposure to soluble proteins via the gut gives rise to systemic tolerance, a phenomenon called oral tolerance. Failure of oral tolerance results in allergy, a disease that has increased during the last decades in Western industrialized countries. The cause of this rapid increase is unknown. READ MORE

5. 3. Structural studies of metal-binding proteins revealing dynamic behaviour

   Author : Maria Håkansson; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Molekylär biofysik; Molecular biophysics; zinc; magnesium; superantigen; calbindin D9k; X-ray crystallography; staphylococcal enterotoxin; structure; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Abstract : The Mg2+ and Mn2+ structures of calbindin D9k have been determined and they reveal a conformational change compared to the structures of apo and (Ca2+)2-calbindin D9k. These findings are unique, since normally calcium and not magnesium is known to induce conformational changes of EF-hand proteins. READ MORE

6. 4. Development of Capacitive Biosensors for Monitoring of Bacterial Toxins and Other Biomolecules

   Author : Mahmoud Labib; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme-linked immunosorbent assay; self-assembled monolayers; competitive capacitive biosensing; cholera toxin; Capacitive biosensor; surface plasmon resonance; staphylococcal enterotoxin B; nanogold; human immunoglobulin G; glucose;

   Abstract : Sensing and quantification of biomolecules are becoming increasingly important in medical diagnostics, bioprocess technology and recently in homeland security. The majority of techniques currently employed to interrogate biomolecules require some type of radio-, enzymatic- or fluorescent-labeling. READ MORE

7. 5. Structural Basis of Immune Receptor Binding by Staphylococcal Superantigens

   Author : Karin Rödström; Medicinsk strukturbiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Superantigen; X-ray Crystallography; T cell receptor; Major histocompatibility complex;

   Abstract : Superantigens (SAgs) are toxins capable of inducing a massive immune response, leading to severe disease. They are secreted by the bacteria Staphylococcus aureus and Streptococcus pyogenes, which produce the staphylococcal enterotoxins and streptococcal pyogenic exotoxins, respectively. READ MORE
