  1. 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

  2. 2. Thymic studies. Investigations into the effects of childhood thymectomy, and characterization of thymic B cells and Hassall's corpuscles

    Author : Christina Lundqvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thymus; thymectomy; TCR; B cells; APC; Hassall s corpuscles; AIRE;

    Abstract : This thesis focuses on the human thymus, a primary lymphoid organ responsible for the maturation of T cells. Progenitors arrive from the bone marrow and start to randomly assemble their T cell receptor (TCR) followed by a thorough selection process in which the TCR is tested for functionality and autoreactivity.

  3. 3. Interplay between superantigens and immunoreceptors

    Author : Karin Lindkvist; Medicinsk strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; serology; Immunology; TCR; MHC class II; X-ray crystallography; superantigen; staphylococcal enterotoxin; Biofysik; transplantation; Immunologi; serologi; Biophysics;

    Abstract : This thesis deals with the interactions between superantigens and their receptors. Superantigens are proteins that are secreted by various bacteria, such as Staphylococcus aureus and Streptococcus pyogenes. Superantigens are able to cross-link T cells and antigen presenting cells by binding to the T cell receptor (TCR) and MHC class II. READ MORE

  4. 4. Dysregulated mucosal immune responses in microscopic colitis patients

    Author : Sezin Günaltay; Elisabeth Hultgren-Hörnquist; Olof Hultgren; Nils Nyhlin; Allan Mowat; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microscopic colitis; collagenous colitis; lymphocytic colitis; TLR; chemokine; chemokine receptor; IL-37; TCR; Immunology; Immunologi; Biomedicin; Biomedicine;

    Abstract : Microscopic colitis (MC), comprising collagenous colitis (CC) and lymphocytic colitis (LC) is a common cause of chronic watery diarrhea. The diagnosis relies on typical histopathological changes observed upon microscopic examination. READ MORE

  5. 5. Regulation of activation of NF-κB by Calmodulin in T-lymphocytes

    Author : Sreenivasa Rao Oruganti; Thomas Grundström; Eva Sverinson; Umeå universitet; []
    Keywords : Calcium; Calmodulin; CaMKII; TCR; Bcl10; NF-κB;

    Abstract : Nuclear factor kappa B (NF-kB) is a widely expressed family of transcription factors that are involved in a diverse number of processes. These include inflammation or differentiation, survival or apoptosis, and proliferation or cell cycle arrest. READ MORE
