1. 11. Glucocorticoid in T cell differentiation

   Författare :Yintong Xue; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Thymocytes differentiate into mature T cells with an immunological restriction for self major histocompatibility complex (MHC) antigens. Cells that do not recognize self MHC expressed on thymic epithelial cells (TEC) die by a rapid induction of apoptosis (default selection). LÄS MER

3. 12. Regulatory mechanisms controlling T cell activity

   Författare :Anette Sundstedt; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; T cell superantigen anergy interleukin-2 transcription factor cytotoxicity; serology; Immunology; Immunologi; serologi;

   Sammanfattning : This thesis is based on work studying the immunoregulatory mechanisms that govern the balance between activation and inactivation of T lymphocytes. Most of the work has been carried out in an experimental system using a T cell receptor (TCR-Vb3) transgenic mouse strain to obtain a homogenous T-cell population and utilizing the properties of bacterial superantigens to induce T cell responses and unresponsiveness in vivo.

   Sammanfattning : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. LÄS MER

5. 14. Aspects of T cell development contributing to autoimmunity

   Författare :Maria Carlsén; Diabetes - immunovirologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FTOC; T cell development; Type 1 diabetes; p53; Insulin; NOD; Negative selection; TGF-β; Tolerance; Thymus; Conditional cre lox knock out; Autoimmunity;

   Sammanfattning : Autoimmunity, such as type 1 diabetes (T1D), arises as a result of tolerance breakdown against host tissues, i.e. the β-cells. Central tolerance is established during thymic T cell development and defects in key events during this process could contribute to the pathogenesis of autoimmune diseases. LÄS MER

7. 15. T Cells and NK Cells in Coronary Artery Disease : Longitudinal and methodological studies in humans

   Författare :Karin Backteman; Jan Ernerudh; Lena Jonasson; Joachim Lundahl; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Coronary artery disease (CAD) is the leading cause of death worldwide and most often due to atherosclerosis. Atherosclerosis is a chronic inflammatory process that involves the arteries, inclouding those that supply blood to the heart muscle. LÄS MER
