  1. 21. The quality control of MHC class I antigen presentation

    Författare :Kajsa M Paulsson; Antigen presentation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperone; assembly; COPI; antigenic peptide; TAP; MHC; tapasin; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : Major histocompatibility complex (MHC) class I molecules present antigenic peptides to CD8+ T cells. The peptides are generated by proteasomes in the cytosol, then translocated across the membrane of the endoplasmic reticulum (ER) by the transporter associated with antigen processing (TAP). LÄS MER

  3. 22. Investigations of Hematopoietic Stem Cells and Their Age-Associated Alterations

    Författare :Alexandra Rundberg Nilsson; Avdelningen för molekylär hematologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cells; Aging; Serial transplantation; Self-renewal; Flow cytometry; Gene expression;

    Sammanfattning : The hematopoietic stem cell (HSC) has and continues to be extensively investigated, and represents by far the most studied somatic stem cell. Development of various experimental technologies, including fluorescence activated cell sorting (FACS), have been crucial for research advancements within the hematopoietic field. LÄS MER

  4. 23. Thymic Stroma and T Cell Development. Impacts of Retinoic Acid Signaling

    Författare :Kerstin Wendland; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thymus; Thymic epithelial cells; Retinoic acid; T cell development; Stromal Cells;

    Sammanfattning : The development of functionally competent, self-tolerant T cells in the thymus is an essential prerequisite for the formation of adaptive immune responses against foreign pathogens. Thymic epithelial cells (TECs) form specialized stromal microenvironments in the cortex (cTEC) and medulla (mTEC) of the thymus that support all stages of T cell development, from the entry of thymocyte progenitors to the exit of mature naive T cells.

  5. 24. Regulation of T cell effector functions in the intestinal mucosa

    Författare :Petra Holmkvist; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cells; memory; intestine; cytokines; differentiation; IL-18; inflammation; antigen presentation;

    Sammanfattning : T lymphocytes are a critical cellular component of the adaptive immune response. They are generated in the thymus from bone marrow derived progenitors, where they undergo commitment to the T cell lineage and differentiate and mature into naïve CD4+ and CD8+ T cells. LÄS MER

  7. 25. T cell Tolerance - Cellular and molecular features of immune regulation

    Författare :Susanna Grundström; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; JAK STAT.; NFkB; suppression; IL-2; superantigen; T cells; tolerance;

    Sammanfattning : The immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. LÄS MER
