  1. 1. The immortalization process of T cells : with focus on the regulation of telomere length and telomerase activity

    Författare :Sofie Degerman; Göran Roos; John Sedivy; Umeå universitet; []
    Nyckelord :immortalization; senescence; T cells; Nijmegen breakage syndrome; telomere; telomerase; hTERT; generic aberrations; methylation; MEDICINE; MEDICIN; Pathology; patologi;

    Sammanfattning : Cellular immortalization is a major hallmark of cancer and is a multi-step process that requires numerous cell-type specific changes, including inactivation of control mechanisms and stabilization of telomere length. The telomeres at the chromosome ends are essential for genomic stability, and limit the growth potential of most cells. LÄS MER

  3. 2. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa

    Författare :Carina Lundqvist; Marie-Louise Hammarström; Sten Hammarström; Per Brandtzaeg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intraepithelial lymphocytes; alimentary tract; intestinal epithelium; gut luminal antigens; gingiva; γδ T cells; immunoelectron microscopy; cytokine mRNA; RT-PCR; extrathymic T cell maturation; RAG-1; periodontitis; mucosal immune system; CD4-CD8- αβ T cells; CD8 γδ T cells;

    Sammanfattning : Human intraepithelial lymphocytes (IEL) constitute a unique cell population situated in the first line of defense of the alimentary tract. Here they are continuously exposed to a massive antigenic load of high complexity. However, different conditions prevail along the alimentary tract. LÄS MER

  4. 3. Regulatory T cells in human pregnancy

    Författare :Jenny Mjösberg; Jan Ernerudh; Göran Berg; Anna Rudin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : During pregnancy, fetal tolerance has to be achieved without compromising the immune integrity of the mother. CD4+CD25highFoxp3+ regulatory cells (Tregs) have received vast attention as key players in immune regulation. However, the identification of human Tregs is complicated by their similarity to activated nonsuppressive T cells. LÄS MER

  5. 4. Cancer Immunotherapy : Evolving Oncolytic viruses and CAR T-cells

    Författare :Mohanraj Ramachandran; Magnus Essand; Di Yu; Justyna Leja-Jarblad; Richard Vile; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncolytic virus; Adenovirus; Semliki Forest virus; Cancer immunology; Chimeric antigen receptor T-cells; Immunologi; Immunology; Oncology; Onkologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : In the last decade cancer immunotherapy has taken huge strides forward from bench to bedside and being approved as drugs. Cancer immunotherapy harnesses the power of patient’s own immune system to fight cancer. LÄS MER

  7. 5. T cells in colon cancer; migration and effector functions

    Författare :Louis Szeponik; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Treg; CRC; TIL; nSMase2; Transendothelial migration; Unconventional T cells;

    Sammanfattning : Immune cells are recognised as one of the main players in the tumor microenvironment and targeted by many new cancer therapies. Regulatory T cells (Treg) can suppress tumor infiltrating lymphocytes which are associated with a better patient outcome. LÄS MER
