  2. 16. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

    Author : Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

    Abstract : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. READ MORE

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

    Author : Carina Lundqvist; Marie-Louise Hammarström; Sten Hammarström; Per Brandtzaeg; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 18. Intestinal dendritic cell migration and induction of T cell responses

    Author : Karin Hägerbrand; Adaptivt immunförsvar; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The intestine represents the body’s largest surface exposed to the outer world and is thus a major entry site for pathogens such as bacteria and viruses. The intestinal immune system has the important task of protecting us against infection while maintaining tolerance against the vast amount of commensal microbes populating the intestinal tract and the multitude of foreign antigen present in the diet.

  6. 19. Maturation of humoral immune responses : Studies on the effects of antigen type, apoptosis and age

    Author : Karin Lindroth; Carmen Fernández; Kenneth G.C. Smith; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunology; B cell; humoral immune response; Immunology; Immunologi;

    Abstract : The humoral immune response is dependent on the formation of antibodies. Antibodies are produced by terminally differentiated B cells, plasma cells. Plasma cells are generated either directly from antigen challenged B cells, memory cells or from cells that have undergone the germinal center (GC) reaction. READ MORE

  7. 20. Therapeutic dendritic cell vaccination against human papillomavirus

    Author : Merja Nurkkala Karlsson; Göteborgs universitet; []
    Keywords : human papillomavirus; therapeutic dendritic cell vaccination; cholera toxin; T cells; TLRs and CpG;

    Abstract : Cervical cancer, which is caused by infection with human papillomavirus (HPV), is the second most common cancer among women worldwide, leading to 230000 deaths annually. The two currently available HPV vaccines can only be used prophylactically, so they are of no use to the 291 million women who are already infected and at risk of developing cancer. READ MORE
