  1. 31. A tripartite of immune-, epithelial-, and nervous-systems in the homeostatic regulation of the gut

    Författare :Song Hui Chng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Various cell types in the intestinal mucosa are constantly exposed to complex signals emanating from the lumen, including the microbiota and its metabolites. How these bilateral interactions in turn influences intestinal homeostasis is an important question in order to understand microbiota-host interactions. LÄS MER

  3. 32. Chemokine Receptor CCR9: Studies on the Generation and Localization of Gut Tropic Lymphocytes

    Författare :Marcus Svensson Frej; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small intestine; transplantation; serologi; CCR9; CCL25; chemokines; lymphocyte homing; Immunology; serology; Immunologi;

    Sammanfattning : Lymphocytes are important mediators of adaptive immune responses. Naive T lymphocytes circulate in the blood and lymph between different secondary lymphoid organs in search for their specific antigen. LÄS MER

  4. 33. Studies of the pathogenesis of Enterohemorrhagic Escherichia coli infections: pathogen virulence factors and host response

    Författare :Carla Calderon Toledo; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; host-pathogen; MyD88; TLRs; LEE; Shiga toxin; HUS; EHEC; EPEC; immune response; virulence factors;

    Sammanfattning : Enterohemorrhagic Escherichia coli (EHEC) is a highly virulent pathogen that can cause diarrhea and a life-threatening disease known as hemolytic uremic syndrome. EHEC possess an array of virulence factors that can exert severe consequences in the host. Shiga toxin constitutes a key virulence factor. LÄS MER

  5. 34. Studies of Mucosal Immune Regulation in Celiac Disease and Type 1 Diabetes

    Författare :Anne Lahdenperä; Johnny Ludvigsson; Outi Vaarala; Rosaura Casas; Eva Sverremark-Ekström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Background: Celiac disease (CD) and type 1 diabetes (T1D) are two chronic autoimmune diseases with increasing incidence worldwide. A combination of genetic, environmental and immunological factors is considered to be involved in development of the diseases, even though the exact disease mechanisms still are unknown. LÄS MER

  7. 35. Defensins and cytokines in inflammatory bowel disease

    Författare :Arman Rahman; Mats Andersson; Umeå universitet; []
    Nyckelord :immunologi; Immunology;

    Sammanfattning : Ulcerative colitis (UC) and Crohn’s disease (CD) constitute the two major inflammatory bowel diseases in man. Both are serious chronic illnesses of the intestine with severe debilitating effects. The etiology of the diseases is unknown, but involvement of both adaptive and innate immune reactions seems to be major factors in the pathogenesis. LÄS MER
