  1. 1. Intracellular regulation of TLR signaling Basic mechanisms and importance in intestinal inflammation

    Författare :Martin Berglund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TLR IL-1R signalling; Gαi2- - mice; IRAK; peritoneal macrophages; cross-tolerance; dextran sulfate sodium; IBD;

    Sammanfattning : Toll-like receptors (TLRs) recognize conserved structures on/in microorganisms. The intracellular signalling pathways of TLRs are shared with IL-1R and IL-18R and their activation leads to transcription of proinflammatory cytokines and type-I interferons. LÄS MER

  3. 2. Signal transduction in macrophages. Intracellular pathways activated by microbial constituents

    Författare :Sandra Olsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; TNF; TLR; dectin-1; lipid rafts; Src; Btk; Macrophages; arachidonate;

    Sammanfattning : Macrophages play an essential role in the defense against infection by phagocytosis and by production of inflammatory mediators. Such mediators are TNF? and eicosanoids. Many microbial agents elicit arachidonate release in macrophages that lead to the formation of eicosanoids. LÄS MER

  4. 3. Dysregulated mucosal immune responses in microscopic colitis patients

    Författare :Sezin Günaltay; Elisabeth Hultgren-Hörnquist; Olof Hultgren; Nils Nyhlin; Allan Mowat; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microscopic colitis; collagenous colitis; lymphocytic colitis; TLR; chemokine; chemokine receptor; IL-37; TCR; Immunologi; Immunology; Biomedicin; Biomedicine;

    Sammanfattning : Microscopic colitis (MC), comprising collagenous colitis (CC) and lymphocytic colitis (LC) is a common cause of chronic watery diarrhea. The diagnosis relies on typical histopathological changes observed upon microscopic examination. LÄS MER

  5. 4. Development of novel immunization approaches to generate immunity in the female genital tract with special reference to genital herpes

    Författare :Sara Tengvall; Göteborgs universitet; []
    Nyckelord :female genital tract immunity; genital herpes; mucosal adjuvant; TLR; MyD88; CpG ODN;

    Sammanfattning : Development of mucosal vaccines for inducing immunity in the female reproductive tract would have profound implications for the prevention of sexually transmitted diseases. Despite numerous efforts, no such vaccines are currently available for human use. LÄS MER

  7. 5. Effects of Complement Opsonization of HIV on Dendritic Cells : and Implications for the Immune Response

    Författare :Rada Ellegård; Marie Larsson; Jorma Hinkula; Johan D Söderholm; William Paxton; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HIV; dendritic cells; complement; innate immune response; TLR signaling; T cell activation; NK cells; inflammation; antiviral response; immune evasion;

    Sammanfattning : Dendritic cells are key players during HIV pathogenesis, and shape both the immediate immune response at the site of infection as well as directing the adaptive immune response against the virus. HIV has developed a plethora of immune evasion mechanisms that hijack dendritic cell functions, suppressing their ability to mount an accurate immune response and exploiting them for efficient viral transfer to target T cells.
