  1. 21. EFFECTOR T CELL HOMING TO THE SMALL INTESTINAL MUCOSA

    Författare :Hanna Stenstad; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; Immunology; serology; homing; intestine; GALT; chemokine receptor; lymphocyte; serologi;

    Sammanfattning : The intestinal mucosa, including the intestinal epithelium and underlying lamina propria (LP), contains a large number of effector/memory T cells that are thought to play a central role in the generation and maintenance of mucosal immune responses and in maintaining mucosal integrity. The work in this thesis investigates the mechanisms regulating effector T cell recruitment to the small intestinal mucosa focusing on the role of chemokine receptors in this process. LÄS MER

  3. 22. Chemoattractant receptor signaling and neutrophil acctivation. Involvement of the cytoskeleton

    Författare :Huamei Fu; Göteborgs universitet; []
    Nyckelord :neutrophils; G-protein coupled receptors; signaling; cytoskeleton;

    Sammanfattning : Neutrophil granulocytes play a vital role in the host surveillance system and form the first line of defense against microbial infections. The migration of neutrophils to an infected/inflamed tissue is guided by chemoattractants released either from intruding microbes or from activated/damaged host cells. LÄS MER

  4. 23. Molecular diagnostics of infectious diseases

    Författare :Malin Nygren; KTH; []
    Nyckelord :;

    Sammanfattning : In DNA-based diagnostics, the polymerase chain reaction(PCR) is the most widely used DNA amplification method. Toenable both sensitive and specific detection of agents causinginfectious diseases, the PCR needs to becombined with methodsto prepare the clinical sample containing the genetic materialof the pathogen.

  5. 24. Modulatory effects and interactions of substance P, dopamine and 5-HT in a neuronal network

    Författare :Erik Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Lamprey; spinal cord; neuromodulation; substance P; 5-HT; dopamine;

    Sammanfattning : The spinal neuronal network that generates the locomotor rhythm in lamprey contains excitatory and inhibitory interneurons, reticulospinal inputs from the brainstem, and motor neurons. In this thesis, I have studied how the spinal locomotor network cart be modulated by a tachykinin, dopamine and 5- HT that are co-localized in midline neurons situated below the central canal.

  7. 25. Activation of professional phagocytes with emphasis on the formyl peptide receptor family

    Författare :Jennie Karlsson; Göteborgs universitet; []
    Nyckelord :phagocyte; G-protein coupled receptor; chemoattractant; formyl peptide receptor; reactive oxygen species; calcium;

    Sammanfattning : Phagocytic cells such as neutrophil granulocytes and monocytes are an essential part of our innate immune system and play an important role in the battle against pathogens. G-protein coupled receptors (GPCRs) and more specifically chemoattractant receptors are a vital part in guiding phagocytes towards the site of infection. LÄS MER
