  1. 21. Immune Regulation During Malaria Infection

    Författare :Helena Helmby; Edvard Pearce; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Sammanfattning : Malaria is the largest parasitic disease in the world and is caused by the protozoon Plasmodium. The most severe form in humans is caused by Plasmodium falciparum. Immunity to malaria involves both cell-mediated and humoral responses and develops slowly over a period of ten to fifteen years, requiring repeated infections. LÄS MER

  3. 22. Heavy Metal Superantigen : Genetic Regulation of Lymphocyte Activation by HgC12

    Författare :Yun Jiang; Peter Mathieson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Sammanfattning : Injections of subtoxic doses of HgCl2 (mercuric chloride) cause a systemic autoimmune disease in genetically predisposed rats and mice. My work was designed to elucidate how HgCl2 induces lymphocyte activation and how the response to HgCl2 is regulated in susceptible and resistant strains. LÄS MER

  4. 23. Cytokine studies in the generation and treatment of IgE-mediated allergy

    Författare :Ankie Söderlund; Huub Savelkoul; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cytokines; Hypersensitivity; Allergy; Allergi; immunologi; Immunology;

    Sammanfattning : So called Th2 cytokines, such as IL-4 and IL-13 are responsible for the formation of IgE antibodies, the effector antibody in atopic allergy. Cytokines of Th1 type, for example IFN-g, inhibit these responses. This thesis describes work aimed at elucidating the cytokine production underlying IgE-mediated allergy. LÄS MER

  5. 24. Glutamate and GABA signalling components in the human brain and in immune cells

    Författare :Amol K. Bhandage; Bryndis Birnir; Gerard P. Ahern; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neuroscience; Neurovetenskap; Immunologi; Immunology;

    Sammanfattning : Glutamate and γ-aminobutyric acid (GABA) are the principal excitatory and inhibitory neurotransmitters in the central nervous system (CNS). They both can activate their ionotropic and metabotropic receptors. LÄS MER

  7. 25. Early childhood thymectomy - impact on immune function

    Författare :Judith Gudmundsdottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Immunologi; Thymus; Pediatric cardiac surgery; Congenital heart defect;

    Sammanfattning : Introduction: The thymus is the site of T cell maturation. Children born with a congenital heart defect often endure surgery early in life, and during surgery their thymus is routinely removed, as it blocks the surgeons access to the heart. LÄS MER
