  1. 1. Co-stimulation in gut mucosal immunity. Evidence of a differential regulationof local and systemic responses

    University dissertation from Göteborg

    Author : Eva Gärdby; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosal immunity; PP; cholera toxin; oral immunization; co-stimulation; Th1 Th2;

    Abstract : In recent years we have learned that co-stimulatory factors are required as second signals for optimal T cell stimulation. Most types of immune responses are, therefore, dependent on the co-stimulatory signals that are provided by infection or immunization. READ MORE

  2. 2. Modulation of cytokine production by mononuclear cells in allergic inflammation. The effects of allergen exposure and anti-inflammatory agents

    University dissertation from Göteborg : Göteborgs Universitet

    Author : Katarzyna Wosinska-Becler; Göteborgs universitet.; Gothenburg University.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytokines; seasonal allergy; kinetics; CysLTR1 antagonist; montelukast; rush immunotherapy; monocyte; basophil; eosinophil; NK cell; T cell;

    Abstract : In pollen-sensitized subjects, seasonal allergen exposure results in clinical allergic disease, which in affected tissues displays a morphological picture typical of chronic inflammation. The cellular responses to allergens include the production of inflammatory cytokines that can be examined in peripheral blood cells. READ MORE

  3. 3. Innate and adaptive immune responses in the lungs. Contribution to protection against mycobacterial infections

    University dissertation from Stockholm : The Wenner-Gren Institute, Stockholm University

    Author : Olga Daniela Chuquimia Flores; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Host defense against Mycobacterium tuberculosis (Mtb) is mediated by a combination of innate and adaptive immunity. In this thesis we investigated the role of components of innate system such as TLR2 signalling and alveolar epithelial cells type II (AEC II) in the immune responses against mycobacterial infections.

  4. 4. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

    University dissertation from Umeå : Umeå universitet

    Author : Moorix Mo-Wai Yeung; Umeå universitet.; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestine; ulcerative colitis; lymphoid aggregates; intraepithelial lymphocytes; lamina propria lymphocytes; γδT-cells; cytokines; IL-2; carcinoembryonic antigen; biliary glycoprotein; epithelial cells; glycocalyx;

    Abstract : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. READ MORE

  5. 5. Innate mechanisms in upper airway inflammation with focus on epithelium and neutrophils

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Julia Arebro; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Mucosal inflammation is a key feature in allergic rhinitis (AR) and chronic rhinosinusitis with nasal polyps (CRSwNP). The traditional idea of the epithelium as a simple barrier and neutrophils as a homogenous cell population, already terminally differentiated, has lately been reconsidered. READ MORE
