  1. 1. The ontogeny and function of intestinal dendritic cells

    Detta är en avhandling från Mucosal Immunology, EMV, Lund University

    Författare :Emma Persson; Lunds universitet.; Lund University.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenteric lymph nodes; Intestine; Dendritic cells; Gut-homing; Th17 cells; Oral tolerance; Immunity;

    Sammanfattning : The intestinal mucosa presents a huge surface area to the external environment and the intestinal immune system is continually exposed to a wide array of foreign antigens derived from resident intestinal microbiota as well as dietary constituents, including food proteins. In order to maintain intestinal homeostasis, the intestinal immune system relies on the ability to generate tolerogenic responses to innocuous antigen while maintaining the ability to develop effective immune responses to intesinal pathogens.

  2. 2. Causal inference and case-control studies with applications related to childhood diabetes

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Emma Persson; Umeå universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; covariate selection; design-weighted estimation; marginal effect; matching; register study; treatment effect; type 1 diabetes mellitus; Statistics; statistik;

    Sammanfattning : This thesis contributes to the research area of causal inference, where estimation of the effect of a treatment on an outcome of interest is the main objective. Some aspects of the estimation of average causal effects in observational studies in general, and case-control studies in particular, are explored. LÄS MER

  3. 3. The neuropeptide VIP and the IL-6 family of cytokines in bone effects on bone resorption, cytokine expression and receptor signalling in osteoblasts and bone marrow stromal cells

    Detta är en avhandling från Umeå : Odontologi

    Författare :Emma Persson; Umeå universitet.; [2005]
