  2. 1. Human dendritic cells : a study of early events during pathogen recognition and antigen endocytosis

    Author : Peter Hellman; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dendritic cells; zeolites;

    Abstract : The mononuclear phagocyte cell system includes monocytes, macrophages anddendritic cells which are important cells in order to recognize, ingest, destroyand also present part of a pathogen to T-lymphocytes in order to activate theadaptive immune system. Dendritic cells (DCs) stand out in their ability tostimulate T-lymphocytes and are also believed to be important to keeptolerance for “self-antigens”. READ MORE

  4. 2. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization

    Author : Lucia Mincheva-Nilsson; Sten Hammarström; Rolf Kiessling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologically privileged site; TCR γδ cells; CD56 cells; large granular lymphocytes; immunosuppression; cytokine; interleukin; lymphoid cell cluster; intraepithelial lymphocytes; glandular epithelium; immuno electron microscopy; pregnancy; decidua; lactoferrin; lactoferrin receptor; colostrum;

    Abstract : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. READ MORE

  5. 3. Human mononuclear phagocytes : Production of reactive oxygen species generated by the NADPH oxidase

    Author : Agneta Johansson; Roger Sundler; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Human professional phagocytes constitute the first line of defence against invading microorganisms. With a membrane-bound enzyme system, the NADPH oxidase, these cells generate bactericidal metabolites. Activation of NADPH oxidase results in a generation of reactive oxygen species, e.g. READ MORE

  6. 4. The ontogeny and function of intestinal dendritic cells

    Author : Emma Persson; Slemhinnans immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenteric lymph nodes; Intestine; Dendritic cells; Gut-homing; Th17 cells; Oral tolerance; Immunity;

    Abstract : 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.

  7. 5. Lactobacilli- and Staphylococcus aureus mediated modulation of immune responses in vitro

    Author : Yeneneh Haileselassie; Eva Sverremark-Ekström; Huub Savelkoul; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lactobacilli; staphylococcus aureus; dendritic cells; retinoic acid; epithelial cells; T cells; immunologi; Immunology;

    Abstract : The human gut harbors a vast number of microbes. These microbes are not passive bystanders. They are important in modulating the immune system. We have previously shown that early colonization with lactobacilli and Staphylococcus (S. READ MORE
