  2. 1. Regulation of innate and acquired immunity in infants by commensal bacteria

    Author : Helen Karlsson; Göteborgs universitet; []
    Keywords : intestinal microflora; commensal; antigen-presenting cells; dendritic cells; CD25 regulatory T cells; allergy; infants; Staphylococcus aureus;

    Abstract : The incidence of atopic diseases in children is steadily increasing in the industrialised world along with an improved hygienic lifestyle. The gastrointestinal flora may be of specific importance for the proper maturation of the immune system and for the induction of tolerance, in which CD25+ regulatory T cells (Tregs) play a crucial role.

  4. 2. Dietary habits, commensal microbiome, and nasopharyngeal carcinoma

    Author : Tingting Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Nasopharyngeal carcinoma (NPC) is a malignant disease characterized by unique geographic distribution endemic to southern China, Southeast Asia, and the Middle East/North Africa. It has been widely accepted that the interaction of Epstein-Barr Virus infection, environmental and lifestyle factors, and genetic susceptibility, contributes to NPC carcinogenesis. READ MORE

  5. 3. Innate and acquired immunity to commensal bacteria

    Author : Christina Hessle; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The innate immune system recognises molecular patterns shared by large groups of micro-organisms. Monocytes and macrophages respond to microbes by production of substances which act in concert to promote effective clearance of bacteria. READ MORE

  6. 4. Sulphonamide Resistance in Neisseria meningitidis and Commensal Neisseria Species

    Author : Yvonne Qvarnström; Göte Swedberg; Dan Andersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; sulphonamide resistance; Neisseria; natural transformation; adaptive evolution; substrate channelling; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar;

    Abstract : Extensive use of the sulphonamide drugs against the bacterium Neisseria meningitidis has resulted in drug resistance development. Sulphonamide resistance in N. meningitidis is caused by alterations in the chromosomal folP gene, coding for DHPS (dihydropteroate synthase). READ MORE

  7. 5. Commensal microbes, immune reactivity and childhood inflammatory bowel disease

    Author : Cecilia Barkman; Göteborgs universitet; []
    Keywords : Inflammatory bowel disease; IBD; Pediatric; Childhood; Microbiota; T cells; B cells; cytokine; IL-12; monocytes; phagocytosis; intracellular signaling pathway; Crohn s disease; ulcerative colitis; children; flora;

    Abstract : Inflammatory bowel disease (IBD) is characterized by chronic and relapsing intestinal inflammation of unknown etiology, but immune activation by the commensal microbiota probably plays a major role. The two major categories of IBD are ulcerative colitis and Crohn’s disease. READ MORE
