  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. 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

  5. 3. Candida albicans adaption to host microenvironments drives immune evasion

    Author : José Pedro Lopes; Constantin F. Urban; Alistair Brown; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fungi; candida albicans; neutrophils; mast cells; immune evasion; mycoses; infectious diseases; immunologi; Immunology; Infectious Diseases; infektionssjukdomar; Molecular Immunology; molekylär immunologi;

    Abstract : Immunosuppressed patients are frequently afflicted with severe mycoses caused by opportunistic fungal pathogens. Besides being a commensal colonizing predominantly skin and mucosal surfaces, Candida albicans is the most common human fungal pathogen. READ MORE

  6. 4. Aspects of Staphylococcus aureus in Chronic Rhinosinusitis

    Author : Ulrica Thunberg; Bo Söderquist; Svante Hugosson; Hans Fredlund; Johan Hellgren; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic rhinosinusitis; Staphylococcus aureus; enterotoxins; immune response; SNP; clinical features;

    Abstract : Chronic rhinosinusitis (CRS) affects about 10% of the European population, and is considered a great scourge. Its cause is not clear. Findings of Staphylococcus aureus in the maxillary sinus are common in CRS patients, but are usually regarded as insignificant due to the bacterium’s attribute as a commensal elsewhere. S. READ MORE

  7. 5. 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
