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

2. Dietary habits, commensal microbiome, and nasopharyngeal carcinoma
Sammanfattning : 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. LÄS MER
3. Innate and acquired immunity to commensal bacteria
Sammanfattning : 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. LÄS MER
4. Sulphonamide Resistance in Neisseria meningitidis and Commensal Neisseria Species
Sammanfattning : 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). LÄS MER
5. Commensal microbes, immune reactivity and childhood inflammatory bowel disease
Sammanfattning : 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. LÄS MER
