1. Molecular and morphological studies on non-healing venous leg ulcers
Abstract : Chronic skin ulcers are a major health problem and an increasing burden on health care providers. These ulcers have various underlying causes, such as venous or arterial insufficiency, diabetes, or vasculitis. Non-healing venous leg ulcers represent a condition characterized by excessive inflammation and presence of bacteria. READ MORE

2. Defence capabilities of human intestinal epithelial cells
Abstract : The epithelial cells lining the intestinal mucosa separate the underlying tissue from components of the intestinal lumen. Innate immunity mediated by intestinal epithelial cells (IECs) provides rapid protective functions against microorganisms. Innate immunity also participates in orchestrating adaptive immunity.

3. Human intestinal epithelial cells in innate immunity : interactions with normal microbiota and pathogenic bacteria
Abstract : Rod-shaped bacteria were previously shown to be associated with the small intestinal epithelium of children with celiac disease (CD). Using culture-dependent and independent methods, we characterized the microbiota of small intestine in children with CD and controls. The normal microbiota constitutes an unique organ-specific biofilm. READ MORE

4. Interactions between Streptococcus pyogenes and the human immune defence
Abstract : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

5. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms
Abstract : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. READ MORE
