6. Vesicle-independent extracellular release and bioactivity of peptidoglycan-associated lipoprotein from Aggregatibacter actinomycetemcomitans
Abstract : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a Gram-negative coccobacillus of the Pasteurellaceae family. It is implicated in periodontitis, a common low-grade bacterial infection, but it can also cause non-oral infections. The main aim of this project was to identify and characterize in A. READ MORE

7. Receptor Interactions Between Pathogenic Bacteria and Host Cells
Abstract : This thesis focuses on host and pathogen specific interactions during invasive disease. We have investigated the role and impact of different virulence factors of Neisseria gonorrhoeae, N. meningitidis and Streptococcus pyogenes on host epithelial cells and in vivo. N. READ MORE

8. Interplay between bacteria and host epithelial cells
Abstract : Bacterial pathogens have developed multiple ways of manipulating host cell functions to exploit the host environment. We found that interactions with epithelial cells increase the resistance of the human pathogen Neisseria meningitidis to the antimicrobial peptide LL-37. READ MORE

9. Outer membrane vesicle-mediated export of virulence factors from Gram-negative bacteria
Abstract : The Gram-negative, motile bacterium Campylobacter jejuni is a causative agent of food-borne gastroenteritis. Cytolethal distending toxin (CDT) is one of the important virulence factors for C. jejuni pathogenesis. It was not previously known how CDT is released from C. READ MORE

10. Influence of host and bacterial factors during Neisseria meningitidis colonization
Abstract : The human-restricted pathogen Neisseria meningitidis is a major cause of bacterial meningitis and sepsis worldwide. Colonization of the mucosal layer in the upper respiratory tract is essential to establish an asymptomatic carrier state and invasive disease. N. READ MORE
