1. Identification of new virulence factors in Francisella tularensis
Sammanfattning : Francisella tularensis, the causative agent of tularemia, is a highly virulent bacterium with an infection dose of less than ten bacteria. The ability of a pathogen to cause infection relies on different virulence mechanisms, but in Francisella tularensis relatively few virulence factors are known. Two F. LÄS MER
2. Analysis of the molecular interplay between Streptococcus pyogenes and its human host
Sammanfattning : The common human pathogen Streptococcus pyogenes is the causative agent of numerous mild and severe clinical conditions. It expresses a number of secreted or cell wall-anchored proteins that modulate the human immune system and facilitate colonization and spread of the pathogen in the human host. During S. LÄS MER
3. Role of YopE and LcrH in effector translocation, HeLa cell cytotoxicity and virulence
Sammanfattning : In order to establish an extra-cellular infection the gram-negative bacteria Yersinia pseudotuberculosis uses a type III secretion system (T3SS) to translocate a set of anti-host effectors into eukaryotic cells. The toxins disrupt signalling pathways important for phagocytosis, cytokine production and cell survival. LÄS MER
4. Disarming bacteria : a structure-based approach to design an anti-virulence drug against Listeria monocytogenes
Sammanfattning : Antibiotic resistances are one of the biggest threats to global health and if we don’t change our behavior and way of using antibiotics we will end up in a ‘post-antibiotic era’, in which common infections and minor injuries can once kill again and up to 10 million deaths per year may occur by 2050. Therefore, there is a high need for new anti-bacterial drugs, especially of alternatives to existing antibiotics with already described resistances. LÄS MER
5. Controlling virulence in Yersinia pseudotuberculosis through accumulation of phosphorylated CpxR
Sammanfattning : Like many Gram-negative bacteria, the food-borne pathogen Yersinia pseudotuberculosis harbours different regulatory mechanisms to maintain an intact bacterial envelope especially during exposure to extracytoplasmic stress (ECS). The CpxA-CpxR two component regulatory system is one such ECS-responsive regulatory mechanism. LÄS MER
