- Humanized mice and mouse models have been developed to further understanding of the host-pathogen interaction in the human intestine.
- Focus on the virulence mechanisms of human enteropathogens and the role of bacteria in the pathogenesis of Crohn's disease and virulence mechanisms of human-specific gut pathogens such as E. coli O157:H7, EPEC and Salmonella.
- Murine mastitis models have been developed for a second major study focus to promote the understanding of fundamental processes in the mammary gland, including the virulence mechanisms of E. coli in the mammary gland, as well as inflammation and innate immune response.
- A third focus is based on urinary tract infection (UTI) mouse models to study the pathogenesis of UPEC in cystitis
The lab has developed the capabilities for producing humanized mice and superior mouse models. All research is simultaneously conducted in vitro as well as in vivo. Advanced imaging techniques such as confocal microscopy and whole-body imaging, support the research.
The purpose of the research carried out in this lab is (1) to further basic understanding of the mechanisms involved in diseases of the intestine, including IBD and Crohn's disease, and (2) to discover more about the fundamental function of the mammary gland, leading to better understanding of mastitis and other disorders.
Much of the work in this lab is carried out in close collaboration withProfessor Ilan Rosenshine.
