11. Role of the Yersinia protein YopK in microbe-host interactions
Sammanfattning : There are three human pathogenic species of the genus Yersiniae: Yersinia pestis, Yersinia enterocolitica, and Yersinia pseudotuberculosis. To cause disease, these strains inhibit several key innate defense mechanisms, including phagocytosis, the critical process for bacterial clearance. LÄS MER
12. Bacterial epithelial interaction in intestinal inflammation
Sammanfattning : The intestine is constantly exposed to bacteria, invading viruses and ingested food. The intestinal barrier serves as a gate preventing passage of harmful components, and at the same time maintaining absorption of nutrients and water. LÄS MER
13. Co-stimulation in gut mucosal immunity. Evidence of a differential regulationof local and systemic responses
Sammanfattning : In recent years we have learned that co-stimulatory factors are required as second signals for optimal T cell stimulation. Most types of immune responses are, therefore, dependent on the co-stimulatory signals that are provided by infection or immunization. LÄS MER
14. Intestinal IgA synthesis: Localization and requirements for IgA class switch recombination
Sammanfattning : Production of IgA at mucosal surfaces is one of the most striking features of the mucosal immune system. Despite that IgA was first discovered in the 1950’s and secretory IgA described in gut secretions and breast milk in the mid 1960’s we still have limited information about the sites and exact requirements for IgA class switch recombination.
