Bacterial components in experimental intestinal inflammation prevention and therapy
 Kverka, Miloslav ; Tlaskalová - Hogenová, Helena (advisor) ; Šedivá, Anna (referee) ; Stříž, Ilja (referee)
Although strong protective immune response is essential for preventing invasion by pathogens, equivalent responses against antigens originating from commensal bacteria can lead to chronic inflammatory diseases, such as inflammatory bowel disease (IBD). Manipulating the mucosal immune responses with microbial antigens might be an excellent tool to IBD therapy or prevention. Our aim was to gain some insight into the regulation of the intestinal inflammation and to isolate bacterial immunomodulatory components that could be used in intestinal inflammation therapy and prevention. One particular mechanism of how healthy colon tissue regulates the inflammation during acute experimental colitis is through modulation of bioavailability of glucocorticoids (GCs) in gut mucosa. Here, we show that intestinal inflammation changes the local GC metabolism, which ultimately leads to decrease in inflammatory readiness of cells in the gut mucosa and in mesenteric lymph nodes. This pre-receptor regulation of GC function could represent an important homeostatic function of the gut mucosa. The actual triggers of intestinal inflammation in IBD seem to be either microbial dysbiosis or microbes with special "pathogenic" abilities, which both could be rectified by feeding with probiotics. Here, we report that oral feeding with live...
