Upregulation of Toll-like receptor 2 and nuclear factor-kappa B expression in experimental colonic schistosomiasis.

Role of different mediators was described in the development of the granulomatous response and fibrosis observed in intestinal schistosomiasis. However, both Toll-like receptor 2 (TLR2) and nuclear factor kappa B (NF-κB) have not yet been investigated in intestinal schistosomiasis. This study aimed to characterize the role of TLR2 and NF-κB in the pathogenesis of intestinal schistosomiasis.

FoxP3+ T regulatory cells and immunomodulation after Schistosoma mansoni egg antigen immunization in experimental model of inflammatory bowel disease.

To assess the effect of Schistosoma mansoni egg antigen immunization on the immunomodulation in dextran sodium sulfate (DSS) induced colitis as an experimental model of IBD in comparison to non immunization and healthy control. The study was performed on 180 mice; 25 healthy control, 15 to identify the inflammatory peak of DSS, 25 received DSS for 7 days; 90 infected with S. mansoni cercariae to collect eggs for antigen preparation, and 25 immunized with the prepared antigen then received DSS course.
