Background
In V. cholerae, the biogenesis of capsule polysaccharide is poorly understood. The elucidation of capsule structure and biogenesis is critical to understanding the evolution of surface polysaccharide and the internal relationship between the capsule and LPS in this species. V. cholerae serogroup O31 NRT36S, a human pathogen that produces a heat-stable enterotoxin (NAG-ST), is encapsulated. Here, we report the covalent structure and studies of the biogenesis of the capsule in V. cholerae NRT36S. 相似文献73.

The expression of influenza virus hemagglutinin in the pancreatic beta cells of transgenic mice results in autoimmune diabetes 总被引:6,自引:0,他引:6
Insulin-dependent diabetes mellitus results from the autoimmune destruction of the insulin-producing beta cells of the pancreatic islets. The target antigen(s) involved in this immunopathological process has not been identified. Our strategy was to determine whether expression of a novel surface antigen by murine pancreatic beta cells would result in insulin-dependent diabetes mellitus. We have generated lines of transgenic mice (RIP-HA) that express the hemagglutinin of the A/Japan/305/57 strain of influenza virus on their insulin-producing beta cells. Hyperglycemia developed in mice derived from all three founders at a frequency varying from 13% to 27%, and was associated with lymphocytic infiltration of the islets and a humoral response against beta cell antigens, including hemagglutinin. These results suggest that the RIP-HA mice should provide a useful system in which to study the cellular interactions involved in the induction of self-tolerance and autoimmunity. 相似文献

A ligand-based approach to identify potential starting points for a dual MCH-1R antagonist/DPPIV inhibitor medicinal chemistry program was undertaken. Potential ligand pairs were identified by analysis of MCH-1R and DPPIV in vitro data. A highly targeted synthetic effort lead to the discovery of pyridone 11, a dual MCH-1R antagonist/DPPIV inhibitor with selectivity over DPP8 and DPP9. 相似文献
