摘要:
The present invention relates to a conjugate comprising an oligo- or polysaccharide selected from the group consisting of: (X) x -{BCDA} n -(Y) y (X) x -{CDAB} n -(Y) y (X) x -{DABC} n -(Y) y (X) x -{ABCD}n-(Y) y wherein A, B, C, D, X and Y, x, y and n are as defined in claim 1, said oligo- or polysaccharide being bound to a carrier.
摘要:
The present invention relates to compounds derived from sugars which reproduce the epitopes of Shigella flexneri serotypes 3a and X and to the use thereof for the preparation of vaccine compositions. More specifically, the subject matter of the present invention relates to novel glycoconjugated compounds comprising oligosaccharides or polysaccharides described hereinafter, to the method for synthesizing these oligosaccharides or polysaccharides and glycoconjugates, to derivatives of these oligosaccharides or polysaccharides, to compositions containing same, and also to the use of the glycoconjugates for vaccination purposes. Finally, the present invention relates to methods for diagnosing a Shigella flexneri infection using one or more oligosaccharides or polysaccharides or conjugates thereof.

摘要:
The ospF gene of Shigella flexneri encodes a phosphatase, which is a member of a new class of phosphatases. The OspF phosphatase inhibits the activity of several proteins either by direct protein modification or transcription downregulation. These proteins include MAP kinase, IL-8, CCL20, IL-12, AP1, CREB, RPA p32, and BCL2 related proteins. Methods for treating diseases using OspF phosphatase, methods for identifying agents that modulate OspF phosphatase's activity, methods for identifying agents that mimic OspF phosphatase's activity, and immunogenic compositions comprising OspF phosphatase are provided. A strain of Shigella flexneri containing an inactivated ospF gene is also provided.
