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.
摘要:
A conjugate molecule comprising an oligo- or polysaccharide covalently bound to a carrier and its use as potential vaccine against infection by S. Flexneri.

A conjugate molecule comprising an oligo- or polysaccharide covalently bound to a carrier and its use as potential vaccine against infection by S. Flexneri.
摘要:
A purified immunogenic polypeptide comprises an epitope unit recognized by a protective monoclonal antibody having a high affinity and a high specificity for a surface polysaccharide of a pathogenic microorganism of bacterial, viral, or fungal origin. The polypeptide is capable of inducing an immune response in vivo against the pathogenic microorganism. The immune response confers protection in mice against challenge with the virulent microorganisms.
