摘要: A disulfide trap, comprising an antigen peptide covalently attached to an MHC class I heavy chain molecule by a disulfide bond extending between two cysteines, is disclosed. In some configurations, a disulfide trap, such as a disulfide trap single chain trimer (dtSCT), can comprise a single contiguous polypeptide chain. Upon synthesis in a cell, a disulfide trap oxidizes properly in the ER, and can be recognized by T cells. In some configurations, a peptide moiety of a disulfide trap is not displaced by high-affinity competitor peptides, even if the peptide binds the heavy chain relatively weakly. In various configurations, a disulfide trap can be used for vaccination, to elicit CD8 T cells, and in multivalent MHC/peptide reagents for the enumeration and tracking of T cells. Also disclosed are nucleic acids comprising a sequence encoding a disulfide trap. Such nucleic acids, which can be DNA vectors, can be used as vaccines.
摘要翻译: 公开了包含通过在两个半胱氨酸之间延伸的二硫键共价连接到MHC I类重链分子上的抗原肽的二硫键。 在一些构型中,二硫键陷阱,例如二硫键捕获单链三聚体(dtSCT)可以包含单个连续的多肽链。 在细胞中合成时,二硫键在ER中正确氧化,可被T细胞识别。 在一些构型中,即使肽相对较弱地结合重链,二硫键陷阱的肽部分也不会被高亲和力的竞争者肽置换。 在各种构型中,二硫键可用于疫苗接种,引发CD8 T细胞和多价MHC /肽试剂,用于计数和追踪T细胞。 还公开了包含编码二硫键的序列的核酸。 可以使用这样的可以是DNA载体的核酸作为疫苗。

摘要: The present invention provides crystalline forms of domain III of the West Nile Virus (“WNV”) envelope protein in complex with a Fab fragment of a neutralizing antibody, methods of obtaining such crystals and high-resolution structures and atomic structure coordinates. The crystals of the invention and the atomic structural information are useful for solving crystal and solution structures of related and unrelated proteins, and for screening for, identifying or designing compounds or antibodies that bind to, modulate a biological activity of, or neutralize infection mediated by flaviviral envelope proteins.
