    • Methods of delivering a cargo moiety to a cell is provided according to embodiments of the invention which includes contacting a cell expressing sialoadhesin with a conjugate including a sialoadhesin binding moiety and a cargo moiety. The sialoadhesin binding moiety binds to the sialoadhesin expressed by the cell and is internalized along with the cargo, delivering the cargo moiety to the cell. Particular methods provided by the invention include induction or enhancement of sialoadhesin expression in a cell which naturally produces little or no sialoadhesin. Induction or enhancement of sialoadhesin expression includes transfection of a sialoadhesin expression construct and/or administration of an agent effective to induce or enhance sialoadhesin expression. Methods and compositions for stimulating an immune response in a subject are detailed. Particular methods and compositions for stimulating an immune response to a virus are provided by the invention.
    • 根据本发明的实施方案提供将货物部分递送到细胞的方法,其包括使表达唾液酸粘附素的细胞与包含唾液酸粘附素结合部分和货物部分的缀合物接触。 唾液酸粘附素结合部分结合由细胞表达的唾液酸粘附素,并与货物一起内化,将货物部分输送至细胞。 本发明提供的具体方法包括在天然产生很少或不含唾液酸粘蛋白的细胞中诱导或增强唾液酸粘附素表达。 唾液酸粘附素表达的诱导或增强包括转染唾液酸粘附素表达构建体和/或施用有效诱导或增强唾液酸粘附素表达的试剂。 详细说明刺激受试者免疫应答的方法和组合物。 用于刺激对病毒的免疫应答的特定方法和组合物由本发明提供。
