    • Applicants disclose herein novel methods, vectors, and vector compositions for improving the efficiency of adenoviral vectors in the delivery and expression of heterologous nucleic acid encoding a polypeptide(s) (e.g, a protein or antigen) of interest. Adenoviral infection is quite common in the general population, and a large percentage of people have neutralizing antibodies to the more prevalent adenoviral serotypes. Such pre-existing anti-adenoviral immunity can dampen or possibly abrogate the effectiveness of this virus for the delivery and expression of heterologous proteins or antigens. The method taught herein functions to offset pre-existing immunity through the delivery of the protein or antigen by a cocktail of at least two adenoviral serotypes. Utilizing a composition of at least two adenoviral serotypes in this manner has been found to increase the effectiveness of adenoviral administration. Adenoviral vectors of utility in the elicitation of an immune response against Human Immunodeficiency Virus ("HIV") are also disclosed.
    • 申请人在此公开用于提高腺病毒载体在递送和表达编码感兴趣的多肽(例如,蛋白质或抗原)的异源核酸的表达中的效率的新颖方法,载体和载体组合物。 腺病毒感染在普通人群中相当常见,并且大部分人具有针对更普遍的腺病毒血清型的中和抗体。 这种预先存在的抗腺病毒免疫力可抑制或可能消除该病毒对异源蛋白质或抗原递送和表达的有效性。 本文教导的方法用于通过由至少两种腺病毒血清型的混合物递送蛋白质或抗原来抵消预先存在的免疫性。 已经发现以这种方式利用至少两种腺病毒血清型的组合物可以增加腺病毒给药的有效性。 也公开了用于引发针对人类免疫缺陷病毒(“HIV”)的免疫应答的腺病毒载体。
