    • Virus-specific CD4 + T cell help and CD8 + cytotoxic T cell responses are critical for the maintenance of effective immunity in chronic viral infections. The importance of the CD4 + T cells has been documented in HIV infection. A T1-specific CD4 + T cell line from a healthy volunteer immunized with a canarypox vector expressing gpl20 has been developed. The cell line was restricted to DR13, which is common in the U.S. in both Caucasians and African-Americans and is one of the major haplotypes in Africans. Amino acid substitutions in the T1 epitope were made to induce a stronger epitope-specific CD4 + T cell response than the original epitope resulting in an improved CD4 epitope. A polypeptide comprising the enhanced CD4 epitope can be used as a component in compositions either alone or in combination with other adjuvants and other immunogenic compositions to induce a more effective immune response to HIV infection.
    • 病毒特异性CD4 + T细胞帮助和CD8 +细胞毒性T细胞应答对于维持慢性病毒感染中的有效免疫是至关重要的。 在HIV感染中已经记录了CD4 + T细胞的重要性。 已经开发了用表达gp120的金丝细胞病毒载体免疫的健康志愿者的T1特异性CD4 + T细胞系。 细胞系限于DR13,这是美国在高加索人和非洲裔美国人中常见的,是非洲人的主要单倍型之一。 使得T1表位中的氨基酸取代引起比原始表位更强的表位特异性CD4 + T细胞应答,导致改善的CD4表位。 包含增强的CD4表位的多肽可以单独使用或与其它佐剂和其它免疫原性组合物组合用作组合物,以诱导对HIV感染的更有效的免疫应答。
