Description:
A titer for homologous viral neutralization activity (greater than 1:19,683) was observed after a 3.5-year immunization period with an octameric, branching peptide representing the principal neutralizing determinant (PND) of the human immunodeficiency virus-1IIIB envelope protein. Booster immunizations elicited persistent and potent antibodies in guinea pigs, exceeding responses produced by a conventional bovine serum albumin conjugate by 100-fold. Peptide length, central presentation of a conserved sequence, and inclusion of an upstream sequence contributed to immunogenicity. Titers (greater than 1:1,000) of heterotypic neutralizing antibodies also developed. Octameric PND peptides are a promising approach for an acquired immunodeficiency syndrome (AIDS) vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, C Y -- Looney, D J -- Li, M L -- Walfield, A M -- Ye, J -- Hosein, B -- Tam, J P -- Wong-Staal, F -- IU01-AI-30238/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Oct 11;254(5029):285-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉United Biomedical, Inc., Lake Success, NY 11042.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1925584" target="_blank"〉PubMed〈/a〉
