Topical agents, such as microbicides, that can protect against human immunodeficiency virus (HIV) transmission are urgently needed. Using a chimeric simian/human immunodeficiency virus (SHIV SF162), which is tropic for the chemokine receptor CCR5, we report that topical application of high doses of PSC-RANTES, an amino terminus-modified analog of the chemokine RANTES, provided potent protection against vaginal challenge in rhesus macaques. These experimental findings have potentially important implications for understanding vaginal transmission of HIV and the design of strategies for its prevention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lederman, Michael M -- Veazey, Ronald S -- Offord, Robin -- Mosier, Donald E -- Dufour, Jason -- Mefford, Megan -- Piatak, Michael Jr -- Lifson, Jeffrey D -- Salkowitz, Janelle R -- Rodriguez, Benigno -- Blauvelt, Andrew -- Hartley, Oliver -- AI 36219/AI/NIAID NIH HHS/ -- AI 51649/AI/NIAID NIH HHS/ -- N01-CO-124000/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 2004 Oct 15;306(5695):485-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Case Western Reserve University, University Hospitals, 2061 Cornell Road, Cleveland, OH 44106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15486300" target="_blank"〉PubMed〈/a〉
