Description:
Identification and characterization of antigen-specific T lymphocytes during the course of an immune response is tedious and indirect. To address this problem, the peptide-major histocompatability complex (MHC) ligand for a given population of T cells was multimerized to make soluble peptide-MHC tetramers. Tetramers of human lymphocyte antigen A2 that were complexed with two different human immunodeficiency virus (HIV)-derived peptides or with a peptide derived from influenza A matrix protein bound to peptide-specific cytotoxic T cells in vitro and to T cells from the blood of HIV-infected individuals. In general, tetramer binding correlated well with cytotoxicity assays. This approach should be useful in the analysis of T cells specific for infectious agents, tumors, and autoantigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altman, J D -- Moss, P A -- Goulder, P J -- Barouch, D H -- McHeyzer-Williams, M G -- Bell, J I -- McMichael, A J -- Davis, M M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1996 Oct 4;274(5284):94-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Stanford University School of Medicine, Stanford, CA 94305-5428, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8810254" target="_blank"〉PubMed〈/a〉
