Beschreibung:
The relation between an antigenic peptide that can stimulate a mature T cell and the natural peptide that promoted selection of this cell in the thymus is still unknown. An experimental system was devised to address this issue in vivo-mice expressing neopeptides in thymic stromal cells after adenovirus-mediated delivery of invariant chain-peptide fusion proteins. In this system, selection of T cells capable of responding to a given antigenic peptide could be promoted by the peptide itself, by closely related analogs lacking agonist and antagonist activity, or by ostensibly unrelated peptides. However, the precise repertoire of T cells selected was dictated by the particular neopeptide expressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakano, N -- Rooke, R -- Benoist, C -- Mathis, D -- New York, N.Y. -- Science. 1997 Jan 31;275(5300):678-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Genetique et de Biologie Moleculaire et Cellulaire (INSERM, CNRS, Universite Louis Pasteur), 1 rue Laurent Fries, 67404 Illkirch, C.U. de Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9005856" target="_blank"〉PubMed〈/a〉
