Beschreibung:
Although many T cells carry two in-frame V alpha rearrangements, the products of both V alpha rearrangements have never been shown simultaneously on the surface of normal cells. With the use of monoclonal antibodies to V alpha 2, V alpha 12, and V alpha 24, up to one-third of mature T cells expressed two V alpha chains as part of two functional and independent T cell receptors (TCRs). Thus, the "one cell, one receptor" rule does not apply to a large subset of alpha beta T cells. Cells that belong to this dual TCR subset may be specific for a broader range of antigens than cells with a single receptor, which may be important for autoimmunity and alloreactivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Padovan, E -- Casorati, G -- Dellabona, P -- Meyer, S -- Brockhaus, M -- Lanzavecchia, A -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):422-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Basel Institute for Immunology, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8211163" target="_blank"〉PubMed〈/a〉
