Description:
An important feature of the human immune system is the ability of T cells to respond to small quantities of antigen. Class II major histocompatibility complex (MHC)-restricted T cells that expressed a costimulatory natural killer (NK) cell receptor for class I MHC proteins were cloned. In the presence of low doses of superantigen, the proliferative response of these T cell clones was three- to ninefold greater when the T cells were costimulated by way of the NK receptor. Thus, the action of costimulatory NK receptors on T cells may play a significant role in initiating and sustaining immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mandelboim, O -- Davis, D M -- Reyburn, H T -- Vales-Gomez, M -- Sheu, E G -- Pazmany, L -- Strominger, J L -- CA 47554/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 Dec 20;274(5295):2097-100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Harvard University, 7 Divinity Avenue, Cambridge, MA 02138, USA. jlstrom@fas.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8953044" target="_blank"〉PubMed〈/a〉
