A small percentage of human T lymphocytes, predominantly CD8+ T cells, express receptors for HLA class 1 molecules of natural killer type (NK-R) that are inhibitory for T-cell antigen receptor(More)
Natural killer (NK) cells express surface receptors for defined groups of HLA class I alleles. The specific interaction between these receptors and HLA class I molecules expressed on target cells(More)
A fraction of human T lymphocytes, predominantly CD8+, express receptors for HLA class I molecules typical of natural killer cells (natural killer receptors or NKRs) that inhibit T cell(More)
Fresh postnatal thymocyte cell suspensions were directly cloned under limiting dilution conditions with either phytohemagglutinin or toxic shock syndrome toxin-1 (TSST-1), a bacterial superantigen.(More)
In recent years, the molecular mechanism by which natural killer cells lyze, or fail to lyze, different target cells has been elucidated. Natural killer cells express receptors which recognize MHC(More)
