    摘要: The present technology relates to a method for causing cell death. The method comprises the step of genetically manipulating chromosomal DNA of a cell such as by, for example, using a recombinase system, to lose an autosome during cell division and wherein loss of the autosome results in death of the cell. The technology also relates to a method for selective ablation of proliferative cells within a population of cells.

    摘要: Nucleic acids encoding novel CTLA4/CD28 ligands which costimulate T cell activation are disclosed. In one embodiment, the nucleic acid has a sequence which encodes a B lymphocyte antigen, B7-2. Preferably, the nucleic acid is a DNA molecule comprising at least a portion of a nucleotide sequence shown in FIG. 8, SEQ ID NO:1 or FIG. 14, SEQ ID NO:23. The nucleic acid sequences of the invention can be integrated into various expression vectors, which in turn direct the synthesis of the corresponding proteins or peptides in a variety of hosts, particularly eukaryotic cells, such as mammalian and insect cell culture. Also disclosed are host cells transformed to produce proteins or peptides encoded by the nucleic acid sequences of the invention and isolated proteins and peptides which comprise at least a portion of a novel B lymphocyte antigen. Proteins and peptides described herein can be administered to subjects to enhance or suppress T cell-mediated immune responses.
