    摘要: The present invention features novel methods for generating cell lines and mammals with site-specific genetic modifications of interest. The methods involve homologous recombination between an artificial chromosome having a modification of interest and an endogenous chromosome of a cell. The resulting modified cells can be used in standard methods to generate genetically modified mammals. These mammals can be used in a variety of screening methods to identify compounds useful for the treatment or prevention of disease. Additionally, cells that have been modified to eliminate a mutation associated with a disease can be transplanted into patients for the treatment of a disease.

    摘要: A simple and highly efficient method for cloning cDNAs including CD27 (SEQ ID NO:28) from mammalian expression libraries based on transient expression in mammalian host cells has been discovered. Novel expression vectors allowing highly efficient construction of mammalian cDNA libraries are disclosed. The cloning method of the invention which has been used to clone genes for cell surface antigens of human lymphocytes, has general application in gene cloning. Cell surface antigens cloned according to the present invention have been purified, and the nucleotide and amino acid sequences determined. These antigens have diagnostic and therapeutic utility in immune-mediated infections in mammals, including humans.

    摘要: Disclosed is a method of directing a cellular immune response against an HIV-infected cell in a mammal involving administering to the mammal an effective amount of therapeutic cells which express a membrane-bound, proteinaceous chimeric receptor comprising (a) an extracellular portion which includes a fragment of CD4 which is capable of specifically recognizing and binding the HIV-infected cell but which does not mediate HIV infection and (b) an intracellular portion which is capable of signalling the therapeutic cell to destroy the receptor-bound HIV-infected cell. Also disclosed is a second method of treating HIV in a mammal involving administering to the mammal an effective amount of therapeutic cells expressing a membrane-bound, proteinaceous chimeric receptor comprising an extracellular portion which includes a fragment of CD4 which is capable of specifically recognizing and binding the HIV-infected cell but which does not mediate HIV infection. Also disclosed are cells which express the chimeric receptors and DNA and vectors encoding the chimeric receptors.
