  • Patent number: 5871997
    Abstract: Methods and compositions are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The reduction of levels of galactose alpha (1,3) galactosyl epitopes on the retroviral vector particles and/or the blockade of antibody binding to such epitopes have been found to render the particles less sensitive to inactivation by complement mediated mechanisms, and to thus allow transduction in the presence of complement containing body fluids. Means are provided for obtaining such reductions.

  • Patent number: 5847082
    Abstract: Nucleic acid sequences encoding chimeric proteins that comprise a functional portion of a parent terminal complement inhibitor, such as CD59, and a heterologous transmembrane domain are provided. The parent terminal complement inhibitor is modified to inactivate its GPI signal sequence. The heterologous transmembrane domain serves to anchor the chimeric protein to the cell membrane without substantially interfering with the complement inhibitor activity of the terminal complement inhibitor. The nucleic acid sequences and encoded chimeric proteins can be used to protect cells from complement attack.

  • Patent number: 5821117
    Abstract: DNA sequences encoding a porcine Gal.alpha.(1,3) galactosyl transferase and clones containing such sequences are provided. The porcine Gal.alpha.(1,3) galactosyl transferase produces the Gal.alpha.(1,3)Gal epitope on the surfaces of porcine cells. This epitope is recognized by human anti-Gal.alpha.(1,3)Gal antibodies which are responsible for hyperacute rejection of xenotransplanted pig cells, tissues and organs.

  • Patent number: 5643770
    Abstract: Modified retroviral vector particles and modified retroviral producer cells producing such particles are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The modifications involve genetic alterations to effect the expression by these cells and particles of complement inhibitor activity. The genetic alterations involve the introduction of nucleic acid expression constructs directing the expression of retroviral SU(gp70)/complement inhibitor chimeric proteins into cells from which the producer cells are derived.

  • Patent number: 5627264
    Abstract: Chimeric complement inhibitor proteins are provided which include a first functional domain (first amino acid sequence) having C3 inhibitory activity and a second functional domain (second amino acid sequence) having C5b-9 inhibitory activity. The first functional domain is amino terminal to the second functional domain. In this way, the chimeric protein exhibits both C3 and C5b-9 inhibitory activity. The other orientation, i.e., the orientation in which the second amino acid sequence is amino terminal to the first amino acid sequence, only produces C3 inhibitory activity. Nucleic acid molecules encoding such proteins are also provided.

  • Patent number: 5580766
    Abstract: Retroviral vector particles are provided which contain: 1) oncoretroviral gag, pol, and env proteins, including an oncoretroviral gag capsid protein which has been mutated so as to contain a nuclear localization signal (NLS) sequence; and 2) at least one exogenous gene. The particles can be used to transduce non-proliferating cells, including stem cells and neurons. The presence of the NLS sequence allows the at least one exogenous gene to enter into the nucleus of a target cell, thus allowing integration of the gene into the genome of the target cell.
