  • Publication number: 20220016176
    Abstract: The present invention provides an expression vector for preventing or inhibiting HIV entry, fusion or replication in mammalian cells. In particular, the invention provides a recombinant retroviral vector that encodes an inhibitor of a HIV co-receptor, such as CCR5 or CXCR4, and a protein that inhibits HIV fusion to target cells and/or HIV replication. Pharmaceutical compositions comprising such constructs and methods of use thereof to prevent or treat HIV infection in a patient are also disclosed.

  • Publication number: 20180305435
    Abstract: The HIV-specific cytotoxic T lymphocyte (CTL) response is a critical component in controlling HIV replication and is an important part of the ultimate failure to eradicate the virus. Disclosed herein are methods for genetically enhancing the HIV-specific CTL response to allow long-term viral suppression or viral clearance. Human hematopoietic stem cells (HSCs) were genetically modified such that they differentiate into mature CTLs that will kill HIV infected cells. As disclosed herein, the functional effector cells are not human leukocyte antigen (HLA)-restricted. As disclosed herein, stem cells are transduced with non-HLA restricted chimeric antigen receptors (CARs) that allow the recognition of HIV or HIV-infected cells when expressed by a CTL. These CARs are hybrid molecules that contain an extracellular HIV recognition domain and an intracellular TCR-zeta signaling domain. The CTL response may be enhanced through the targeting of T cell inhibitory receptors.

  • Patent number: 9902652
    Abstract: Provided herein are methods comprising a) treating a slag solid or carbide lime suspension with an ammonium salt in water to produce an aqueous solution comprising calcium salt, ammonium salt, and solids; b) contacting the aqueous solution with carbon dioxide from an industrial process under one or more precipitation conditions to produce a precipitation material comprising calcium carbonate and a supernatant aqueous solution wherein the precipitation material and the supernatant aqueous solution comprise residual ammonium salt; and c) removing and optionally recovering ammonia and/or ammonium salt using one or more steps of (i) recovering a gas exhaust stream comprising ammonia during the treating and/or the contacting step; (ii) recovering the residual ammonium salt from the supernatant aqueous solution; and (iii) removing and optionally recovering the residual ammonium salt from the precipitation material.
