  • 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.

  • Publication number: 20170059595
    Abstract: In various embodiments, a new, robust fluorometric cell-free biochemical assay that measures HDL redox activity (HRA) is provided. In certain embodiments the assay is based on the oxidation of the fluorochrome AMPLEX® RED in the presence of HRP. HRA correlated with previously validated cell-based (r=0.47, p<0.001) and cell-free assays (r=0.46, p<0.001). HRA measurement identified samples with dysfunctional HDL in established animal models of atherosclerosis and Human Immunodeficiency Virus (HIV) patients. Using an immunoaffinity method for capturing HDL the utility of this novel assay for measuring HRA in a high throughput format was demonstrated. HRA measurements correlated significantly with measures of cardiovascular disease such as carotid intima media thickness (r=0.35, p<0.01) and subendocardial viability ratio (r=?0.21, p=0.05) and physiological parameters such as metabolic and anthropometric parameters (p<0.05).

  • Patent number: 9228007
    Abstract: Disclosed herein are recombinant human progenitor cells, engineered human thymocytes, and engineered human T cells. The recombinant human progenitor cells are made by transducing a human hematopoietic stem cell with a vector having a nucleic acid molecule which encodes a human T cell receptor specific to a virus, such as Human Immunodeficiency Virus, or an epitope thereof. The recombinant human progenitor cells differentiate and mature into the engineered human thymocytes and the engineered human T cells. Also disclosed herein are methods of inhibiting, reducing or treating a viral infection in a subject, such as a human subject, which comprises administering recombinant human progenitor cells, engineered human thymocytes, and/or engineered human T cells to the subject.
