ENGINEERING ANTIVIRAL T CELL IMMUNITY THROUGH STEM CELLS AND CHIMERIC ANTIGEN RECEPTORS
摘要
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.
