Abstract: Provided herein are compositions with an augmented capacity to mediate ADCC. These compositions include chimeric NK cells—called “Nukes” (NK Enhancement Strategy) that express CD64 Fc receptor from an exogenous nucleic acid molecule, the NK cells having antibodies bound thereto. Methods of using these cells for treatment of HIV, cancer, SARS-COV-2, and other diseases are provided.

Abstract: The present invention relates to engineered cells expressing a fusion protein comprising a peptide fusion inhibitor and a CXCR4 protein that lacks signaling activity. Also provided are methods of suppressing, inhibiting, preventing or treating a HIV infection in a subject in need thereof using the engineered cells.

Abstract: The present invention provides methods and compositions for converting a T cell into a cell that exhibits at least one regulatory T cell phenotype. The converted T cell is generated by contacting a T cell with a cell that is modified to comprise an agent capable of activating PD1 signaling in a T cell. The converted T cell is useful for preventing, suppressing, blocking or inhibiting an immune response. For example the converted T cell is useful for preventing rejection of a transplanted tissue in a human or other animal host, or protecting against graft versus host disease. The converted T cell can also be used to treat autoimmune diseases.

Abstract: The present invention provides methods and compositions for converting non-Tregs into Tregs. The converted Tregs are referred to as inducible Tregs (iTregs). The iTregs are useful for preventing, suppressing, blocking or inhibiting an immune response. For example the iTregs are useful for preventing rejection of a transplanted tissue in a human or other animal host, or protecting against graft vs host disease. The iTregs can also be used to treat autoimmune diseases.
