Abstract: A CD20-OR-CD19 chimeric antigen receptor (CAR) protein construct is provided. Also provided are nucleic acids encoding the CD20-OR-CD19 CAR; and methods of use, e.g. in the treatment of B cell malignancies. The CD20-OR-CD19 CAR of the invention is a bispecific CAR that can trigger T-cell activation upon detection of either CD19 or CD20 (or both). It is a single molecule that confers two-input recognition capability upon human T cells engineered to stably express this CAR.

Abstract: Compositions and methods are provided for the cell-mediated targeted killing of diseased cells based on the presence of an intracellular antigen, rather than a surface-bound marker. The targeting cells are modified to express a cytotoxic protein that is delivered into a targeted cell, and after delivery is selectively activated by the presence of a cytoplasmic protein of interest. In one embodiment of the invention, the cytotoxic molecule is a Granzyme B (GrB) polypeptide. In the compositions of the invention, GrB is modified to render its cytotoxic enzymatic functions inactive, until the presence of an intracellular antigen unlocks the GrB molecule to enable enzymatic activities.

Abstract: The present application relates to nucleic acids that encode a RNA switch responsive to a ligand that can control the expression of a gene product that affects the cell fate determination of a mammalian cell are provided. In some embodiments, the system can be used to control the proliferation or activation of mammalian cells in response to a ligand that can be provided exogenously to the mammalian cell or can be produced by the mammalian cell. The system can be used to promote the growth or proliferation of human T cells in response to an exogenous ligand applied to the cells. In one embodiment, the system detects the ligand through a RNA aptamer that modulates expression of a gene product through activation or inactivation of a ribozyme that modulates expression of the gene product.
