An improved method of treating cancers with engineered T cells is described.

The present invention provides methods and compositions for generating transgenic animals, including transgenic mammals, as well as plasma cells that allow for cell surface capture of secreted immunoglobulin molecules produced endogenously in the plasma cells.

Chimeric antigen receptors containing ROR1 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.

A chimeric antigen receptor (CAR) and a gene encoding the CAR. The CAR comprises an extracellular domain capable of binding to an antigen, a transmembrane domain, and intracellular immune co-stimulatory molecule, wherein the extracellular domain comprises a D2 domain of a Slit2 protein. A chimeric antibody-expressing cell, which introduces a gene encoding the CAR into a cell so as to express the CAR on the surface of the cell. The CAR or CAR-expressing cell can be used as a cell drug for the treatment of tumor diseases. By using the CAR for engineering cells, especially T cells, the engineered T cells can specifically recognize and kill tumors, and have higher tumoricidal activity.

The present disclosure is directed to novel multispecific chimeric antigen receptor (CAR) proteins and DNA sequences encoding these proteins. The CARs comprise at least two extracellular domains fused, via a transmembrane domain to a cytoplasmic signaling domain comprising two signaling domains. The disclosure further relates to nucleic acids encoding the novel CARs, to host cells expressing the novel CARs, and to methods of using the CARs to co-stimulate effector functions in the cells and for using cells expressing the receptors for treatment of disease and viral infections. The disclosure also relates to methods of generating a recombinant T cell with reduced susceptibility to HIV infection.

The present relation relates to a transgenic Vero cell line expressing CD4 and CCR5. The present invention encompasses the preparation and purification of immunogenic compositions which are formulated into the vaccines of the present invention.

The present invention provides a chimeric antigen receptor (CAR) signalling system comprising; (i) a receptor component comprising an antigen binding domain, a transmembrane domain and a first binding domain; and (ii) an intracellular signalling component comprising a signalling domain and a second binding domain which specifically binds the first binding domain of the receptor component; wherein, binding of the first and second binding domains is disrupted by the presence of an agent, such that in the absence of the agent the receptor component and the signalling component heterodimerize and binding of the antigen binding domain to antigen results in signalling through the signalling domain, whereas in the presence of the agent the receptor component and the signalling component do not heterodimerize and binding of the antigen binding domain to antigen does not result in signalling through the signalling domain.

Modified natural killer 92 (NK-92) cells and their use in cancer therapy, in particular for the prevention or treatment of solid tumours such as sarcomas, carcinomas, melanoma and lymphoma, and non-solid tumours such as leukaemia and related disorders. Embodiments of the invention further relate to the use of the modified NK-92 cells for in vitro diagnosis, diagnostics and/or screening, methods for the preparation of a modified NK-92 that is specific for a target antigen of a target cell in a subject, and to an expression vector, comprising the nucleic acid sequences of an antigen-specific functional T cell receptor (TCR), CD3, CD4 and/or CD8.

Provided herein are, inter alia, CD6 targeting CAR-T cell compositions and methods useful for treating autoimmune diseases (e.g., Type I diabetes).

A trifunctional molecule comprising a target-specific ligand, a ligand that binds a protein associated with the TCR complex and a T cell receptor signaling domain polypeptide is provided. The ligand that binds a protein associated with a TCR complex is UCHT1 with a Y177 mutation. Engineering T cells with this novel receptor engenders antigen specific activation of numerous T cell functions, including cytokine production, degranulation and cytolysis.
