Abstract: The present invention provides a viral vector comprising a nucleotide sequence encoding a complement protein, wherein the nucleotide sequence is operably linked to a podocyte-specific promoter and/or the viral vector is capable of specifically transducing podocytes.

Abstract: The present invention provides a cell which comprises; (i) a chimeric antigen receptor (CAR) or a transgenic T-cell receptor (TCR); and (ii) a polypeptide capable of co-localizing a beta-2 microglobulin component of a MHC class I molecule with an intracellular signalling domain within the cell.

Abstract: The present invention provides a cell comprising first and second chimeric antigen receptors (CARs), which bind to different antigens, wherein the first CAR binds to Transmembrane activator and calcium modulator and cyclophilin ligand (CAML) interactor (TACI). The present invention also provides a cell comprising a tan CAR comprising first and second antigen-binding domains which bind to different antigens, wherein the first antigen binding domain binds the antigen Transmembrane activator and calcium modulator and cyclophilin ligand (CAML) interactor (TACI). The present invention further provides corresponding nucleic acid sequences and/or constructs, kits and vectors comprising said nucleic acid sequences and/or constructs, molecules and methods for making such cells. The cells may be used in cellular immunotherapy approaches for treating diseases such as multiple myeloma.
