Provided are an anti-tumor fusion protein, a preparation method therefor and an application thereof. Specifically, the fusion protein contacts a CPP element, an optional linking element, and a SH2 domain of SHP2 or SHP1 or an active fragment thereof. The obtained fusion protein has an extremely excellent anti-tumor effect.

The present invention relates to an immune cell that are engineered to overexpress cell signaling pathway modulator(s) and a use thereof. As a specific example, an immune cell expressing a fusion protein comprising a chimeric antigen receptor and a cell signaling pathway modulator(s) performs an immune response by selecting a target cancer cell by a chimeric antigen receptor expressed on a cell membrane. In this case, the cell signaling pathway modulator is overexpressed in the cytoplasm, thereby being capable of regulating the activity of an immune cell. Therefore, the fusion protein comprising a chimeric antigen receptor and cell signaling pathway modulator(s), and the immune cell engineered to overexpress the cell signaling pathway modulator(s) of the present invention can be usefully used in the treatment of cancer.

The present disclosure provides fusion proteins with improved signaling properties. Disclosed embodiments include fusion proteins that comprise an extracellular component comprising a target-binding domain, a transmembrane domain, and an intracellular component comprising a SH2 domain or a functional portion or variant thereof, and have improved signaling in response to antigen-binding, including of solid-tumor antigens with low levels of expression. Recombinant host cells expressing the fusion proteins, and polynucleotides encoding the fusion proteins, are also provided, as are compositions and methods comprising the same.

The present invention relates to multispecific antibodies, methods for their production, pharmaceutical compositions containing said antibodies and uses thereof.

The present invention provides a chimeric receptor which comprises: a ligand-binding exodomain; and an endodomain which comprises: (i) a cytokine receptor endodomain; and (ii) an intracellular T cell signalling domain.

The present invention relates to compositions and methods for generating RNA Chimeric Antigen Receptor (CAR) transfected T cells. The RNA-engineered T cells can be used in adoptive therapy to treat cancer.

Disclosed are chimeric antigen receptors, and cells modified to express one or more proteins comprising regions of a chimeric antigen receptor (CAR). The CARs comprise an antigen binding region, a transmembrane region and a CD6-derived signalling region, wherein the CD6-derived signalling region comprises a GADS binding motif and a SLP-76 binding motif. The CD6-derived signalling region may be between 20 and 60 amino acid residues in length. The CARs exhibit increased cell activation and increased target cell killing when incorporated in CAR T cells. Also disclosed are nucleic acids encoding such CARs, and collections of nucleic acids. There are also provided medical uses of the CARs, cells, or nucleic acids, and methods of treating a condition or infection.

The present invention relates to multispecific antibodies, methods for their production, pharmaceutical compositions containing said antibodies and uses thereof.
