Described herein are immunomodulatory fusion proteins containing an extracellular binding domain and an intracellular signaling domain, wherein binding of a target can generate a modulatory signal in a host cell, such as a T cell. Some immunomodulatory fusion proteins as described comprise a SIRP extracellular component and hydrophobic and intracellular components comprising transmembrane and/or signaling domains of a CD28, respectively. Such fusion proteins are capable of delivering a positive or costimulatory signal in response to a binding event that in a natural setting would result in an inhibitory signal. Uses of immune cells expressing such immunomodulatory fusion proteins to treat certain diseases, such as cancer or infectious disease, are also described.

The present invention relates to chimeric antigen receptors (CARs) directed to cells expressing a dysfunctional or non-functional P2X purinoceptor 7 receptor. Further provided are methods of targeting neoplastic cells and tumours expressing a dysfunctional or non-functional P2X purinoceptor 7 receptor and methods of treating and preventing cancer is a subject.

Current invention relates to a polynucleotide encoding activating chimeric receptors comprising engineered Natural Killer Group 2 member C (NKG2C) having enhanced affinity for HLA class I histocompatibility antigen alpha chain E (HLA-E)/peptide complex or an extracellular receptor domain of NKG2A coupled to an effector domain. It also relates to NK cells expressing such constructs and the use of these NK cells to induce cytotoxicity. It further exemplifies that the NK cells expressing polynucleotide encoding NKG2C (SIIS)/CD94/DAP12 or NKG2C/CD94/4-1 BB/CD3z showed enhanced NK cytotoxicity against cancer cells.

Provided herein are a recombinant chimeric antigen receptor (CAR) fusion protein, a method of modifying an immune cell into a CAR immune cell by treating the immune cell with the recombinant CAR fusion protein, and a method of treating cancer by administering the CAR immune cell to a subject in need thereof.

Provided are receptor tyrosine kinase-like orphan receptor 1 (ROR1)-binding molecules, in particular, to human antibodies specific for ROR1, including antibody fragments. The present disclosure further relates to recombinant receptors, including chimeric antigen receptors (CARs) that contain such antibodies or fragments, and polynucleotides that encode the antibodies, antigen-binding fragments or receptors specific for ROR1. The disclosure further relates to genetically engineered cells, containing such ROR1-binding proteins and receptors, and related methods and uses thereof in adoptive cell therapy.

Described herein, are the extended and newly discovered novel formulations of FL118 for cancer treatment to preclude, eliminate or reverse cancer phenotypes and treatment resistance.

Disclosed herein are polynucleotides comprising a nucleotide sequence encoding an AP-1 transcription factor (i.e., c-Jun). In some aspects, the nucleotide sequence is codon-optimized. In some aspects, the polynucleotides comprise one or more additional nucleotide sequences encoding a linker, signal peptide, antigen-binding domain, spacer, transmembrane domain, costimulatory domain, intracellular signaling domain, truncated EGFR, and combinations thereof. Also disclosed herein are cells, vectors, and pharmaceutical compositions comprising such polynucleotides. The use of such polynucleotides, cells, vectors, and pharmaceutical compositions to treat a disease or disorder (e.g., cancer) is also provided.

Genetically engineered hematopoietic cells such as hematopoietic stem cells having one or more genetically edited genes of lineage-specific cell-surface proteins and therapeutic uses thereof, either alone or in combination with immune therapy that targets the lineage-specific cell-surface proteins.

The invention relates to novel chimeric antigen (CAR) mRNA molecules, the methods of generating the molecules and methods of treating cancer with the molecules.

Provided herein are antibodies and antigen-binding fragment thereof targeting CLL1, and chimeric antigen receptors (e.g., monovalent CAR, and multivalent CAR including bi-epitope CAR) having one or more anti-CLL1 antigen-binding fragments thereof. Further provided are engineered immune effector cells (e.g., T cells) expressing the chimeric antigen receptors and methods of use thereof.
