Herein described is a method for treating cancer in a subject by administering a human umbilical cord perivascular cell (HUCPVC) that has been genetically modified to increase the expression of an oligonucleotide or a polypeptide such as an anti-cancer antibody.

The present invention relates to genetically modified B cells and their uses thereof, for example, for the treatment of a variety of diseases and disorders, including cancer, heart disease, inflammatory disease, muscle wasting disease, neurological disease, and the like. In certain embodiments, the invention relates to an isolated modified B cell (CAR-B cell), capable of expressing a chimeric receptor (CAR-B receptor), wherein said chimeric receptor comprises (a) an extracellular domain; (b) a transmembrane domain; and (c) a cytoplasmic domain that comprises at least one signaling domain. In various embodiments, the invention comprises an isolated modified B cell, wherein said B cell is capable of expressing and secreting a payload, wherein the payload is not naturally expressed in a B cell or is expressed at higher levels than is naturally expressed in a B cell. In various embodiments, the payload is an antibody or fragment thereof.

The application describes a T-cell expressing a chimeric antigen receptor (CAR T-cell) containing superparamagnetic iron-based particles (loaded CAR T-cell) for use in treating a tumor. Said loaded CAR T-cell exhibits a reduced cytokine release upon binding to a cell of the tumor expressing an antigen being recognized by the CAR of the CAR T-cell, compared to a CAR T-cell not containing superparamagnetic iron-based particles (unloaded CAR T-cell) under the same conditions. Furthermore, an in vitro method of generating a CAR T-cell containing superparamagnetic iron-based particles is described, whereby such loaded CAR T-cells are generated.

The present invention provides an antibody against glypican-3 (GPC3) and application thereof, and the antibody comprises a single chain antibody and humanized antibody.

Described herein are immunoresponsive cells engineered to express cytokines, chimeric receptors, and synthetic transcription factor systems. Also described herein are nucleic acids, cells, and methods directed to the same.

Provided is a method of activating a recombinant immune cell expressing a synthetic receptor comprising an intracellular domain derived from killer cell immunoglobulin-like receptor 4 (KIR2DL4). Synthetic receptors described herein allow for the activation of recombinant immune cells against an antigen of interest without the deleterious effects of immune cell hyperactivation by existing CARs. The recombinant immune cells can thus be used to in the treatment of cancers or infectious diseases in subjects in need thereof, while limiting the hyperactivation of an immune response associated with traditional recombinant cell-based therapies.

Disclosed herein are methods of treating a subject exhibiting a solid tumor that expresses Glypican-3 (GPC3). The methods typically utilize g GPC3 chimeric antigen receptor immunoresponsive cells to a subject in need thereof to effect killing of tumor cells.

Some embodiments of the present disclosure are directed to methods that include delivering to a subject a papillomavirus particle or soluble papillomavirus protein that targets a tumor, and delivering to the subject an immune cell expressing a receptor that binds to a surface antigen of the papillomavirus particle or soluble papillomavirus protein, respectively.

The present invention pertains to immunology, biomedicine field, specifically relates to a method for prevention or treatment of one or more of diseases relevant to the protein in the protein-cell conjugate, malignant tumors, infectious diseases caused by pathogenic microorganisms and autoimmune diseases. The method includes a step of administering to a subject in such need a prophylactically or therapeutically effective amount of a protein-cell conjugate, the said protein-cell conjugate is a conjugate formed by covalently linking a protein and a cell to a linker, respectively; the cell has free sulfhydryl groups distributed on its surface, when the cell is not linked to the linker; the linker is derived from a bifunctional cross-linking agent, and the bifunctional cross-linking agent comprises both a group capable of reacting with an amino group and a group capable of reacting with a sulfhydryl group.
