20240002464 · 2024-01-04 ·

The present invention provides a T cell receptor (TCR) capable of specifically binding to HPV 16 E6 antigen short peptide complex TIHDIILECV-HLA A0201. Moreover, an effector cell transducing the TCR of the present disclosure also has a strong killing function. Such TCR can be used separately or in combination with other therapeutic agents, and can also be used in adoptive cellular immunotherapy to target a tumor cell presenting the complex TIHDIILECV-HLA A0201.

The disclosure relates to immune cells comprising systems of two engineered receptors each having a ligand binding domain, collectively designed to target cells identified by loss of heterozygosity and used to treat a disease or disorder, for example, cancer. The disclosure provides immune cells expressing two engineered receptors, methods of making same, and polynucleotides and vectors encoding same.

ANTIGEN SPECIFIC T CELLS AND METHODS OF MAKING AND USING SAME

In various embodiments, the present disclosure provides T cell compositions comprising T cells that encode and/or express a T cell receptor (TCR) that binds to a neoantigen associated with a subject's cancer, and are useful for adoptive immunotherapy. Also disclosed are methods for making and/or using T cell compositions described herein.

CHIMERIC ANTIGEN RECEPTOR COMPRISING NOVEL CO-STIMULATORY DOMAIN AND USE THEREOF

Provided is a chimeric antigen receptor, comprising a ligand-binding domain, a transmembrane domain, a co-stimulatory domain, and an intracellular signaling domain. The co-stimulatory domain comprises an intracellular region of an NK-activated receptor or a ligand thereof. Also provided are an engineered immune cell comprising the chimeric antigen receptor and a use thereof in treatment of diseases, such as cancers, autoimmune diseases, and infections.
