Title:
TREATMENT AND DIAGNOSIS OF CANCER OR INFECTIOUS DISEASE USING RECOGNITION MECHANISM OF T CELL RECEPTOR
Document Type and Number:
WIPO Patent Application WO/2018/026018
Kind Code:
A1
Abstract:
Provided is a method for treating and diagnosing cancer or an infectious disease using the recognition mechanism of a T cell receptor. An NK cell function enhancer, said NK cell function enhancer comprising as an active ingredient a T cell receptor chimeric protein which is a fused protein consisting of a variable region of a T cell receptor capable of recognizing a cancer-specific antigen or a variable region of a T cell receptor capable of recognizing an antigen specific to a pathogen causative of an infectious disease and the Fc region of immunoglobulin, which binds to an MHC molecule complex of cancer cells to induce down modulation of MHC class 1 molecule complex and thus enables NK cells to recognize the cancer cells and kill the same; and an NK cell function enhancer which imparts to NK cells an ability to recognize cancer cells expressing an MHC class 1 molecule or infected cells infected with a pathogen causative of an infectious disease and thus enables the NK cells to kill the cancer cells or the infected cells by the T cell receptor chimeric protein-dependent cytotoxicity (TDCC) activity.
