CLONING, EXPRESSION AND CHARACTERISATION OF A GENE EXPRESSED IN TUMOUR CELLS AND INVOLVED IN THE REGULATION OF THE IMMUNE RESPONSE

摘要

The invention concerns the identification and the characterisation of a novel gene expressed in tumour cells and involved in the regulation of the immune response, the cloning and the characterisation of its cDNA and the corresponding polypeptides. The invention also concerns vectors containing a nucleic acid coding for said gene, cells transformed by said vectors and diagnostic methods and selection methods of a chemical or biological compound capable of directly or indirectly interacting with a nucleic acid or a polypeptide of the invention. The invention further concerns compounds for treating immune pathologies, in particular autoimmune diseases and cancer.
