LLT-1 antibodies with new functional properties

摘要

The present invention relates to monoclonal antibodies that are capable of specifically binding to lectin-like transcript 1 (LLT1), to polynucleotides encoding such antibodies and to cells that express such antibodies. Antibodies of the invention have utility in the treatment of autoimmune diseases and cancer, in which LLT1-and CD161-expressing cells play a role in disease pathogenesis.

主权项
