CHIMERIC AUTOANTIBODY RECEPTOR (CAAR) THAT BINDS AUTOANTIBODIES TARGETING THE CENTRAL NERVOUS SYSTEM IN NEUROLOGICAL AUTOIMMUNE DISEASE

A chimeric autoantibody receptor (CAAR) that enables targeting of an immune cell to autoantibody producing B cells. The CAAR includes an autoantigen or fragment thereof that is bound by autoantibodies associated with neurological autoimmune disease primarily targeting the central nervous system. Also disclosed is a nucleic acid molecule encoding a chimeric autoantibody receptor (CAAR), the nucleic acid sequence encoding an autoantigen or fragment thereof that is bound by autoantibodies associated with a neurological autoimmune disease primarily targeting the central nervous system, a transmembrane domain, and an intracellular signaling domain, a vector comprising a nucleic acid molecule encoding a chimeric autoantibody receptor (CAAR), a genetically modified immune cell comprising the nucleic acid molecule encoding the CAAR and use of the immune cell in the treatment or prevention of a neurological autoimmune disease primarily targeting the central nervous system, such as an autoimmune encephalopathy or encephalomyelopathy, preferably anti-NMDAR encephalitis.
