Publication number: 20230220070Abstract: The present invention addresses the problem of providing a novel therapeutic agent for treating patients with anti NMDAR encephalitis. Patients with an anti NMDAR encephalitis have a pathogenic anti-human NR1 antibody that induces internalization of NMDAR on cell surface. As a result, NMDAR function is weakened in the patients' brain. The present inventors found that the one-armed anti-human NR1 antibody according to the present invention binds to NR1 competitively with the pathogenic anti-human NR1 antibody and inhibits the internalization of NMDAR by the pathogenic anti-human NR1 antibody to thereby exhibit therapeutic effect on anti NMDAR encephalitis.Type: ApplicationFiled: November 17, 2022Publication date: July 13, 2023Inventors: Satoshi KUBO, Atsuo KANNO, Daisuke YAMAJUKU, Takuya KITO, Masashi MAEDA, Takuma MIHARA
