Autoimmune disease

Multiple sclerosis (MS)

Prostate-specific membrane antigen (PSMA; FOLH1; GCPII)

Human and mouse studies suggest inhibiting GCPII could help treat cognitive impairments associated with MS. In newly diagnosed patients with relapsing-remitting MS, magnetic resonance spectroscopy of brains showed that low levels of N-acetylaspartylglutamate (NAAG) correlated with cognitive dysfunction. In mice with experimental autoimmune encephalomyelitis (EAE), increasing levels of NAAG with a GCPII inhibitor did not affect physical disease symptoms but increased cognitive functions, including memory and learning, compared with vehicle control. Next steps include identifying new GCPII inhibitors or delivery vehicles.
