Research and progress on biomarkers of neuromyelitis optica spectrum disorders

Abstract

Neuromyelitis optica spectrum disorders (NMOSD) are a demyelinating disorder of the central nervous system based on the involvement of the optic nerve and/or spinal cord. The disease is characterized by high recurrence and disability. NMOSD is mainly diagnosed by AQP4-IgG and MOG-IgG. However, there are still some patients with negative or undetermined double-antibody, and AQP4-IgG and MOG-IgG cannot indicate the clinical disease activity. Therefore, it is urgent to explore interesting biomarkers in serum and cerebrospinal fluid to promote early clinical diagnosis and/or as a target for diagnosis and treatment. This article summarized the research progress in serum and cerebrospinal fluid biomarkers of astrocytes, neurons, myelin sheath, and other damage after the onset of NMOSD. Besides the value of microglial activation-related proteins in the diagnosis and treatment of NMOSD was prospected, so as to promote the research progress of NMOSD.
