Higher blood levels of the glial fibrillary acidic protein (GFAP) are significantly associated with shrinkage in certain brain regions of people with neuromyelitis optica spectrum disorder (NMOSD) who have antibodies against the AQP4 protein, a study showed. This association was not observed in people with myelin oligodendrocyte glycoprotein antibody-associated…

The activity of an immune-regulating protein is significantly lower just before or during a relapse in people with neuromyelitis optica spectrum disorder (NMOSD), a recent study has found. This discovery could lead to new ways to monitor disease activity and develop treatments. The protein, called the aryl hydrocarbon receptor…

Two blood markers — neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) — provide complementary clinical information about neuromyelitis optica spectrum disorder (NMOSD), a review study highlights. “Based on the results of several studies, both NfL and GFAP are considered to have their own strengths as clinical…

People with neuromyelitis optica spectrum disorder (NMOSD) have a significantly higher neutrophil-to-lymphocyte ratio (NLR), an immune cell-based marker of inflammation, than healthy people, a review study showed. A higher NLR ratio was also significantly associated with a greater chance of relapse, severe disability, and new or enlarging lesions on…

People with neuromyelitis optica spectrum disorder (NMOSD) have elevated levels of the pro-inflammatory protein AIMP1 in the bloodstream, and higher levels seem to correlate with worse disability, a study showed. These AIMP1 levels dropped markedly after anti-inflammatory therapy, but still remained higher among patients in remission than in people…

Blood levels of two proteins, GFAP and neurofilament light chain (NfL), may help predict the course of neuromyelitis optica spectrum disorder (NMOSD), according to new research. Findings also suggest that many NMOSD patients have evidence of brain lesions with active inflammation without any associated symptoms, which indicates that disease…
