Astrocytes, star-shaped cells found around nerve cells, make an inflammation driver of neuromyelitis optica spectrum disorder (NMOSD) called interleukin-6 (IL-6) in part by gearing up a chain of reactions involving nuclear factor kappa B, or NF-kappaB, according to a study in rat cells. Researchers also observed that by blocking…

People with neuromyelitis optica spectrum disorder (NMOSD), but lacking anti-AQP4 and anti-MOG antibodies, show no signs of damage to astrocytes — nervous system cells attacked in NMOSD — when compared to those with anti-AQP4 antibodies. Those findings from a recent study suggest that the mechanisms underlying NMOSD symptoms in…
A system that stages neuromyelitis optica spectrum disorder (NMOSD) based on damage to astrocytes — the specific brain cells that are attacked in NMOSD — was recently developed by a team of researchers in Japan. While more work is needed, the system identifies four stages, largely based on astrocytopathy…
In most people with neuromyelitis optica spectrum disorder (NMOSD), autoantibodies against aquaporin-4 (AQP4) coordinate a complex series of immune activities that drive the disease. Better understanding of these disease-causing mechanisms may help in efforts to find new treatments for NMOSD patients. These mechanisms were explained in the lecture, “…
The autoimmune biomarker CH50 was directly impacted by treatment with Soliris (eculizumab) in three people with neuromyelitis optica spectrum disorder (NMOSD), a case report has shown. According to researchers, this suggests that CH50 may be a useful…
