In demyelinating diseases such as multiple sclerosis, one of the treatment strategies includes remyelination using oligodendrocyte precursor cells (OPC). Catalpol, the extract of radix rehmanniae, is neuroprotective. Using an OPC culture model, we showed that 10 μM catalpol promotes OPC proliferation, cell migration and differentiation into mature oligodendrocytes. The 10 μM catalpol displayed ...
Demyelinating diseases alter myelin or the coating surrounding most nerve fibers in central and peripheral nervous systems. The grouping of human system demyelinating disorders today includes multiple sclerosis (MS) neuromyelitis optica spectrum (NMOSD) as distinct disease categories. Each is caused by a complex combination genetic environmental variables, many involving an autoimmune response....
Myasthenia gravis (MG) is an autoimmune disease characterized by fluctuating muscle weakness, caused by impaired neuromuscular transmission. Patients with MG can present other autoimmune diseases in association, commonly hypo or hyperthyroidism. The association of MG to demyelinating disease is rare and has been described before. We report on three Brazilian patients with MG that presented dist...
OBJECT Intrinsic diffuse brainstem tumors and demyelinating diseases primarily affecting the brainstem can share common clinical and radiological features, sometimes making the diagnosis difficult especially at the time of first clinical presentation. To explore the potential usefulness of new MRI sequences in particular diffusion tensor imaging fiber tracking in differentiating these two patho...
tral nervous system demyelination have been increasingly recognized in children. Moreover, a much higher proportion of children (as compared to adults) suffer from a monophasic (and not chronic) demyelinating event such as acute disseminated encephalomyelitis or isolated optic neuritis, and transverse myelitis, often post-infectious. Differentiation between such acute monophasic illnesses and a...
Oligodendrocytes and myelin play essential roles in the vertebrate central nervous system. Demyelination disrupts saltatory nerve conduction, leading to axonal degeneration and neurological disabilities. Remyelination is a regenerative process that replaces lost myelin. However, remyelination is disrupted in demyelinating diseases such as multiple sclerosis, at least partially, due to the failu...
