optic neuritis/tyrosine

The tyrosine kinase inhibitor, imatinib, used to treat certain malignancies, is in clinical trials as a potential treatment for multiple sclerosis and acute stroke. This is the first report of cases of multifocal central nervous system (CNS) demyelination following exposure to imatinib. One case was

Multiple sclerosis (MS) is a chronic, immune-mediated, demyelinating, degenerative disease of the central nervous system characterized by axonal injury and loss.¹ Approximately 77,000 Canadians aged 20 years and older live with MS and almost 75% are women.² The majority of new

Neuromyelitis optica (NMO) is characterized by concurrence of optic neuritis and transverse myelitis, which is typically associated with a spinal cord lesion extending three or more vertebral segments. NMO is an inflammatory, demyelinating central nervous system disorder, and although it has a

A 49-year-old woman diagnosed with chronic myeloid leukemia in the chronic phase was started on dasatinib treatment, after which she complained of myodesopsia. Nineteen months after diagnosis, the patient again complained of myodesopsia and developed bilateral optic neuritis. Cerebrospinal fluid

A preferential loss of retinal ganglion cells (RGCs) is observed in glaucoma and optic neuritis. Loss of tropomyosin-related kinase receptor B (TrkB)-mediated signaling has been implicated in this degeneration. Our study indicates that 7,8-dihydroxyflavone (7,8 DHF) robustly upregulates the TrkB

Retinal ganglion cells (RGCs) are the only output neurons of the vertebrate retina, integrating signals from other retinal neurons and transmitting information to the visual centers of the brain. The death of RGCs is a common outcome in many optic neuropathies, such as glaucoma, demyelinating optic
