What is anti myelin oligodendrocyte glycoprotein?
MOG antibody disease (MOGAD) is a neurological, immune-mediated disorder in which there is inflammation in the optic nerve, spinal cord and/or brain. Myelin oligodendrocyte glycoprotein (MOG) is a protein that is located on the surface of myelin sheaths in the central nervous system.
What is the function of MOG?
On the basis of this knowledge we suggest three possible functions for MOG: (a) a cellular adhesive molecule, (b) a regulator of oligodendrocyte microtubule stability, and (c) a mediator of interactions between myelin and the immune system, in particular, the complement cascade.
What is MOG disease symptoms?
Signs & Symptoms
- Loss or blurring of vision in one or both eyes.
- Loss of color vision.
- Paralysis (no motor function) of a limb or limbs.
- Paraparesis (weakness) of a limb or limbs.
- Loss of sensation.
- Loss of bladder or bowel control.
- Profound bladder retention.
- Seizures. 4,9
Can MOG lead to MS?
MOG antibodies were originally thought to be involved in multiple sclerosis (MS), but subsequent studies found it to be a distinct disease. MOGAD have many similarities to neuromyelitis optica but several studies have demonstrated they have unique clinical features, treatment response, and prognosis.
Is NMO and MOG the same?
MOG-EM differs from NMOSD in further clinical characteristics e.g., in gender ratio and age at onset. In (relapsing) NMOSD, up to 90% of the patients are female, whereas the proportion of male patients in MOG-EM ranges from 43 to 63% (22, 26, 29–31, 73).
Is there a cure for MOG?
There are no FDA-approved medications for maintenance in MOG antibody disease, so anything prescribed is done off-label. The primary therapies used in the US are mycophenolate mofetil (CellCept), rituximab (Rituxan), azathioprine (Imuran), and repeated IVIG infusions or subcutaneous immunoglobulin.
Is MOG disease curable?
Many individuals with anti-MOG syndrome will recover fully after their first treatment and never relapse. However, some patients may experience recurrent attacks and need a long-term management plan. This may include IVIG and medication, such as azathioprine, myucophenolate mofetil, or rituximab.
What is myelin oligodendrocyte glycoprotein (MOG)-associated disease?
Myelin oligodendrocyte glycoprotein (MOG)-associated disease (MOGAD) is a rare, antibody-mediated inflammatory demyelinating disorder of the central nervous system (CNS) with various phenotypes starting from optic neuritis, via transverse myelitis to acute demyelinating encephalomyelitis (ADEM) and cortical encephalitis.
What is the N-terminal domain of myelin oligodendrocyte glycoprotein (MOG)?
