How does Cuprizone cause demyelination?
David Perry How does Cuprizone cause demyelination?
Oral intoxication with the copper-chelator cuprizone induces oligodendrocyte apoptosis within a few days, which is closely followed by the activation of the innate immune cells in the brain, i.e., astrocytes and microglia, finally leading to demyelination of distinct white and grey matter brain areas.
What is cuprizone model?
The cuprizone mouse model is one of the most accepted model systems for the investigation of oligodendrocyte degeneration, a process critically involved in the pathogenesis of diseases such as multiple sclerosis or schizophrenia.
What is Cuprizone used for?
Cuprizone is used to produce toxic demyelination that resembles the demyelination that occurs in MS (Torkildsen et al., 2008).
What is EAE model?
Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis. This model is produced by administering a myelin basic protein peptide (MBP) fragment that induces an autoimmune response directed to the myelin sheath surrounding motor neurons.
What causes damage to myelin sheath?
Inflammation is the most common cause of myelin damage. Other causes include: certain viral infections. metabolic problems.
What causes loss of myelin sheath?
Inflammation is one common cause of damage to myelin, but other things can cause demyelination, including: viral infections. loss of oxygen. physical compression.
Is EAE similar to MS?
EAE is primarily used as an animal model of autoimmune inflammatory diseases of the CNS, and it resembles MS, the prototypical such disease, in many respects (Gold et al., 2006; Steinman and Zamvil, 2005; 2006; Farooqi et al., 2010).
Can you live without the myelin sheath?
When the myelin sheath is damaged, nerves do not conduct electrical impulses normally. Sometimes the nerve fibers are also damaged. If the sheath is able to repair and regenerate itself, normal nerve function may return. However, if the sheath is severely damaged, the underlying nerve fiber can die.
Can u reject EAE?
Applicants will receive notification of the release of the Poly EAE posting results via email. Successful applicants are to confirm the acceptance of their offers through the online portal. A non-response will be deemed as a rejection of the offer.
