Fingolimod does not enhance cerebellar remyelination in the cuprizone model

Fingolimod (FTY720) is approved for treatment of relapsing-remitting multiple sclerosis. In vitro studies have found that fingolimod stimulates remyelination in cerebellar slices, but in vivo animal studies have not detected any positive effect on cerebral remyelination. The discrepant findings could be a result of different mechanisms underlying cerebral and cerebellar remyelination. The cupri...

Fingolimod (FTY720) enhances remyelination following demyelination of organotypic cerebellar slices.

Remyelination, which occurs subsequent to demyelination, contributes to functional recovery and is mediated by oligodendrocyte progenitor cells (OPCs) that have differentiated into myelinating cells. Therapeutics that impact remyelination in the CNS could be critical determinants of long-term functional outcome in multiple sclerosis (MS). Fingolimod is a S1P receptor modulator in MS clinical tr...

An Alternative Cuprizone-Induced Demyelination and Remyelination Mouse Model

The cuprizone model is a well-established and investigated paradigm to study demyelination and remyelination in rodents. Cuprizone is usually administrated by mixing in the powdered or pelleted rodent chow. However, since cuprizone is sensitive to the environment and the consumption of it varies between different animals, the major issue is the discrepancy in demyelination of the animals. This ...

A New Model of Cuprizone-Mediated Demyelination/Remyelination

In the central nervous system, demyelinating diseases, such as multiple sclerosis, result in devastating long-term neurologic damage, in part because of the lack of effective remyelination in the adult human brain. One model used to understand the mechanisms regulating remyelination is cuprizone-induced demyelination, which allows investigation of remyelination mechanisms in adult animals follo...

rHIgM22 enhances remyelination in the brain of the cuprizone mouse model of demyelination

Failure of oligodendrocyte precursor cells (OPCs) to differentiate and remyelinate axons is thought to be a major cause of the limited ability of the central nervous system to repair plaques of immune-mediated demyelination in multiple sclerosis (MS). Current therapies for MS aim to lessen the immune response in order to reduce the frequency and severity of attacks, but these existing therapies...
