Astrocytes regulate myelin clearance through recruitment of microglia during cuprizone-induced demyelination.

Recent evidence suggests that astrocytes play an important role in regulating de- and remyelination in multiple sclerosis. The role of astrocytes is controversial, and both beneficial as well as detrimental effects are being discussed. We performed loss-of-function studies based on astrocyte depletion in a cuprizone-induced rodent model of demyelination. This led to strong astrogliosis accompan...

Myelin Protection by Ursolic Acid in Cuprizone-Induced Demyelination in Mice

Neuronal survival in multiple sclerosis (MS) and other demyelinating diseases depends on the preservation of myelin and remyelination of axons. Myelin protection is the main purpose to decrease myelin damage in the central nervous system (CNS). Ursolic acid (UA) as a natural product in apple is suggested to protect neural cells. This study is the first to demonstrate an effect for UA on CNS mye...

Microglia: Senescence Impairs Clearance of Myelin Debris

Growing evidence highlights the crucial physiological functions of microglia that rely on their phagocytic activities, which can be compromised with age. A new study reports the impaired clearance of myelin debris by microglia in the brain, leading to insoluble lysosomal inclusions and contributing to the immune dysfunction and senescence of these cells.

FGF2 and FGFR1 signaling regulate functional recovery following cuprizone demyelination

In demyelinating diseases, such as multiple sclerosis, remyelination offers the potential to recover function of viable denuded axons by restoring saltatory conduction and/or protecting from further damage. Mice with genetic reduction of fibroblast growth factor 2 (Fgf2) or Fgf receptor 1 (Fgfr1) exhibit dramatically improved remyelination following experimental demyelination with cuprizone. Th...
