Catalpol induces oligodendrocyte precursor cell-mediated remyelination in vitro.

چکیده
In demyelinating diseases such as multiple sclerosis, one of the treatment strategies includes remyelination using oligodendrocyte precursor cells (OPC). Catalpol, the extract of radix rehmanniae, is neuroprotective. Using an OPC culture model, we showed that 10 μM catalpol promotes OPC proliferation, cell migration and differentiation into mature oligodendrocytes. The 10 μM catalpol displayed stronger effects on OPCs migration and oligodendrocyte differentiation. These results suggest that catalpol has a potential role in promoting remyelination in demyelinating diseases, and is of therapeutic interest.

Lentiviral Mediated Expression of Soluble Neuropilin 1 Inhibits Semaphorin 3A-mediated Collapse Activity in Vitro
Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...

BACKGROUND Multiple sclerosis (MS) as an autoimmune disorder is a common disease occurring in central nervous system (CNS) and the remyelination plays a pivotal role in the alleviating neurological impairment in the MS. Catalpol, an effective component extracted from the Chinese herb Radix Rehmanniae, which has been proved protective in cerebral diseases. METHODS To determine the protective e...
متن کاملHistamine Receptor 3 negatively regulates oligodendrocyte differentiation and remyelination
BACKGROUND Agents promoting oligodendrocyte precursor cell differentiation have the potential to restore halted and/or delayed remyelination in patients with multiple sclerosis. However, few therapeutic targets have been identified. The objective of this study was to identify novel targets for promotion of remyelination and characterize their activity in vitro and in vivo. METHODS A high-cont...
متن کاملMyelin impairs CNS remyelination by inhibiting oligodendrocyte precursor cell differentiation.
Demyelination in the adult CNS can be followed by extensive repair. However, in multiple sclerosis, the differentiation of oligodendrocyte lineage cells present in demyelinated lesions is often inhibited by unknown factors. In this study, we test whether myelin debris, a feature of demyelinated lesions and an in vitro inhibitor of oligodendrocyte precursor differentiation, affects remyelination...
متن کاملHyaluronan blocks oligodendrocyte progenitor maturation and remyelination through TLR2.
Failure of remyelination is largely responsible for sustained neurologic symptoms in multiple sclerosis (MS). MS lesions contain hyaluronan deposits that inhibit oligodendrocyte precursor cell (OPC) maturation. However, the mechanism behind this inhibition is unclear. We report here that Toll-like receptor 2 (TLR2) is expressed by oligodendrocytes and is up-regulated in MS lesions. Pathogen-der...
