Hypoxia can injure brain white matter tracts, comprised of axons and myelinating oligodendrocytes, leading to cerebral palsy in neonates and delayed post-hypoxic leukoencephalopathy (DPHL) in adults. In these conditions, white matter injury can be followed by myelin regeneration, but myelination often fails and is a significant contributor to fixed demyelinated lesions, with ensuing permanent n...
Demyelinating disorders of the central nervous system are among the most crippling neurological diseases affecting patients at various stages of life. In the most prominent demyelinating disease, multiple sclerosis, the regeneration of myelin sheaths often fails due to a default of the resident stem/precursor cells (oligodendrocyte precursor cells) to differentiate into mature myelin forming ce...
In demyelinating disorders such as Multiple Sclerosis (MS), targets of injury are myelin and oligodendrocytes, leading to severe neurological dysfunction. Regenerative therapies aimed at promoting oligodendrocyte maturation and remyelination are promising strategies for treatment in demyelinating disorders. Endogenous precursor cells or exogenous transplanted cells are potential sources for rem...
Cover Illustration: Confocal image of a cerebellar slice depleted its endogenous oligodendrocytes and transplanted with OPCs (oligodendrocyte precursor cells). Exogenous effectively differentiate form myelin sheaths (MBP+, rainbow pseudo-color) around Purkinje cell axons (CaBP+, grey) after 3 days co-culture. (See Bouslama-Oueghlani, L., et al, https://doi.org/10.1002/glia.24001.)
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...
The adhesion GPCR Gpr56 regulates oligodendrocyte development via interactions with Gα12/13 and RhoA
In the vertebrate central nervous system, myelinating oligodendrocytes are postmitotic and derive from proliferative oligodendrocyte precursor cells (OPCs). The molecular mechanisms that govern oligodendrocyte development are incompletely understood, but recent studies implicate the adhesion class of G protein-coupled receptors (aGPCRs) as important regulators of myelination. Here, we use zebra...
The identification of stem cells resident in the adult central nervous system has redirected the focus of research into demyelinating diseases, such as multiple sclerosis, mainly affecting the brain white matter. This immunocytochemical and morphometrical study was carried out by confocal microscopy in the adult mouse cerebral cortex, with the aim of analysing, in the brain grey matter, the cha...
