Failure of oligodendrocyte precursor cell (OPC) differentiation contributes significantly to failed myelin sheath regeneration (remyelination) in chronic demyelinating diseases. Although the reasons for this failure are not completely understood, several lines evidence point factors present following demyelination that specifically inhibit cells capable generating remyelinating oligodendrocytes. We have previously demonstrated debris generated by inhibits remyelination inhibiting OPC and...

Failure of oligodendrocyte precursor cell (OPC) differentiation has been recognized as the leading cause for failure myelin regeneration in diseases such multiple sclerosis (MS). One explanation OPC MS is presence inhibitory molecules demyelinated lesions. So far only a few substrates have identified Semaphorin 3A (Sema3A), secreted member semaphorin family, can act repulsive guidance cue neuronal and glial cells CNS. Recent studies suggest that Sema3A also expressed active However,...

Human pluripotent stem cells (hPSCs) could provide an infinite source of clinically relevant with potential applications in regenerative medicine. However, hPSC lines vary their capacity to generate specialized cells, and the development universal protocols for production tissue-specific remains a major challenge. Here, we have addressed this limitation endodermal lineage by developing defined culture system expand differentiate human foregut (hFSCs) derived from hPSCs. hFSCs can self-renew...

Abstract Enhancing central nervous system (CNS) myelin regeneration is recognized as an important strategy to ameliorate the devastating consequences of demyelinating diseases such multiple sclerosis. Previous findings have indicated that proteins, which accumulate following demyelination, inhibit remyelination by blocking differentiation rat oligodendrocyte progenitor cells (OPCs) via modulation PKCα. We therefore screened drugs for their potential overcome this block. From our screening,...

Deletion and duplication in the human 16p11.2 chromosomal region are closely linked to neurodevelopmental disorders, specifically autism spectrum disorder. Data from neuroimaging studies suggest white matter microstructure aberrations across these conditions. In deletion carriers, potential gene dosage effects may impact organisation, contributing phenotypes including impaired cognition. However, biological mechanisms underlying this pathology remain unclear. To bridge knowledge gap, we...

The increasing effectiveness of new disease-modifying drugs that suppress disease activity in multiple sclerosis has opened up opportunities for regenerative medicines enhance remyelination and potentially slow progression. Although several targets therapeutic enhancement have emerged, few lend themselves readily to conventional drug development. Here, we used transcription profiling identify mitogen-activated protein kinase (Mapk) signalling as an important regulator involved the...

Remyelination in multiple sclerosis (MS) lesions often remains incomplete despite the presence of oligodendrocyte progenitor cells (OPCs). Amongst other factors, successful remyelination depends on phagocytic clearance myelin debris. However, proteins debris that act as potent and selective inhibitors OPC differentiation inhibit CNS remain unknown. Here, we identify transmembrane signalling protein EphrinB3 important mediator this inhibition, using a analytical approach combination with...
