Abstract
Myelination is the terminal step in a complex and precisely timed program that orchestrates the proliferation, migration and differentiation of oligodendroglial cells. It is thought that Sonic Hedgehog (Shh) acting on Smoothened (Smo) participates in regulating this process, but that these effects are highly context dependent. Here, we investigate oligodendroglial development and remyelination from three specific transgenic lines: NG2-CreERT2 (control), Smofl/fl/NG2-CreERT2 (loss of function), and SmoM2/NG2-CreERT2 (gain of function), as well as pharmacological manipulation that enhance or inhibit the Smo pathway (Smoothened Agonist (SAG) or cyclopamine treatment, respectively). To explore the effects of Shh/Smo on differentiation and myelination in vivo, we developed a highly quantifiable model by transplanting oligodendrocyte precursor cells (OPCs) in the retina. We find that myelination is greatly enhanced upon cyclopamine treatment and hypothesize that Shh/Smo could promote OPC proliferation to subsequently inhibit differentiation. Consistent with this hypothesis, we find that the genetic activation of Smo significantly increased numbers of OPCs and decreased oligodendrocyte differentiation when we examined the corpus callosum during development and after cuprizone demyelination and remyelination. However, upon loss of function with the conditional ablation of Smo, myelination in the same scenarios are unchanged. Taken together, our present findings suggest that the Shh pathway is sufficient to maintain OPCs in an undifferentiated state, but is not necessary for myelination and remyelination.

Abstract
Motor neurons (MNs) and oligodendrocyte precursor cells (OPCs) emerge sequentially from the pMN precursor domain during spinal cord development. MNs diversify into muscle specific subtypes and settle in stereotypic locations in the ventral horns. In contrast, OPCs are mobile and appear to evenly populate the parenchyma. Whether earlier born MNs influence OPC production is controversial. We found that Sonic Hedgehog signaling emanating from nascent MNs of the lateral motor column is critical for maintaining a larger and more yielding pMN domain at limb levels compared to trunk levels during OPC production. Reduced Shh signaling resulted in unrecoverable diminishment of pMN domain based OPC production leaving the spinal cord impoverished of OPC. Our results suggest that production of OPC at limb levels is contingent on completion of MN production.

Abstract
Remyelination after white matter injury (WMI) often fails in diseases such as multiple sclerosis because of improper recruitment and repopulation of oligodendrocyte precursor cells (OPCs) in lesions. How OPCs elicit specific intracellular programs in response to a chemically and mechanically diverse environment to properly regenerate myelin remains unclear. OPCs construct primary cilia, specialized signaling compartments that transduce Hedgehog (Hh) and G-protein-coupled receptor (GPCR) signals. We investigated the role of primary cilia in the OPC response to WMI. Removing cilia from OPCs genetically via deletion of Ift88 results in OPCs failing to repopulate WMI lesions because of reduced proliferation. Interestingly, loss of cilia does not affect Hh signaling in OPCs or their responsiveness to Hh signals but instead leads to dysfunctional cyclic AMP (cAMP)-dependent cAMP response element-binding protein (CREB)-mediated transcription. Because inhibition of CREB activity in OPCs reduces proliferation, we propose that a GPCR/cAMP/CREB signaling axis initiated at OPC cilia orchestrates OPC proliferation during development and in response to WMI.

Abstract
Oligodendrocytes generate myelin sheaths vital for the formation, health, and function of the central nervous system. Mounting evidence suggests that receptor tyrosine kinases (RTKs) are crucial for oligodendrocyte differentiation and myelination in the CNS. It was recently reported that discoidin domain receptor 1 (Ddr1), a collagen-activated RTK, is expressed in oligodendrocyte lineage. However, its specific expression stage and functional role in oligodendrocyte development in the CNS remain to be determined. In this study, we report that Ddr1 is selectively upregulated in newly differentiated oligodendrocytes in the early postnatal CNS and regulates oligodendrocyte differentiation and myelination. Ddr1 knock-out mice of both sexes displayed compromised axonal myelination and apparent motor dysfunction. Ddr1 deficiency alerted the ERK pathway, but not the AKT pathway in the CNS. In addition, Ddr1 function is important for myelin repair after lysolecithin-induced demyelination. Taken together, the current study described, for the first time, the role of Ddr1 in myelin development and repair in the CNS, providing a novel molecule target for the treatment of demyelinating diseases.

Abstract
Remyelination is a fundamental repair process in the central nervous system (CNS) that is triggered by demyelinating events. In demyelinating diseases, oligodendrocytes (OLs) are targeted, leading to myelin loss, axonal damage, and severe functional impairment. While spontaneous remyelination often fails in the progression of demyelinating diseases, increased understanding of the mechanisms and identification of targets that regulate myelin regeneration becomes crucial. To date, several signaling pathways have been implicated in the remyelination process, including the Hedgehog (Hh) signaling pathway. This review summarizes the current data concerning the complicated roles of the Hh signaling pathway in the context of remyelination. We will highlight the open issues that have to be clarified prior to bringing molecules targeting the Hh signaling to demyelinating therapy.

Abstract
Myelin sheathes ensure the rapid conduction of neural impulse and provide nutritional support for neurons. Myelin sheathes are formed by differentiated oligodendrocytes (OLs) in the central nervous system. During OL development, the differentiation of oligodendrocyte progenitor cells (OPCs) into mature OLs is controlled by both positive differentiation factors (drivers) and negative regulatory factors (brakes). Previous studies have suggested Id2 and Id4 as the key negative factors for OL differentiation. However, these conclusions were mainly based on in vitro studies and the reported OL phenotype in Id4 mutants appear to be mild. In this study, we systematically investigated the in vivo function of Id2 and Id4 genes in OL differentiation in their genetic mutants and in embryonic chicken spinal cord. Our results showed that disruption of Id4 has no effect on OL differentiation and maturation, whereas Id2 mutants and Id2/Id4 compound mutants display a mild and transient precocity of OL differentiation. In agreement with these loss-of-function studies, Id2, but not Id4, is weakly expressed in OPCs. Despite their minor roles in OL differentiation, forced expression of Id2 and Id4 in embryonic chicken spinal cords strongly inhibit the differentiation of OPCs. Taken together, our detailed functional and expressional studies strongly suggest that Id2 and Id4 are not the major in vivo repressors of OPC differentiation during animal development, shedding new light on the molecular regulation of early OL development.

Abstract
The G protein-coupled receptor-17 (GPR17) plays an important role in regulating the differentiation of oligodendrocytes and remyelination, which is a key negative regulator of oligodendrocyte differentiation. The present study aimed to investigate the function of GPR17 in the white matter of periventricular leukomalacia (PVL) neonatal rats. The PVL model was established in 2-day old neonatal rats by intracerebral injection of LPS (1 mg/kg). Compared to sham, GPR17 was significantly upregulated, while Olig1 was significantly downregulated in the PVL group at 1 d, 3 days, and 7 days post-modeling. Compared to the negative control (NC) group, the expression of GPR17 was suppressed, while that of Olig1 was elevated in the siRNA-GPR17 group as time progressed; the opposite results were observed in the GPR17-overexpressed group. Decreased formation of myelin sheaths as well as poor structure and loose arrangement were observed in the PVL group. Similar observations were found in the PVL + siRNA-GPR17 group at 1 d and 3 days post-modeling. However, on day 7 post-modeling, a dramatic increase in the formation of myelin sheath as well as thicker myelin sheaths were observed in the PVL + siRNA-GPR17 group. The migration ability of oligodendrocyte progenitor cells (OPCs) isolated from animals was found to be significantly suppressed in the GPR17-overexpressed group, accompanied by the downregulation of Olig1. Taken together, the regeneration and repair of myelin sheaths post-PVL white matter injury were induced by downregulating the GPR17 gene, which elevated the expression of Olig1.

Abstract
In the developing spinal cord, the majority of oligodendrocyte progenitor cells (OPCs) are induced in the ventral neuroepithelium under the control of the Sonic Hedgehog (Shh) signaling pathway, whereas a small subset of OPCs are generated from the dorsal neuroepithelial cells independent of the Shh pathway. Although dorsally-derived OPCs (dOPCs) have been shown to participate in local axonal myelination in the dorsolateral regions during development, it is not known whether they are capable of migrating into the ventral region and myelinating ventral axons. In this study, we confirmed and extended the previous study on the developmental potential of dOPCs in the absence of ventrally-derived OPCs (vOPCs). In Nestin-Smo conditional knockout (cKO) mice, when ventral oligodendrogenesis was blocked, dOPCs were found to undergo rapid amplification, spread to ventral spinal tissue, and eventually differentiated into myelinating OLs in the ventral white matter with a temporal delay, providing genetic evidence that dOPCs are capable of myelinating ventral axons in the mouse spinal cord.
