Neuron 2024:S0896-6273(24)00576-2.

Abstract
Tau interacts with α-Synuclein (α-Syn) and co-localizes with it in the Lewy bodies, influencing α-Syn pathology in Parkinson's disease (PD). However, whether these biochemical events regulate α-Syn pathology spreading from the gut into the brain remains incompletely understood. Here, we show that α-Syn and Tau co-pathology is spread into the brain in gut-inducible SYN103+/- and/or TAU368+/- transgenic mouse models, eliciting behavioral defects. Gut pathology was initially observed, and α-Syn or Tau pathology was subsequently propagated into the DMV or NTS and then to other brain regions. Remarkably, more extensive spreading and widespread neuronal loss were found in double transgenic mice (Both) than in single transgenic mice. Truncal vagotomy and α-Syn deficiency significantly inhibited synucleinopathy or tauopathy spreading. The α-Syn PET tracer [18F]-F0502B detected α-Syn aggregates in the gut and brain. Thus, α-Syn and Tau co-pathology can propagate from the gut to the brain, triggering behavioral disorders.

Abstract
Cell therapy for the treatment of demyelinating diseases such as multiple sclerosis is hampered by poor survival of donor oligodendrocyte cell preparations, resulting in limited therapeutic outcomes. Excessive cell death leads to the release of intracellular alloantigens, which likely exacerbate local inflammation and may predispose the graft to eventual rejection. Here, we engineered innovative cell-instructive shear-thinning hydrogels (STHs) with tunable viscoelasticity and bioactivity for minimally invasive delivery of primary human oligodendrocyte progenitor cells (hOPCs) to the brain of a shiverer/rag2 mouse, a model of congenital hypomyelinating disease. The STHs enabled immobilization of prosurvival signals, including a recombinantly designed bidomain peptide and platelet-derived growth factor. Notably, STHs reduced the death rate of hOPCs significantly, promoted the production of myelinating oligodendrocytes, and enhanced myelination of the mouse brain 12 weeks post-implantation. Our results demonstrate the potential of STHs loaded with biological cues to improve cell therapies for the treatment of devastating myelopathies.

Abstract
Myelin, the insulating sheath that surrounds neuronal axons, is produced by oligodendrocytes in the central nervous system (CNS). This evolutionary innovation, which first appears in jawed vertebrates, enabled rapid transmission of nerve impulses, more complex brains, and greater morphological diversity. Here, we report that RNA-level expression of RNLTR12-int, a retrotransposon of retroviral origin, is essential for myelination. We show that RNLTR12-int-encoded RNA binds to the transcription factor SOX10 to regulate transcription of myelin basic protein (Mbp, the major constituent of myelin) in rodents. RNLTR12-int-like sequences (which we name RetroMyelin) are found in all jawed vertebrates, and we further demonstrate their function in regulating myelination in two different vertebrate classes (zebrafish and frogs). Our study therefore suggests that retroviral endogenization played a prominent role in the emergence of vertebrate myelin.

Oscillatory calcium release and sustained store-operated oscillatory calcium signaling prevents differentiation of human oligodendrocyte progenitor cells. Sci Rep 2022; 12:6160.

Abstract
Endogenous remyelination in demyelinating diseases such as multiple sclerosis is contingent upon the successful differentiation of oligodendrocyte progenitor cells (OPCs). Signaling via the Gαq-coupled muscarinic receptor (M1/3R) inhibits human OPC differentiation and impairs endogenous remyelination in experimental models. We hypothesized that calcium release following Gαq-coupled receptor (GqR) activation directly regulates human OPC (hOPC) cell fate. In this study, we show that specific GqR agonists activating muscarinic and metabotropic glutamate receptors induce characteristic oscillatory calcium release in hOPCs and that these agonists similarly block hOPC maturation in vitro. Both agonists induce calcium release from endoplasmic reticulum (ER) stores and store operated calcium entry (SOCE) likely via STIM/ORAI-based channels. siRNA mediated knockdown (KD) of obligate calcium sensors STIM1 and STIM2 decreased the magnitude of muscarinic agonist induced oscillatory calcium release and attenuated SOCE in hOPCs. In addition, STIM2 expression was necessary to maintain the frequency of calcium oscillations and STIM2 KD reduced spontaneous OPC differentiation. Furthermore, STIM2 siRNA prevented the effects of muscarinic agonist treatment on OPC differentiation suggesting that SOCE is necessary for the anti-differentiative action of muscarinic receptor-dependent signaling. Finally, using a gain-of-function approach with an optogenetic STIM lentivirus, we demonstrate that independent activation of SOCE was sufficient to significantly block hOPC differentiation and this occurred in a frequency dependent manner while increasing hOPC proliferation. These findings suggest that intracellular calcium oscillations directly regulate hOPC fate and that modulation of calcium oscillation frequency may overcome inhibitory Gαq-coupled signaling that impairs myelin repair.

Abstract
Oligodendrocytes are multifunctional central nervous system (CNS) glia that are essential for neural function in gnathostomes. The evolutionary origins and specializations of the oligodendrocyte cell type are among the many remaining mysteries in glial biology and neuroscience. The role of oligodendrocytes as CNS myelinating glia is well established, but recent studies demonstrate that oligodendrocytes also participate in several myelin-independent aspects of CNS development, function, and maintenance. Furthermore, many recent studies have collectively advanced our understanding of myelin plasticity, and it is now clear that experience-dependent adaptations to myelination are an additional form of neural plasticity. These observations beg the questions of when and for which functions the ancestral oligodendrocyte cell type emerged, when primitive oligodendrocytes evolved new functionalities, and the genetic changes responsible for these evolutionary innovations. Here, I review recent findings and propose working models addressing the origins and evolution of the oligodendrocyte cell type and adaptive myelination. The core gene regulatory network (GRN) specifying the oligodendrocyte cell type is also reviewed as a means to probe the existence of oligodendrocytes in basal vertebrates and chordate invertebrates.

Overcoming the inhibitory microenvironment surrounding oligodendrocyte progenitor cells following experimental demyelination. Nat Commun 2021; 12:1923.

Abstract
Chronic demyelination in the human CNS is characterized by an inhibitory microenvironment that impairs recruitment and differentiation of oligodendrocyte progenitor cells (OPCs) leading to failed remyelination and axonal atrophy. By network-based transcriptomics, we identified sulfatase 2 (Sulf2) mRNA in activated human primary OPCs. Sulf2, an extracellular endosulfatase, modulates the signaling microenvironment by editing the pattern of sulfation on heparan sulfate proteoglycans. We found that Sulf2 was increased in demyelinating lesions in multiple sclerosis and was actively secreted by human OPCs. In experimental demyelination, elevated OPC Sulf1/2 expression directly impaired progenitor recruitment and subsequent generation of oligodendrocytes thereby limiting remyelination. Sulf1/2 potentiates the inhibitory microenvironment by promoting BMP and WNT signaling in OPCs. Importantly, pharmacological sulfatase inhibition using PI-88 accelerated oligodendrocyte recruitment and remyelination by blocking OPC-expressed sulfatases. Our findings define an important inhibitory role of Sulf1/2 and highlight the potential for modulation of the heparanome in the treatment of chronic demyelinating disease. Demyelination results in impairments in oligodendrocyte progenitor cell recruitment. Here the authors identify sulfatase 1/2 as a potential modulator of myelination by modulating the microenvironment around oligodendrocyte progenitor cells.

Abstract
Remyelination requires the generation of new oligodendrocytes (OLs), which are derived from oligodendrocyte progenitor cells (OPCs). Maturation of OPCs into OLs is a multi-step process. Here, we describe a microRNA expressed by OLs, miR-27a, as a regulator of OL development and survival. Increased levels of miR-27a were found in OPCs associated with multiple sclerosis (MS) lesions and in animal models of demyelination. Increased levels of miR-27a led to inhibition of OPC proliferation by cell-cycle arrest, as well as impaired differentiation of human OPCs (hOPCs) and myelination by dysregulating the Wnt-β-catenin signaling pathway. In vivo administration of miR-27a led to suppression of myelinogenic signals, leading to loss of endogenous myelination and remyelination. Our findings provide evidence supporting a critical role for a steady-state level of OL-specific miR-27a in supporting multiple steps in the complex process of OPC maturation and remyelination.

Abstract
The maintenance of progenitor states or the differentiation of progenitors into specific lineages requires epigenetic remodeling of the gene expression program. In the central nervous system, oligodendrocyte progenitors (OPCs) give rise to oligodendrocytes (OLs), whose main function has been thought to be to produce myelin, a lipid-rich structure insulating the axons. However, recent findings suggest diverse OL transcriptional states, which might imply additional functions. The differentiation of OPCs into postmitotic OLs is a highly regulated and sensitive process and requires temporal waves of gene expression through epigenetic remodeling of the genome. In this review, we will discuss recent advances in understanding the events shaping the chromatin landscape through histone modifications and long noncoding RNAs during OPC differentiation, in physiological and pathological conditions. We suggest that epigenetic regulation plays a fundamental role in governing the accessibility of transcriptional machinery to DNA sequences, which ultimately determines functional outcomes in OLs.

Abstract
Human oligodendrocyte progenitor cells (hOPCs) persist into adulthood as an abundant precursor population capable of division and differentiation. The transcriptional mechanisms that regulate hOPC homeostasis remain poorly defined. Herein, we identify paired related homeobox protein 1 (PRRX1) in primary PDGFαR+ hOPCs. We show that enforced PRRX1 expression results in reversible G1/0 arrest. While both PRRX1 splice variants reduce hOPC proliferation, only PRRX1a abrogates migration. hOPC engraftment into hypomyelinated shiverer/rag2 mouse brain is severely impaired by PRRX1a, characterized by reduced cell proliferation and migration. PRRX1 induces a gene expression signature characteristic of stem cell quiescence. Both IFN-γ and BMP signaling upregulate PRRX1 and induce quiescence. PRRX1 knockdown modulates IFN-γ-induced quiescence. In mouse brain, PRRX1 mRNA was detected in non-dividing OPCs and is upregulated in OPCs following demyelination. Together, these data identify PRRX1 as a regulator of quiescence in hOPCs and as a potential regulator of pathological quiescence.

Abstract
Investigating human oligodendrogenesis and the interaction of oligodendrocytes with neurons and astrocytes would accelerate our understanding of the mechanisms underlying white matter disorders. However, this is challenging due to limited accessibility of functional human brain tissue. Here, we developed a novel differentiation method of human induced pluripotent stem cells (hiPS cells) to generate three-dimensional (3D) neural spheroids that contain oligodendrocytes as well as neurons and astrocytes, called human oligodendrocyte spheroids (hOLS). We demonstrate that oligodendrocyte-lineage cells derived in hOLS transition through developmental stages similar to primary human oligodendrocytes and that the migration of oligodendrocyte-lineage cells and their susceptibility to lysolecithin exposure can be captured by live imaging. Moreover, their morphology changes as they mature over time in vitro and start myelinating neurons. We anticipate that this method can be used to study oligodendrocyte development, myelination, and interactions with other major cell types in the central nervous system.

Muscarinic Receptor M 3R Signaling Prevents Efficient Remyelination by Human and Mouse Oligodendrocyte Progenitor Cells. J Neurosci 2018; 38:6921-6932.

Abstract
Muscarinic receptor antagonists act as potent inducers of oligodendrocyte differentiation and accelerate remyelination. However, the use of muscarinic antagonists in the clinic is limited by poor understanding of the operant receptor subtype, and questions regarding possible species differences between rodents and humans. Based on high selective expression in human oligodendrocyte progenitor cells (OPCs), we hypothesized that M3R is the functionally relevant receptor. Lentiviral M3R knockdown in human primary CD140a/PDGFαR+ OPCs resulted in enhanced differentiation in vitro and substantially reduced the calcium response following muscarinic agonist treatment. Importantly, following transplantation in hypomyelinating shiverer/rag2 mice, M3R knockdown improved remyelination by human OPCs. Furthermore, conditional M3R ablation in adult NG2-expressing OPCs increased oligodendrocyte differentiation and led to improved spontaneous remyelination in mice. Together, we demonstrate that M3R receptor mediates muscarinic signaling in human OPCs that act to delay differentiation and remyelination, suggesting that M3 receptors are viable targets for human demyelinating disease.SIGNIFICANCE STATEMENT The identification of drug targets aimed at improving remyelination in patients with demyelination disease is a key step in development of effective regenerative therapies to treat diseases, such as multiple sclerosis. Muscarinic receptor antagonists have been identified as effective potentiators of remyelination, but the receptor subtypes that mediate these receptors are unclear. In this study, we show that genetic M3R ablation in both mouse and human cells results in improved remyelination and is mediated by acceleration of oligodendrocyte commitment from oligodendrocyte progenitor cells. Therefore, M3R represents an attractive target for induced remyelination in human disease.

Abstract
Scarce access to primary samples and lack of efficient protocols to generate oligodendrocytes (OLs) from human pluripotent stem cells (hPSCs) are hampering our understanding of OL biology and the development of novel therapies. Here, we demonstrate that overexpression of the transcription factor SOX10 is sufficient to generate surface antigen O4-positive (O4+) and myelin basic protein-positive OLs from hPSCs in only 22 days, including from patients with multiple sclerosis or amyotrophic lateral sclerosis. The SOX10-induced O4+ population resembles primary human OLs at the transcriptome level and can myelinate neurons in vivo. Using in vitro OL-neuron co-cultures, myelination of neurons by OLs can also be demonstrated, which can be adapted to a high-throughput screening format to test the response of pro-myelinating drugs. In conclusion, we provide an approach to generate OLs in a very rapid and efficient manner, which can be used for disease modeling, drug discovery efforts, and potentially for therapeutic OL transplantation. SOX10 is sufficient to generate myelinating human OLs from hPSCs in only 22 days SOX10-induced OLs resemble primary human OLs at the transcriptome level The methodology allows efficient generation of OLs from MS and ALS patients OL-neuron co-cultures respond to myelinating drugs in a high-throughput setting

Abstract
Oligodendrocyte development has been studied for several decades, and has served as a model system for both neurodevelopmental and stem/progenitor cell biology. Until recently, the vast majority of studies have been conducted in lower species, especially those focused on rodent development and remyelination. In humans, the process of myelination requires the generation of vastly more myelinating glia, occurring over a period of years rather than weeks. Furthermore, as evidenced by the presence of chronic demyelination in a variety of human neurologic diseases, it appears likely that the mechanisms that regulate development and become dysfunctional in disease may be, in key ways, divergent across species. Improvements in isolation techniques, applied to primary human neural and oligodendrocyte progenitors from both fetal and adult brain, as well as advancements in the derivation of defined progenitors from human pluripotent stem cells, have begun to reveal the extent of both species-conserved signaling pathways and potential key differences at cellular and molecular levels. In this article, we will review the commonalities and differences in myelin development between rodents and man, describing the approaches used to study human oligodendrocyte differentiation and myelination, as well as heterogeneity within targetable progenitor pools, and discuss the advances made in determining which conserved pathways may be both modeled in rodents and translate into viable therapeutic strategies to promote myelin repair.

Abstract
The mammalian central nervous system (CNS) is unable to regenerate. In contrast, the CNS of fish, including the visual system, is able to regenerate after damage. Moreover, the fish visual system grows continuously throughout the life of the animal, and it is therefore an excellent model to analyze processes of myelination and re-myelination after an injury. Here we analyze Sox10+ oligodendrocytes in the goldfish retina and optic nerve in controls and after two kinds of injuries: cryolesion of the peripheral growing zone and crushing of the optic nerve. We also analyze changes in a major component of myelin, myelin basic protein (MBP), as a marker for myelinated axons. Our results show that Sox10+ oligodendrocytes are located in the retinal nerve fiber layer and along the whole length of the optic nerve. MBP was found to occupy a similar location, although its loose appearance in the retina differed from the highly organized MBP+ axon bundles in the optic nerve. After optic nerve crushing, the number of Sox10+ cells decreased in the crushed area and in the optic nerve head. Consistent with this, myelination was highly reduced in both areas. In contrast, after cryolesion we did not find changes in the Sox10+ population, although we did detect some MBP- degenerating areas. We show that these modifications in Sox10+ oligodendrocytes are consistent with their role in oligodendrocyte identity, maintenance and survival, and we propose the optic nerve head as an excellent area for research aimed at better understanding of de- and remyelination processes.

Abstract
Human oligodendrocyte progenitor cell (OPC) specification and differentiation occurs slowly and limits the potential for cell-based treatment of demyelinating disease. In this study, using FACS-based isolation and microarray analysis, we identified a set of transcription factors expressed by human primary CD140a(+)O4(+) OPCs relative to CD133(+)CD140a(-) neural stem/progenitor cells (NPCs). Among these, lentiviral overexpression of transcription factors ASCL1, SOX10, and NKX2.2 in NPCs was sufficient to induce Sox10 enhancer activity, OPC mRNA, and protein expression consistent with OPC fate; however, unlike ASCL1 and NKX2.2, only the transcriptome of SOX10-infected NPCs was induced to a human OPC gene expression signature. Furthermore, only SOX10 promoted oligodendrocyte commitment, and did so at quantitatively equivalent levels to native OPCs. In xenografts of shiverer/rag2 animals, SOX10 increased the rate of mature oligodendrocyte differentiation and axon ensheathment. Thus, SOX10 appears to be the principle and rate-limiting regulator of myelinogenic fate from human NPCs.

Abstract
The mechanisms underlying the specification of oligodendrocyte fate from multipotent neural progenitor cells (NPCs) in developing human brain are unknown. In this study, we sought to identify antigens sufficient to distinguish NPCs free from oligodendrocyte progenitor cells (OPCs). We investigated the potential overlap of NPC and OPC antigens using multicolor fluorescence-activated cell sorting (FACS) for CD133/PROM1, A2B5, and CD140a/PDGFαR antigens. Surprisingly, we found that CD133, but not A2B5, was capable of enriching for OLIG2 expression, Sox10 enhancer activity, and oligodendrocyte potential. As a subpopulation of CD133-positive cells expressed CD140a, we asked whether CD133 enriched bone fide NPCs regardless of CD140a expression. We found that CD133(+)CD140a(-) cells were highly enriched for neurosphere initiating cells and were multipotent. Importantly, when analyzed immediately following isolation, CD133(+)CD140a(-) NPCs lacked the capacity to generate oligodendrocytes. In contrast, CD133(+)CD140a(+) cells were OLIG2-expressing OPCs capable of oligodendrocyte differentiation, but formed neurospheres with lower efficiency and were largely restricted to glial fate. Gene expression analysis further confirmed the stem cell nature of CD133(+)CD140a(-) cells. As human CD133(+) cells comprised both NPCs and OPCs, CD133 expression alone cannot be considered a specific marker of the stem cell phenotype, but rather comprises a heterogeneous mix of glial restricted as well as multipotent neural precursors. In contrast, CD133/CD140a-based FACS permits the separation of defined progenitor populations and the study of neural stem and oligodendrocyte fate specification in the human brain.
