Parasympathetic neurons derived from human pluripotent stem cells model human diseases and development

ABSTRACT: Parasympathetic neurons (parasymNs) belong to the autonomic nervous system (ANS) and are critical for unconscious body responses, including rest-and-digest and calming the body. ParasymN dysfunction has been found involved in neural diseases such as autonomic neuropathy and neurological autoimmune disease; and parasymN innervation is important for organ development. However, human parasymN function and dysfunction is vastly understudied, due to the lack of a model system. Human pluripotent stem cell (hPSC)-derived neurons can fill this void and serve for disease modeling, drug screening, and transplantation therapy. Here, we developed a differentiation paradigm detailing for the first time, the derivation of functional human parasymNs from Schwann cell progenitors (SCP). We employ these neurons (i) to assess human ANS development paradigms, (ii) to model neuropathy in the genetic disorder Familial Dysautonomia (FD), (iii) to show parasymN dysfunction during SARS-CoV-2 infection, (iv) to model the autoimmune disease Sjörgen’s syndrome and, (v) to show that parasymN innervation of white adipocytes during development and help mature the tissue. Our model system will become instrumental for future disease mechanistic and drug discovery studies as well as for human developmental studies.

Chronic and acute exposure to rotenone lead to distinct Parkinson’s disease-related phenotypes in human iPSC-derived peripheral neurons

Project description:Peripheral autonomic nervous system (P-ANS) dysfunction is a critical non-motor phenotype of Parkinson's disease (PD). While the majority of PD cases are sporadic with no identified PD-associated genes involved, epidemiological and animal model studies suggest an association with pesticides and other environmental toxins but underlying cellular mechanisms affecting the human P-ANS is unclear. Here, we mapped the global transcriptome changes in human induced-pluripotent stem cell (iPSC) derived P-ANS sympathetic neurons followed by exposure to the PD-related pesticide, rotenone. Surprisingly, we revealed distinct transcriptome profiles between acute and chronic exposure to rotenone. In the acute stage, there was a down regulation of specific cation channel genes mediating action potential signaling, while in the chronic stage, the human P-ANS neurons exhibited dysregulation of anti-apoptotic and Golgi apparatus-related pathways. Moreover, we identified the sodium voltage-gated channel subunit SCN3A/Nav1.3 as a potential biomarker in human P-ANS neurons associated with PD. Our analysis of the rotenone-altered coding and non-coding genome of human P-ANS neurons may thus provide insight into the pathological signaling events that occur in the sympathetic neurons during PD progression.

Serotonin signaling via 5-HT3A alters development of sacral neural crest derivatives that innervate the lower urinary tract

Project description:The autonomic nervous system is derived from the neural crest and supplies motor innervation to the smooth muscle of visceral organs, including the lower urinary tract (bladder and urethra, LUT). In rodents, autonomic innervation of the LUT is supplied by the major pelvic ganglia (PG) that lie near the neck of the bladder and proximal urethra. Compared to other autonomic ganglia, the PG are unique in that they harbor both sympathetic and parasympathetic neurons. The coordinated activity of PG neurons is critical for normal functioning of the LUT – however, surprisingly little is known about how PG neuronal diversity is established or what molecular factors control PG development. In this study we conducted transcriptome profiling of Sox10-H2BVenus+ sacral neural crest (NC) progenitors to discover candidate genes involved in PG neurogenesis.

Lrig2 is required for maturation of peripheral nerves in the urinary bladder

Project description:Leucine-rich-repeats and immunoglobulin-like-domains (LRIG2) variants can occur in urofacial syndrome (UFS), an inherited disease characterised by functional bladder outlet obstruction. We aimed to define the pathobiology underlying UFS which we hypothesised would illuminate how the bladder becomes innervated. Lrig2 was detected in pelvic ganglia supplying autonomic neurons to the bladder, and in neurites and glia emanating from explanted ganglia. One week old Lrig2 mutant mice displayed abnormally patterned bladder nerves, as did mice with mutations of Hpse2, also mutated in some UFS patients. From two weeks postnatally, Lrig2 mutants had urination defects resembling UFS. Molecules implicated in neural biology, including Nos1 which relaxes the bladder outlet, were dysregulated in newborn Lrig2 mutant bladders. These molecular aberrations preceded manifest urination defects. We discovered novel homozygous missense LRIG2 variants in non-syndromic bladder outlet obstruction. Molecules mutated in UFS are required for bladder innervation and LRIG2 variants can occur in non-syndromic bladder disease as well as in UFS.

Neural activity recorded in breast tumors originates from the sympathetic nervous

Project description:The autonomic nervous system (ANS) is a regulator of major pathological events in the tumor microenvironment (TME) of solid carcinomas where the branches of ANS have antagonistic effects on tumor growth and metastasis. Neural activity recorded from breast tumors may be associated with autonomic system function. To test this hypothesis, we performed in vivo chronic electrical recordings from murine mammary tumors of triple negative breast cancers (TNBC) following complete sub-diaphragmatic vagotomy and chemical sympathectomy. In addition to TNBC mammary tumors, we also obtained daily electrical recordings from mammary tumors overexpressing human epidermal growth factor receptor-2 (HER2) following chemical sympathectomy. Our results show that tumoral neural activity is partially blocked in vagotomized animals while it is completely absent in the sympathectomized subjects. These studies indicate that neural activity in TNBC and HER2+ tumors is predominantly generated by peripheral nor-adrenergic sympathetic nerves and provide evidence of a strong active link between the brain and tumor through the autonomic nervous system. The results implicate a new and as yet unexplored mechanism to investigate the potential role of the sympathetic nervous system in the regulation of tumor growth and metastasis.

Bioengineering of a human innervated cardiac muscle model

Project description:Cardiac autonomic neurons control cardiac contractility. Dysregulation of the autonomic nervous system can lead to sympathetic overdrive resulting in heart failure and an increased incidence of fatal arrhythmias. Here, we introduce innervated engineered human myocardium (iEHM), a novel model of neuro-cardiac junctions, constructed by fusion of a bioengineered neural organoid (BENO) patterned to autonomic nervous system and engineered human myocardium (EHM). Projections of sympathetic neurons into engineered human myocardium formed presynaptic terminals in close proximity to cardiomyocytes and an extensive vascular network co-developing in the tissues. Contractile responses to optogenetic stimulation of the accordingly engineered neuronal component demonstrated functionality of the engineered neuro-cardiac junctions in iEHM. This model will serve as a human surrogate system to delineate neuron and cardiac cell contribution to brain and heart diseases and is an important step towards engineering a human brain to heart axis in a dish.

Hippocampal CA1 Pyramidal Neurons Display Sublayer and Circuitry Dependent Degenerative Expression Profiles in Aged Female Down Syndrome Mice

Project description:People with Down syndrome (DS) have intellectual disability (ID) and develop hallmark Alzheimer’s disease (AD) pathology during midlife. There are several circuits underlying memory and executive function in the DS and AD brain that are particularly vulnerable and degenerate early in disease, most notably the septohippocampal circuit and the trisynaptic loop in the hippocampus. A fundamental lack of knowledge exists as to the etiology and mechanisms of disease progression within these critical circuits vulnerable to degeneration in DS, AD, and relevant models. This is compounded by new evidence that suggests spatial localization of neurons has profound effects on activity and innervation within the hippocampal CA1 region. We postulated gene expression changes in a DS mouse model, at a time that these circuits of input to the CA1 are degraded, would have a significant effect on gene expression in CA1 pyramidal neurons. Further, this dysfunction may be specific to spatial localization and innervation. Laser capture microscopy on pyramidal neurons from CA1 was performed, isolating the entire CA1 pyramidal neuron layer, which was compared to select populations of deep and superficial pyramidal neurons from CA1a (distal CA1, adjacent to the subiculum). RNA-seq and bioinformatic analysis was performed where profound differences in dysregulation in the DS mouse model based on their spatial location and postulated circuitry were examined.

Effects of light-at-night on the rat liver - a role for the autonomic nervous system (Experiment 1)

Project description:Exposure to light at night (LAN) has been associated with serious pathologies, including obesity, diabetes and cancer. Recently we showed that 2 hours of LAN impaired glucose tolerance in rats. Several studies have suggested that the autonomic nervous system (ANS) plays an important role in communicating these acute effects of LAN to the periphery. Here, we investigated the acute effects of LAN on the liver transcriptome of male Wistar rats. Expression levels of individual genes were not markedly affected by LAN, nevertheless pathway analysis revealed clustered changes in a number of endocrine pathways. Subsequently, we used selective hepatic denervations (sympathetic (Sx), parasympathetic (Px), total (Tx, i.e., Sx plus Px), sham) to investigate the involvement of the ANS in the effects observed. Surgical removal of the sympathetic or parasympathetic hepatic branches of the ANS resulted in many, but small changes in the liver transcriptome, including a pathway involved with circadian clock regulation, but it clearly separated the four denervation groups. On the other hand, analysis of the liver metabolome was not able to separate the denervation groups, and only 6 out of 78 metabolites were significantly up- or downregulated after denervations. Finally, removal of the sympathetic and parasympathetic hepatic nerves combined with LAN exposure clearly modulated the effects of LAN on the liver transcriptome, but left most endocrine pathways unaffected. Conclusion: One-hour light-at-night acutely affects the liver transcriptome. Part of this effect is mediated via the nervous innervation, as a hepatectomy modulated and reduced the effect of LAN on liver transcripts.

CLIPseq of hnRNP A1 from the spinal cords of mice with experimental autoimmune encephalomyelitis

Project description:Experimental autoimmune encephalomyelitis (EAE) is a mouse model for multiple sclerosis (MS) a chronic autoimmune disease of the central nervous system. We have observed dysfunction of the RNA binding protein hnRNP A1 in neurons from the brains of patients with MS, and the spinal cords of mice with EAE. Here, we sought to characterize the consequences of EAE-induced dysfunction of hnRNP A1 on the RNAs it binds by using CLIPseq to establish both the normal central nervous system RNA binding profile of hnRNP A1 in the spinal cords of naive mice, and any alterations to the binding profile of hnRNP A1 in the spinal cords of mice with EAE.
