Selective Vulnerability of Parvocellular Oxytocin Neuron in Social Dysfunction

ABSTRACT: Despite the rapid progress in dissecting neural circuits for social behaviors, it remains unknown whether specific neural cell types are selectively vulnerable in social dysfunction cases often associated with neurodevelopmental disorders. Here, employing a single-cell transcriptome analysis in mice, we show that an embryonic disturbance known to induce social dysfunction preferentially impairs gene expressions crucial for neural functions in parvocellular oxytocin (OT) neurons—a subtype linked to social rewards—while neighboring cell types experience a lesser impact. Chemogenetic stimulation of OT neurons at the neonatal stage ameliorated social deficits, concomitant with a cell-type-specific sustained recovery of the pivotal gene expressions. Our data illuminates the transcriptomic selective vulnerability within the hypothalamic social behavioral center, offering a potential therapeutic target through specific neonatal neurostimulation.

Parallel social information processing circuits are differentially impacted in autism

Project description:Parallel processing circuits are thought to dramatically expand the network capabilities of the nervous system. Magnocellular and parvocellular oxytocin neurons have been proposed to subserve two parallel streams of social information processing, which allow a single molecule to encode a diverse array of ethologically distinct behaviors, although to date direct evidence to support this hypothesis is lacking. Here we provide the first comprehensive characterization of magnocellular and parvocellular oxytocin neurons, validated across anatomical, projection target, electrophysiological, and transcriptional criteria. We next used novel multiple feature selection tools in Fmr1 KO mice to provide direct evidence that normal functioning of the parvocellular but not magnocellular oxytocin pathway is required for autism-relevant social reward behavior. Finally, we demonstrate that autism risk genes are uniquely enriched in parvocellular oxytocin neurons. Taken together these results provide the first evidence that oxytocin pathway specific pathogenic mechanisms account for social impairments across a broad range of autism etiologies.

Selective oxytocin receptor activation prevents prefrontal circuit dysfunction and social behavioral alterations in response to chronic prefrontal cortex activation in rats

Project description:Social behavioral changes are a hallmark of several neurodevelopmental and neuropsychiatric conditions, nevertheless the underlying neural substrates of such dysfunction remain poorly understood. Building evidence points to the prefrontal cortex (PFC) as one of the key brain regions that orchestrates social behavior. We used this concept with the aim to develop a translational rat model of social-circuit dysfunction, the chronic PFC activation model (CPA). Chemogenetic designer receptor hM3Dq was used to induce chronic activation of the PFC over 10 days, and the behavioral and electrophysiological signatures of prolonged PFC hyperactivity were evaluated. To test the sensitivity of this model to pharmacological interventions on longer timescales, and validate its translational potential, the rats were treated with our novel highly selective oxytocin receptor (OXTR) agonist RO6958375, which is not activating the related vasopressin V1a receptor. CPA rats showed reduced sociability in the three-chamber sociability test, and a concomitant decrease in neuronal excitability and synaptic transmission within the PFC as measured by electrophysiological recordings in acute slice preparation. Sub-chronic treatment with a low dose of the novel OXTR agonist following CPA interferes with the emergence of PFC circuit dysfunction, abnormal social behavior and specific transcriptomic changes. These results demonstrate that sustained PFC hyperactivity modifies circuit characteristics and social behaviors in ways that can be modulated by selective OXTR activation and that this model may be used to understand the circuit recruitment of prosocial therapies in drug discovery.

Effect of CCK-8s injection (20 ug/kg BW i.p.) on mRNA translational activity in hypothalamic oxytocin neurons of mice fed standard chow or high-fat/high-sugar diet (RiboTag;TRAP)

Project description:Oxytocin-expressing paraventricular hypothalamic neurons (PVN^OT neurons) integrate afferent signals from the gut including cholecystokinin (CCK) to adjust whole-body energy homeostasis. However, the molecular underpinnings by which PVN^OT neurons orchestrate gut-to-brain feeding control remain unclear. Here, we show that mice undergoing selective ablation of PVNOT neurons fail to reduce food intake in response to CCK and develop hyperphagic obesity on chow diet. Notably, exposing wildtype mice to a high-fat/high-sugar (HFHS) diet recapitulates this insensitivity towards CCK, which is linked to diet-induced transcriptional and electrophysiological aberrations specifically in PVNOT neurons. Restoring OT pathways in DIO mice via chemogenetics or polypharmacology sufficiently re-establishes CCK?s anorexigenic effects. Lastly, by single-cell profiling, we identify a specialized PVN^OT neuronal subpopulation with increased ?-opioid signaling under HFHS diet, which restrains their CCK-evoked activation. In sum, we here document a novel (patho)mechanism by which PVN^OT signaling uncouples a gut-brain satiation pathway under obesogenic conditions.

Functional Involvement of Septal miR-132 in Extinction and Oxytocin-mediated Reversal of Social Fear

Project description:Social interactions are critical components for the survival of mammalian biology and evolution. Dysregulation of social behavior often leads to psychopathologies such as social anxiety disorder, which is characterized by an intense fear and avoidance of social situations. Using the social fear conditioning (SFC) paradigm, we analyzed expression levels of miR-132-3p and miR-124-3p within the septum, a brain region essential for social behavior and fear, after acquisition and extinction of social fear. Functional in vivo approaches using pharmacology, functional inhibition of miR-132-3p, viral miR-132 overexpression and shRNA-mediated knockdown of miR-132-3p within oxytocin receptor positive neurons confirmed septal miR-132-3p to be involved in social fear extinction and the oxytocin-mediated reversal of social fear. Moreover, Argonaute-RNA-co-immunoprecipitation-microarray analysis and further target mRNA quantification, depicted growth differentiation factor-5 (GDF-5) to be involved in miR-132-3p-mediated regulation of social fear extinction. Local application of GDF-5 resulted in impaired social fear extinction, an effect which seems to be mediated by miR-132-3p. In summary, we show that septal miR-132-3p is functionally involved in social fear extinction learning and oxytocin-mediated reversal of social fear.

Single-cell transcriptome analysis of secretagogin mRNA expressing cells from the mouse hypothalamic paraventricular nucleus

Project description:The molecular mechanism regulating phasic corticotropin-releasing hormone (CRH) release from parvocellular neurons (PVN) remains poorly understood. Here, we find a cohort of parvocellular cells interspersed with magnocellular PVN neurons expressing secretagogin. Single-cell transcriptome analysis combined with protein interactome profiling identifies secretagogin neurons as a distinct CRH-releasing neuron population reliant on secretagogin’s Ca2+ sensor properties and protein interactions with the vesicular traffic and exocytosis release machineries to liberate this key hypothalamic releasing hormone.

Rescue of oxytocin response and social behavior in a rodent model of autism

Project description:One of the most fundamental challenges in developing treatments for autism-spectrum disorders is the heterogeneity of the condition. More than one hundred genetic mutations confer high risk for autism, with each individual mutation accounting for only a small fraction of autism cases. Subsets of risk genes can be grouped into functionally-related pathways, most prominently synaptic proteins, translational regulation, and chromatin modifications. To possibly circumvent this genetic complexity, recent therapeutic strategies have focused on the neuropeptides oxytocin and vasopressin which regulate aspects of social behavior in mammals. However, whether genetic risk factors might predispose to autism due to modification of oxytocinergic signaling remains largely unknown. Here, we report that an autism-associated mutation in the synaptic adhesion molecule neuroligin-3 (Nlgn3) results in impaired oxytocin signaling in dopaminergic neurons and in altered social novelty responses in mice. Surprisingly, loss of Nlgn3 is accompanied by a disruption of translation homeostasis in the ventral tegmental area. Treatment of Nlgn3KO mice with a novel, highly specific, brain-penetrant inhibitor of MAP-kinase interacting kinases resets mRNA translation and restores oxytocin and social novelty responses. Thus, this work identifies an unexpected convergence between the genetic autism risk factor Nlgn3, translational regulation, and oxytocinergic signaling. Focus on such common core plasticity elements might provide a pragmatic approach to reduce the heterogeneity of autism phenotypes. Ultimately, this would allow for mechanism-based stratification of patient populations to increase the success of therapeutic interventions.

Basal amygdala-nucleus accumbens glutamate neurons respond to either social reward or social aversion

Project description:A substantial proportion of basal amygdala (BA) glutamate neurons project to nucleus accumbens (NAc). The evidence that these neurons are activated by reward and/or aversion is equivocal. Social stimuli are highly salient, and in male mice we conducted a detailed analysis of the responsiveness of BA-NAc neurons to estrous female (social reward, SR) or aggressive male (social aversion, SA). Both SR and SA activated c-Fos expression in a relatively high number of BA-NAc neurons in intermediate (int) BA. Using Fos-TRAP2 mice, the majority of social int-BA-NAc neurons were activated by either SR or SA, i.e. were monovalent, and in similar numbers. Fiber photometry provided corroborative evidence that int-BA-NAc neural pathway activity was similar in response to SR or SA. These findings contribute substantially to understanding the topography and valence-specificity of BA-NAc neurons with respect to highly salient stimuli, and to identifying molecular targets for treatment of reward- or aversion-specific psychopathologies.

An amygdala circuit that supresses social engagement

Project description:Innate social behaviors, such as mating and fighting, are fundamental to animal reproduction and survival. However, social engagements are associated with risks for the individual, such as pathogenic infection and physical injury. Little is known about the neural mechanism that allows for appropriate risk assessment and the suppression of hazardous social interactions. We have identified the posteromedial nucleus of the cortical amygdala (COApm) as a locus required for the suppression of mating with an unhealthy female and aggressive behaviors towards a dominant male intruder. Using anatomical tracing, functional imaging, and circuit-level epistatic analyses, we show that suppression of social engagements is mediated by the COApm projections onto the glutamatergic population of the medial amygdalar nucleus (MEA). We further show that this projection that governs social engagements is demarcated by expression of both the neuromodulator thyrotropin-releasing hormone (TRH) in the COApm and the TRH-receptor (TRHR) in the postsynaptic MEA glutamatergic neurons. Modulating TRH-expressing neurons as well as infusing TRHR ligand into the MEA phenocopy functional manipulation of the COApm-MEA circuit. We have, therefore, uncovered a novel neural mechanism that endows animals with the ability to modulate innate reproductive and aggressive social interactions according to the health and threat status of reciprocating individuals. Deficits in such a mechanism may lead to the spread of disease, while uncontrolled engagement may lead to pathological conditions, such as social withdrawal and depression.
