Project description:Type 2 inflammation contributes to the pathology of airway diseases such as asthma and eosinophilic pneumonia. Yet how sensory neurons innervating the airways respond to type 2 airway inflammation is poorly understood. The goal of this study was to characterize transcriptional changes in sensory ganglia innervating the lungs in the setting of type 2 airway inflammation induced by Alternaria allergen treatment.

Project description:The vagus nerve is a key component of the parasympathetic nervous system, innervating multiple abdominal organs to monitor and regulate their function. It forms the main neural pathway between the gastrointestinal tract and the brain, playing a major role in the regulation of energy homeostasis. The cell bodies for vagal sensory neurons reside in the nodose ganglia, with the left and right ganglia reported to have distinct roles in food intake and reward. Here, we have integrated our own single nucleus RNA sequencing data with multiple publicly available datasets to create a database of 108,482 nuclei and cells, and combined this with spatial transcriptomics to present a spatio-cellular transcriptional map of the mouse nodose ganglia, the ‘NodoMap’. Nodose ganglia neuronal cells clustered into twenty-two different subtypes, all found in both left and right nodose ganglia, but with significant differences in gene expression between left and right ganglia across multiple neuronal subtypes. Overnight fasting modulated gene expression across specific neuronal subtypes, including nutrient responsive pathways. Spatial transcriptomics showed that while vagal neuronal types were highly interspersed, patterns of organisation into cellular ‘neighbourhoods’ could be observed, with neighbourhoods identified of predominantly non-neuronal cells and of different neuronal populations accompanied by glial-like cells. Thus, NodoMap provides a detailed atlas of the mouse nodose ganglia in a spatial context, providing a platform for vagovagal neurocircuit analysis, and serving as an important resource to identify targets for pharmacotherapies for metabolic disease.

Project description:Vagal afferent neurons are thought to convey primarily physiological information, whereas spinal afferents transmit noxious signals from the viscera to the central nervous system. In order to elucidate molecular identities for these different properties, we compared gene expression profiles of neurons located in nodose ganglia (NG) and dorsal root ganglia (DRG) in mice. Intraperitoneal administration of Alexa Fluor-488 conjugated Cholera toxin B allowed identification of neurons projecting to the viscera. Fluorescent neurons in DRG (from T10 to T13) and NG were isolated using laser capture microdissection. Gene expression profiles of visceral afferent neurons, obtained by microarray hybridization, were analysed using multivariate spectral map analysis, SAM algorithm (Significance Analysis of Microarray data) and fold-difference filtering. A total of 1996 genes were found to be differentially expressed in DRG versus NG, including 41 G-protein coupled receptors and 60 ion channels. Expression profiles obtained on laser-captured neurons were contrasted to those obtained on whole ganglia demonstrating striking differences and the need for microdissection when studying visceral sensory neurons because of dilution of the signal by somatic sensory neurons. Furthermore, a detailed catalogue of all adrenergic and cholinergic, GABA, glutamate, serotonin and dopamine receptors, voltage-gated potassium, sodium and calcium channels and transient receptor potential cation channels present in visceral afferents is provided. Our genome-wide expression profiling data provide novel insight into molecular signatures that underlie both functional differences and similarities between NG and DRG visceral sensory neurons. Moreover, these findings will offer novel insight into mode of action of pharmacologic agents modulating visceral sensation. Experiment Overall Design: Three separate experiments were performed. First, 5 whole dorsal root ganglia were compared to 7 whole nodose ganglia. Second, Laser captured visceral neurons derived from 5 dorsal root ganglia and 5 nodose ganglia were compared on MG-U74Av2. Third, Laser captured visceral neurons derived from 9 dorsal root ganglia and 11 nodose ganglia were compared on Mouse430_2.

Project description:The vagus nerves are important carriers of sensory information from the viscera to the brain. Emerging evidence suggests that sensory signaling through the right, but not the left, vagus nerve evokes striatal dopamine release and reinforces appetitive behaviors. However, the extent to which differential gene expression within vagal sensory neurons may underlie this asymmetric reward-related signaling is unknown. Here, we use single-nucleus RNA sequencing, in situ hybridization, and calcium imaging to identify a single cluster of neurons, defined by co-expression of Chrna3 (nicotinic acetylcholine receptor subunit 3) and Cckar (cholecystokinin 1 receptor), that is preferentially expressed in the right nodose ganglia of rats. This neuronal population also expresses several genes implicated in digestive signaling, including Glp1r and Sctr, consistent with a gut-innervating subtype. Our results suggest that right-biased expression of this unique chemosensing vagal cell type may contribute to asymmetric encoding of interoceptive rewards by the vagus nerves.

Project description:The nodose ganglia contain sensory neurons that play key roles in homeostatic behaviors and are supported by nodose glial cells. We used single cell RNA sequencing (scRNA-seq) to interrogate the molecular diversity of nodose glial cells shortly after birth.

Project description:Janus kinase 1 (JAK1) critically mediates downstream signaling from a variety of immune receptors. Gain-of-function mutations in JAK1 in humans lead to immune dysregulation and exaggerated type 2 immune responses, including atopic dermatitis. We have previously shown that JAK1 expressed in neurons mediates cytokine-enhanced itch signaling in atopic dermatitis. We generated a novel mouse expressing human JAK1 with the gain-of-function mutation p.A634D. To better understand how enhanced JAK1 signaling my impact sensory neurons, we performed single nuclei RNA sequencing on different sensory ganglia from JAK1 gain-of-function mice and littermate controls.
