The impact of influenza pulmonary infection and inflammation on vagal bronchopulmonary sensory neurons

Project description:Influenza A virus (IAV) is rapidly detected in the airways by the immune system, with resident parenchymal cells and leukocytes orchestrating viral sensing and the induction of antiviral inflammatory responses. The airways are innervated by heterogenous populations of vagal sensory neurons which also play an important role in pulmonary defense. How these neurons respond to IAV respiratory infection remains unclear. Here, we use a murine model to provide the first evidence that vagal sensory neurons undergo significant transcriptional changes following a respiratory IAV infection. RNA sequencing on vagal sensory ganglia showed that IAV infection induced the expression of many genes associated with an antiviral and pro-inflammatory response

Transcriptional profiling of individual airway projecting vagal sensory neurons

Project description:Mammalian airways and lungs are richly innervated by bronchopulmonary sensory neurons, the vast majority of which are derived from the vagal sensory ganglia. In the present study we set out to perform high coverage single cell RNA sequencing on a population of identified murine bronchopulmonary sensory neurons collected from the vagal sensory ganglia to better define the molecular expression profiles of these cell types. Given the importance of P2X2 in differentiating nodose from jugular sensory neurons, we further aimed to investigate the relationship between transcriptional expression of identified genes and P2X2 expression.

An atlas of vagal sensory neurons and their molecular specialization

Project description:Sensory functions of the vagus nerve are critical for specific aware perceptions and for monitoring visceral functions in the cardio-pulmonary and gastrointestinal systems. Here we present a comprehensive identification, classification, and validation of the neuron types in the neural crest (jugular) and placode (nodose) derived vagal ganglia by single cell transcriptomic (scRNA-seq) analysis. Our results reveal major differences between neurons derived from different embryonic origins. Jugular neurons exhibit fundamental similarities to the somatosensory spinal neurons, including major types such as C-low threshold mechanoreceptors (C-LTMRs), A-LTMRs, Aδ-nociceptors, cold-, and mechano-heat C-nociceptors. In contrast, the nodose ganglion contains 18 distinct types dedicated to surveying the physiological state of the internal body. Our results reveal a vast diversity of vagal neuron types including many previously unanticipated types as well as proposed types that are consistent with chemoreceptors, nutrient detectors, baroreceptors, and stretch and volume mechanoreceptors of the respiratory, gastrointestinal, and cardiovascular systems.

Vagal Sensory Neuron-Derived FGF3 Regulates Insulin Secretion and Energy Balance

Project description:The vagus nerve has long been associated with the regulation of energy balance. However, the identity of the molecules mediating these effects remain largely unknown. Here, we used RNA sequencing to interrogate the molecular repertoire of the mouse vagal afferents. We found that Fgf3 mRNA is upregulated in the jugular-nodose ganglia under acute insulin resistance. Together, we provide evidence for efferent-like roles of the vagal afferents and identify Fgf3 as a novel vagal sensory-derived metabolic hormone that regulates insulin secretion and energy expenditure.

Genetic identification of vagal sensory neurons that control feeding

Project description:Energy homeostasis requires precise measurement of the quantity and quality of ingested food. The vagus nerve innervates the gut and can detect diverse interoceptive cues, but the identity of the key sensory neurons and corresponding signals that regulate food intake remains unknown. Here we use an approach for target-specific, single-cell RNA sequencing to generate a map of the vagal cell types that innervate the gastrointestinal tract. We show that unique molecular markers identify vagal neurons with distinct innervation patterns, sensory endings, and function. Surprisingly, we find that food intake is most sensitive to stimulation of mechanoreceptors in the intestine, whereas nutrient-activated mucosal afferents have no effect. Peripheral manipulations combined with central recordings reveal that intestinal mechanoreceptors, but not other cell types, potently and durably inhibit hunger-promoting AgRP neurons in the hypothalamus. These findings identify a key role for intestinal mechanoreceptors in the regulation of feeding.

An airway protection program revealed by sweeping genetic control of vagal afferents

Project description:Sensory neurons evoke a suite of defensive reflexes to ensure airway integrity. Dysfunction of laryngeal neurons is life-threatening, causing pulmonary aspiration, dysphagia, and choking, yet relevant sensory pathways remain poorly understood. Here, we discover rare throat-innervating neurons (~100 neurons/mouse) that guard the airways against assault. We used genetic tools that broadly cover a vagal/glossopharyngeal sensory neuron atlas to map, ablate, and control specific afferent populations. Optogenetic activation of vagal P2RY1 neurons evokes a coordinated airway defense program- apnea, vocal fold adduction, swallowing, and expiratory reflexes. Selective ablation of vagal P2RY1 neurons eliminates protective responses to laryngeal water and acid challenge. Anatomical mapping revealed numerous terminal morphologies in the larynx, with P2RY1 neurons forming corpuscular endings that appose laryngeal taste buds. Epithelial cells are primary airway sentinels that communicate with second-order P2RY1 neurons through ATP. These findings provide mechanistic insights into airway defense, and a general molecular/genetic roadmap for internal organ sensation by the vagus nerve.
