Project description:Xenium platform was used for the spatial transcriptomic analysis of human DRG neurons, 100 marker genes were selected as the customized probe panel and hybridized to fresh frozen hDRG sections. Manual segmentation of each neuron soma was performed, based on expressions of pan-neuronal marker gene PGP9.5, satellite glia cell marker FAB7B, and the corresponding H.E. staining. In total, 1340 neurons were identified (excluding 75 region-of-interest with poor or unclear neuronal soma morphology in H & E staining) and clustered into 16 groups. The 16 clusters were assigned as different cell types based on marker genes expression.

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 goal of this study was to analyze global gene expression in specific populations of nociceptor sensory neurons, the neurons that detect damaging/noxious stimuli. The dorsal root ganglia (DRG), trigeminal ganglia, and nodose ganglia are anatomically distinct peripheral sensory ganglia that contain nociceptors which innervate skin, gut, lungs, and other distinct organ tissues. We used flow cytometry to purify nociceptors from these ganglia and profiled their global gene expression signatures to compare gene expression between these different anatomically distinct nociceptors. Nav1.8-Cre were bred with Rosa26-TdTomato to generate Nav1.8-Cre/R26-TdTomato reporter progeny, where all peripheral nociceptor neurons are genetically marked with red fluroescence due to specific expression of the TTX- resistant sodium channel Nav1.8. Lumbar region dorsal root ganglia (DRG), trigeminal ganglia, and nodose ganglia were dissected from mice (3 mice were pooled/sample). Highly red fluorescent neurons were Facs purified, RNA extracted, and processed for microarray analysis.

Project description:Dry skin evokes itch (pruritus), but underlying mechanisms are still elusive. To examine alterations of itch-related genes, dry skin condition was induced by AEW (Acetone/Ether/Water) treatment. In this study, RNA-seq was performed with dorsal root ganglia neurons obtained from AEW-treated ICR male mice (12-week-old) or control mice.

Project description:To investigate the effecs of commensal papillomavirus immunity on the homeostasis of highly mutated normal skin, spatial transcriptomics (Xenium, 10x Genomics, Pleasanton, CA) was performed on SKH-1 mouse back skin. The mice were treated with mouse papillomavirus (MmuPV1) or virus-like particles (VLP), followed by UV exposure for 25 weeks.

Project description:Development and plasticity in the nervous system are regulated by specific patterns of neural impulse activity. Patterned activity orchestrates spatial and temporal changes in the expression of networks of genes. These gene regulatory networks underlie the long-term changes in cell specification, growth of synaptic connections, and frequency adaptation that occur throughout neonatal and postnatal life. We show that the temporal nature of action potentials and downstream signaling differentially regulate the expression of hundreds of diverse neuronal genes through distinct gene regulatory networks. Analysis of upstream regulatory regions showed enrichment in transcription factor binding sites for NF-Kappa that was action potential firing pattern specific. Our new findings demonstrate spike-frequency decoding by action potentials at the transcriptional level by pattern-specific activation of transcription factors and associated gene-regulatory networks that operate to adjust the modalities of sensory neurons. We analyzed the transcriptomic changes in primary cultures of embronic dorsal root ganglia (DRG) neurons subjected to four electric stimulation patterns with respect to their non-stimulated counterparts. We have adopted the multiple yellow strategy in which differently fluorescent labeled biological replicas are co-hybridized with each array and then similarly labeled samples from cells subjected to different conditions are compared and results averaged over the two labels.
