Project description:This study presents the first application of comprehensive single-nuclei RNA sequencing (snRNA-seq) of dorsal root ganglion (DRG) neurons in a rat model using Parse technology. Our dataset includes two experimental models: (1) control rats representing both sexes and (2) rats with disc-associated chronic lower back pain, alongside sham-treated animals. By leveraging high-resolution transcriptomic profiling, this study provides novel insights into the molecular landscape of DRG neurons, offering a valuable resource for understanding the cellular mechanisms underlying chronic pain.

Project description:To test the potential of canonical Wnt signalling to modulate nociception via transcriptional regulation in dorsal root ganglion (DRG) neurons, we performed a genome-wide transcriptome analysis of neuron-enriched DRG cultures treated with Wnt3a or vehicle for 6 hours. Total RNA obtained from neuron-enriched mouse DRG culture subjected to Wnt3a treatment for 6 hours was compared to a matched control (vehicle-treated) DRG culture.

Project description:The dorsal root ganglion (DRG) integrates peripheral sensory signals and plays a central role in pain and neuropathy. Using single-nucleus RNA sequencing (snRNA-seq) of human DRG. We spearted 17 clusters and identified 6 major cell types, including sensory neurons and satellite glial cells (SGCs).

Project description:Preconditioning nerve injury drives pro-regenerative perineuronal macrophage activation in dorsal root ganglia (DRG). The present study reports that oncomodulin (ONCM) is produced from the regeneration-associated macrophages (RAMs) and strongly influences regeneration of DRG sensory axons. ONCM in macrophages was necessary to produce RAMs in the in vitro model of neuron-macrophage interaction and played an essential role in for preconditioning-induced neurite outgrowth. In order to gain insight on potential mechanisms downstream of ONCM for potent neurite outgrowth activity, we performed RNA-seq using cultured DRG neurons treated with ONCM.

Project description:Innate immunity is a crucial mechanism for protecting the maternal-fetal interface, whereas little is known about the placenta in chronic HIV-1 infection in mothers treated with antiretroviral therapy (ART). The maternal-fetal interface, we previously observed an enrichment of antiviral factors and inflammatory components in HIV-1 infection. TRIM family proteins are potent antagonists of viral replication; however, others can promote viral replication by ubiquitinating and degrading specific innate immune signalling proteins. We verified the expression of genes involved in innate immunity focusing on the TRIM gene profile in placental tissue (villus and decidua) from HIV-1-infected mothers. We conducted RNA sequencing of placental tissue (villus and decidua) from HIV-1 infected and control mothers. DEGs validation performed by the RT-qPCR method confirms the upregulation of TRIM21 and TRIM39 in both the decidua and the villus of HIV-1-infected samples.

Project description:Macrophages and neutrophils were sorted from the decidua and uterus of Nlrp3+/+ and Nlrp3-/- mice injected with lipopolysaccharide (LPS) or PBS and analyzed using pair-end RNA-sequencing (RNA-seq) to evaluate the effect of Nlrp3 deficiency on the transcriptomes of these innate immune cells in preterm birth.

Project description:L4-L5 segment dorsal root ganglion (DRG) samples from controls and the paclitaxel-induced peripheral neuropathy (PIPN) rats were collected at day 14 after the initiation of paclitaxel treatment. Paclitaxel and vehicle were administered intraperitoneally at 2 mg/kg for four consecutive days at a final cumulative dose of 8 mg/kg. DRG transcriptome analysis was performed by RNA sequencing using an Illumina HiSeq2500 platform.

Project description:Sensory neurons are distinguished by distinct signaling networks and receptive characteristics. Thus, sensory neuron types can be defined by linking transcriptome-based neuron typing with the sensory phenotypes. Here we classify somatosensory neurons of the mouse dorsal root ganglion (DRG) by high-coverage single-cell RNA-sequencing (10 950 ± 1 218 genes per neuron) and neuron size-based hierarchical clustering. Moreover, single DRG neurons responding to cutaneous stimuli are recorded using an in vivo whole-cell patch clamp technique and classified by neuron-type genetic markers. Small diameter DRG neurons are classified into one type of low-threshold mechanoreceptor and five types of mechanoheat nociceptors (MHNs). Each of the MHN types is further categorized into two subtypes. Large DRG neurons are categorized into four types, including neurexophilin 1-expressing MHNs and mechanical nociceptors (MNs) expressing BAI1-associated protein 2-like 1 (Baiap2l1). Mechanoreceptors expressing trafficking protein particle complex 3-like and Baiap2l1-marked MNs are subdivided into two subtypes each. These results provide a new system for cataloging somatosensory neurons and their transcriptome databases. RNA-seq of mRNA levels in 197 individual DRG neurons We performed RNA-seq on total 203 individual DRG neurons. Six of them were not qualified and thus, were excluded for further analysis. To evaluate the quality of RNA-seq, we randomly devided No.72 neurons into two parts and performed RNA-seq seperately. Thus, we had 204 individual samples from 203 individual DRG and 198 individual qualified samples from 197 individual DRG. To evaluate the homogeneity of RNA-seq data from different mice at the same age just as used, we performed RNA-seq on 5 single DRG from different mice. Here, these data from DRG were also considered as experimental control. The 'DRG_neurons_RNA_Seq.txt' contains processed data for 204 samples and 'DRG_RNA_Seq.txt' for 5 samples.
