Neuromodulatory co-expression in cardiac vagal motor neurons of the Dorsal Motor Nucleus of the Vagus [RNAseq]

Project description:The activity of the cardiac vagal innervation is well known to be crucial to the maintenance of cardiac health, and to protect and recover the heart from injury. Only recently has this role been shown to depend on the activity of the underappreciated Dorsal Motor Nucleus of the Vagus (DMV). By combining neural tracing, transcriptomics, and 3D mapping in male and female Sprague Dawley rats we characterize cardiac-specific neuronal phenotypes in DMV. We find that the DMV cardiac-projecting neurons differentially express PACAP, CART, and synucleins, as well as evidence that they participate in neuromodulatory co-expression involving catecholamines. The significance of these findings is enhanced by previous knowledge of the role of PACAP at the heart and of the other neuromodulators in peripheral vagal targets.

Neuromodulatory co-expression in cardiac vagal motor neurons of the dorsal motor nucleus of the vagus.

Project description:Vagal innervation is well known to be crucial to the maintenance of cardiac health, and to protect and recover the heart from injury. Only recently has this role been shown to depend on the activity of the underappreciated dorsal motor nucleus of the vagus (DMV). By combining neural tracing, transcriptomics, and anatomical mapping in male and female Sprague-Dawley rats, we characterize cardiac-specific neuronal phenotypes in the DMV. We find that the DMV cardiac-projecting neurons differentially express pituitary adenylate cyclase-activating polypeptide (PACAP), cocaine- and amphetamine-regulated transcript (CART), and synucleins, as well as evidence that they participate in neuromodulatory co-expression involving catecholamines. The significance of these findings is enhanced by previous knowledge of the role of PACAP at the heart and of the other neuromodulators in peripheral vagal targets.

microRNA expression profiling of the response of the dorsal motor nucleus of the vagus to physiological perturbations and cardiac injury

Project description:We developed microRNA expression profiling data from the dorsal motor nucleus of the vagus (DMV) neurons under homeostasis and following physiological perturbations of remote ischemic preconditioning and cardiac ischemia. Male Sprague-Dawley rats were subjected to remote ischemia preconditioning (rIPC), ligation of the left anterior descending artery (LAD), or rIPC with LAD following two hours later (rIPC 2h/LAD). All samples were collected 24 hours after LAD.

Modulation of brain dead induced inflammation by vagus nerve stimulation

Project description:Because the vagus nerve is implicated in control of inflammation, we investigated if brain death causes impairment of the parasympathetic nervous system, hence contributing to inflammation. Brain death (BD) was induced in rats. Anaesthetised ventilated rats (NBD) served as control. Heart rate variability (HRV) was assessed by ECG. The vagus nerve was electrically stimulated (BD+STIM) during BD. Intestine, kidney, heart and liver were harvested after 6h. Affymetrix chip- analysis was performed on intestinal RNA. Quantitative PCR was performed on all organs. Serum was collected to assess TNFÎ± concentrations. Renal transplantations were performed to address the influence of vagus nerve stimulation on graft outcome. HRV was significantly lower in BD animals. Vagus nerve stimulation inhibited the increase in serum TNFÎ± concentrations and resulted in down-regulation of a multiplicity of pro-inflammatory genes in intestinal tissue. In renal tissue vagal stimulation significantly decreased the expression of E-selectin, IL1Î² and ITGA6. Renal function was significantly better in recipients that received a graft from a BD+STIM donor. Our study demonstrates impairment of the parasympathetic nervous system during BD and inhibition of serum TNFÎ± through vagal stimulation. Vagus nerve stimulation variably affected gene expression in donor organs and improved renal function in recipients. Gene expression in brain dead (BD) induced rat (with and without vagal stimulation) was compared with that of Non brain-dead ventilated control (NBD)

Single cell gene expression profiling of the response of the dorsal motor nucleus of the vagus neurons to remote ischemic preconditioning [DMV_RIPC_RT-PCR]

Project description:We developed a mesoscale single cell transcriptomics data from hundreds of the dorsal motor nucleus of the vagus (DMV) neurons under homeostasis and following physiological perturbations. Our results revealed that homeostatic DMV neuronal states can be organized into distinguishable input-output signal processing units. Remote ischemic preconditioning induced a distinctive shift in the neuronal states towards diminishing the role of inhibitory inputs.
