Project description:The transcription factor Egr3 has been shown to have a cell autonomous role in sympathetic nervous system (SNS) development. We utilized microarray analysis to identify potential downstream target genes deregulated with loss of Egr3. Both conditions were in the null Bax background to prevent apoptosis and therefore mitigate identification of apoptosis related genes. Our analysis identified genes involved in biological processes that were expected such as SNS development and axonogenesis as well as those that were unexpected such as dendritogenesis and axon guidance. This led us to investigate whether Egr3 is important in these unexpected biological processes within sympathetic neurons. Total RNA was obtained from superior cervical ganglion (SCG) dissected from P0 mice with the genotype of Egr3+/+; Bax-/- or Egr3-/-; Bax-/-. Each genotype had 3 samples each.

Project description:Activation of brown fat thermogenesis increases energy expenditure and alleviates obesity. Sympathetic nervous system (SNS) is important in brown/beige adipocyte thermogenesis. Here we discover a novel fat-derived “adipokine” neurotrophic factor neurotrophin 3 (NTF3) and its receptor Tropomyosin receptor kinase C (TRKC) as key regulators of SNS growth and innervation in adipose tissue. NTF3 is highly expressed in brown/beige adipocytes, and potently stimulates sympathetic neuron neurite growth. NTF3/TRKC regulates a plethora of pathways in neuronal axonal growth and elongation. Adipose tissue sympathetic innervation is significantly increased in mice with adipocyte-specific NTF3 overexpression, but profoundly reduced in mice with TRKC haploinsufficiency (TRKC+/-). Increasing NTF3 via pharmacological or genetic approach promotes beige adipocyte development, enhances cold-induced thermogenesis and protects against diet-induced obesity (DIO); whereas TRKC+/- mice or SNS TRKC deficient mice are cold intolerant and prone to DIO. Thus, NTF3 is an important fat-derived neurotrophic factor regulating SNS innervation, energy metabolism and obesity.

Project description:The sympathetic nervous system (SNS) is pivotal in orchestrating the body's response to stress,maintaininghomeostasis, andfacilitatingadaptive physiological changes. The executing neurons responsible for these responses are localized in ganglia, positioned along the sympathetic chain. Here, we performedsingle-nucleussequencingof human sympathetic ganglia from heart healthy specimens obtained at autopsy. Unbiased clustering and trajectory analyses allowed a comprehensive analysis ofthissequencing data, offering valuable insights intoganglionic physiology includinggene expression patterns,cellular composition, intercellular communication as well as cellstatetransitions anddynamics. Strikingly, identifying previously uncharacterized cell types suggests aremarkablyhigher level of complexity than previously appreciated.Our findings highlightthe dynamic and complex physiology of sympathetic ganglia, shedding light on mechanismsgoverning fundamental physiological processes and the intricate interplay of various cell types coordinating the underlying pathways on the transcriptional level. This dataset enhances our knowledge of the SNS and opens avenues for further investigation into its role in health and disease.

Project description:Activation of the sympathetic nervous system causes pronounced metabolic changes that are mediated by multiple adrenergic receptor subtypes. Systemic treatment with β<sub>2-</sub>adrenergic receptor agonists results in multiple beneficial metabolic effects, including improved glucose homeostasis. To elucidate the underlying cellular and molecular mechanisms, we chronically treated wild-type mice and several newly developed mutant mouse strains with clenbuterol, a selective β<sub>2</sub>-adrenergic receptor agonist. Clenbuterol administration caused pronounced improvements in glucose homeostasis and prevented the metabolic deficits in mouse models of β-cell dysfunction and insulin resistance. Studies with skeletal muscle-specific mutant mice demonstrated that these metabolic improvements required activation of skeletal muscle β<sub>2</sub>-adrenergic receptors and the stimulatory G protein, G<sub>s</sub>. Unbiased transcriptomic and metabolomic analyses showed that chronic β<sub>2</sub>-adrenergic receptor stimulation caused metabolic reprogramming of skeletal muscle characterized by enhanced glucose utilization. These findings strongly suggest that agents targeting skeletal muscle metabolism by modulating β<sub>2</sub>-adrenergic receptor-dependent signaling pathways may prove beneficial as antidiabetic drugs.
