The extracellular accumulation of noradrenaline is limited by the activity of the neuronal reuptake process and by presynaptic inhibitory effects of adenosine.
WebAug 14, 2024 · Herein, we demonstrate that both physical and chemical hypoxia increase the systemic and hepatic expression of FGF21 in mice; by contrast, hypoxia induces a reduction of FGF21 expression in hepatocytes, indicating that hypoxia-induced FGF21 expression is differentially regulated in intact animals and in hepatocytes. WebCatecholamine production is regulated systemically via humoral messengers generated by the hypothalamus-pituitary-adrenal (HPA) axis, and locally by neural components of the sympathetic division of the autonomic nervous system.
