Sympathetic Innervation of the Rat Adrenal Cortex and Its Effects on the Compensatory Adrenal Cortical Growth Response to Unilateral Adrenalectomy (Catecholamine, Endocrine, Splanchnic Nerve, Cell Proliferation)
… on glomerulosa cells and blood vessels. This innervation was eliminated after neonatal sympathectomy with guanethidine or 6-hydroxydopamine, but unaffected by splanchnic nerve ligation or suprarental ganglion extirpation. Sympathetic innervation was shown to mediate compensatory adrenal …

Sympathetic control of carotid body excitability in hypertension: A preclinical study
… and maintenance of hypertension via exacerbated sympathetic drive. Carotid bodies of spontaneously hypertensive (SH) rats exhibit both hypertonicity and hyperreflexia (i.e., hyper-excitability), which is not fully understood. Our aim was to test whether carotid body hyper-excitability is mediated …

Unraveling the Interaction Between Beige Adipocytes and the Sympathetic Nervous System
… to be activated by external stimuli such as the sympathetic nervous system to drive thermogenesis. Recent studies have shown that active beige adipocytes can increase energy expenditure and are associated with anti-obesity and anti-diabetes effects in mice and humans. However, the origin of beige …

Analysis of Neural Contributions to Ultradian Oscillations of Blood Pressure and Heart Rate in Dogs
… These latter two series suggest that sympathetic innervation of both the vasculature and the heart are involved in expressing these rhythms.

An electrophysiologic investigation of the normal and ischemic left ventricle
… fibrillation. It is concluded that the sympathetic division of the autonomic nervous system normally projects a beneficial activity to the myocardium; however, no sympathetic innervation (as in beta-receptor blockade) or increased sympathetic activity (as in the anxious or excited …

Genetically-programmed suicide of adrenergic cells in the mouse leads to severe left ventricular dysfunction, impaired weight gain, and symptoms of neurological dysfunction
… the adrenal glands have formed and prior to sympathetic innervation, suggesting that the heart is the first site of catecholamine production in the mouse. The function of these Pnmt+ cells in heart development remains unclear. In the present study, we test the hypothesis that (i) a genetic …

Aging and Sympathetic Neurotransmission in Two Strains of Rats that Differ in Longevity and Immune Profiles
<p>Age-related changes in sympathetic neurotransmission in immune organs may be associated with immunosenescence; however no causal relationship has been established. From previous studies in Fischer rats (F344), we have found that during middle age, sympathetic nerve activity (SNA) rises in the …
