Catecholaminergic microcircuitry controlling the output of airway-related vagal preganglionic neurons.
In this study, we have investigated the ultrastructure and function of the catecholaminergic circuitry modulating the output of airway-related vagal preganglionic neurons (AVPNs) in ferrets. Immunoelectron microscopy was employed to characterize the nature of catecholaminergic innervation of AVPN at the ultrastructural level. In addition, immunofluorescence was used to examine the expression of...
متن کاملActivation of α1-adrenoceptors facilitates excitatory inputs to medullary airway vagal preganglionic neurons.
In mammals, the neural control of airway smooth muscle is dominated by a subset of airway vagal preganglionic neurons in the ventrolateral medulla. These neurons are physiologically modulated by adrenergic/noradrenergic projections, and weakened α₂-adrenergic inhibition of them is indicated to participate in the pathogenesis and exacerbation of asthma. This study tests whether these neurons are...
متن کاملChemical coding for cardiovascular sympathetic preganglionic neurons in rats.
Cocaine and amphetamine-regulated transcript peptide (CART) is present in a subset of sympathetic preganglionic neurons in the rat. We examined the distribution of CART-immunoreactive terminals in rat stellate and superior cervical ganglia and adrenal gland and found that they surround neuropeptide Y-immunoreactive postganglionic neurons and noradrenergic chromaffin cells. The targets of CART-i...
متن کاملInsignificant bilateral convergence of preganglionic vagal fibers on postganglionic neurons to the canine heart.
We determined the extent of convergence of preganglionic fibers from the right and left vagus nerves on postganglionic neurons that supply the sinoatrial node in chloralose-anesthetized dogs. We administered hemicholinium-3 and stimulated the right vagus nerve at a high frequency to deplete acetylcholine from the postganglionic parasympathetic neurons supplied by that nerve. We compared the eff...
متن کاملThe characteristics of cardiac vagal preganglionic motoneurones in the dogfish.
Preganglionic vagal motoneurones supplying the heart of the dogfish have been located in the medulla by antidromic stimulation of the central cut end of the branchial cardiac branch of the vagus. They supplied axons with conduction velocities between 4.75 and 16.3 m s-1, which is similar to mammalian B fibres. Motoneurones were found in two locations: the rostromedial (N = 5) and lateral (N = 1...
