Muscarinic acetylcholine receptors M2 are upregulated in the atrioventricular nodal tract in horses with a high burden of second-degree atrioventricular block

Frontiers in Cardiovascular Medicine, 2023
BackgroundSecond-degree atrioventricular (AV) block at rest is very common in horses. The underlying molecular mechanisms are unexplored, but commonly attributed to high vagal tone.AimTo assess whether AV block in horses is due to altered expression of ...

Leptin suppresses development of GLP-1 inputs to the paraventricular nucleus of the hypothalamus

eLife, 2020
The nucleus of the solitary tract (NTS) is critical for the central integration of signals from visceral organs and contains preproglucagon (PPG) neurons, which express leptin receptors in the mouse and send direct projections to the paraventricular ...

The Phantom Satiation Hypothesis of Bariatric Surgery

Frontiers in Neuroscience, 2021
The excitation of vagal mechanoreceptors located in the stomach wall directly contributes to satiation. Thus, a loss of gastric innervation would normally be expected to result in abrogated satiation, hyperphagia, and unwanted weight gain.
