Meal parameters and vagal gastrointestinal afferents in mice that experienced early postnatal overnutrition.

Early postnatal overnutrition results in a predisposition to develop obesity due in part to hypothalamic and sympathetic dysfunction. Potential involvement of another major regulatory system component--the vagus nerve--has not been examined. Moreover, feeding disturbances have rarely been investigated prior to development of obesity when confounds due to obesity are minimized. To examine these ...

Early postnatal overnutrition: potential roles of gastrointestinal vagal afferents and brain-derived neurotrophic factor.

Abnormal perinatal nutrition (APN) results in a predisposition to develop obesity and the metabolic syndrome and thus may contribute to the prevalence of these disorders. Obesity, including that which develops in organisms exposed to APN, has been associated with increased meal size. Vagal afferents of the gastrointestinal (GI) tract contribute to regulation of meal size by transmitting satiati...

Ghrelin selectively reduces mechanosensitivity of upper gastrointestinal vagal afferents.

Ghrelin is a peptide released from gastric endocrine cells that has an orexigenic effect via a vagal pathway. Here we determine the effect of ghrelin on mechanosensitivity of upper-intestinal vagal afferent fibers in ferret and mouse. The responses of gastroesophageal vagal afferents to graded mechanical stimulation were determined in vitro before and during application of ghrelin to their peri...

Activation of Cardiac Vagal Afferents

Myocardial ischemia and reperfusion can evoke excitation of cardiac vagal nerve endings and activation of a cardiogenic depressor reflex (Bezold-Jarisch effect). We postulate that oxygen-derived free radicals, which are known to be produced during prolonged ischemia and reperfusion, contribute to this afferent excitation. We recorded activity from 47 chemosensitive vagal afferent fibers in 31 r...

Vagal Afferents in Spontaneously Hypertensive Rats

The aim of this study was to examine whether control of vascular resistance by vagal afferents is altered in the early as well as late stage of hypertension. We examined the effects of vagotomy on hindlimb vascular resistance as well as on arterial baroreflex control of hindlimb vascular resistance in spontaneously hypertensive rats and Wistar-Kyoto rats, 12 and 35 weeks old. Vagotomy in rats w...
