Subdiaphragmatic vagal afferent nerves modulate visceral pain.
Activation of the vagal afferents by noxious gastrointestinal stimuli suggests that vagal afferents may play a complex role in visceral pain processes. The contribution of the vagus nerve to visceral pain remains unresolved. Previous studies reported that patients following chronic vagotomy have lower pain thresholds. The patient with irritable bowel syndrome has been shown alteration of vagal ...
متن کاملTonic postganglionic sympathetic inhibition induced by afferent renal nerves?
Other than efferent sympathetic innervation, the kidney has peptidergic afferent fibers expressing TRPV1 receptors and releasing substance P. We tested the hypothesis that stimulation of afferent renal nerve activity with the TRPV1 agonist capsaicin inhibits efferent renal sympathetic nerve activity tonically by a neurokinin 1 receptor-dependant mechanism. Anesthetized Sprague-Dawley rats were ...
متن کاملRole of afferent renal nerves in spontaneous hypertension in rats.
In the present study we examined sympathetic function and baroreceptor reflex sensitivity in adult spontaneously hypertensive rats (SHR) after a selective transection of afferent renal nerves in the prehypertensive and established phases of hypertension. Renal deafferentation performed between 3 and 4 weeks after birth did not influence the course of the development of high blood pressure when ...
متن کاملCapsaicin-Sensitive Afferent Nerves and the Human Gastrointestinal Tract
Capsaicin activates the capsaicin (vanilloid) receptor expressed a subgroup of primary afferent nociceptive neurons (Szolcsányi, 2004). The capsaicin receptor has been cloned (Caterina et al., 1997) and turned out to be a cation channel. It is gated besides capsaicin and other capsaicinoids (some vanilloids) by low pH, noxious heat and various pains – producing endogenous and exogenous chemical...
متن کاملActivation of afferent renal nerves modulates RVLM-projecting PVN neurons.
Renal denervation for the treatment of hypertension has proven to be successful; however, the underlying mechanism/s are not entirely clear. To determine if preautonomic neurons in the paraventricular nucleus (PVN) respond to afferent renal nerve (ARN) stimulation, extracellular single-unit recording was used to investigate the contribution of the rostral ventrolateral medulla (RVLM)-projecting...
