Caffeine decreases exhaled nitric oxide.
BACKGROUND Caffeine is known to inhibit phosphodiesterases, to mobilise intracellular calcium, and to act as an antagonist at adenosine receptors, all of which can potentially alter nitric oxide (NO) production. It was therefore hypothesised that caffeine may alter exhaled NO (eNO) levels. METHODS In a randomised, single blind, crossover manner, 12 normal subjects consumed either (1) coffee a...
متن کاملModulation of serotonergic neurotransmission by nitric oxide.
Nitric oxide (NO) and serotonin (5-HT) are two neurotransmitters with important roles in neuromodulation and synaptic plasticity. There is substantial evidence for a morphological and functional overlap between these two neurotransmitter systems, in particular the modulation of 5-HT function by NO. Here we demonstrate for the first time the modulation of an identified serotonergic synapse by NO...
متن کاملNitric oxide as a mediator of nonadrenergic noncholinergic neurotransmission.
Part of the regulation of gastrointestinal (GI) smooth muscles is provided by nonadrenergic noncholinergic (NANC) nerves. Stimulation of these nerves, either by field stimulation or via neural reflex pathways, elicits hyperpolarization of postjunctional smooth muscle membranes referred to as inhibitory junction potentials and relaxation. The transmitter(s) that mediate NANC inhibitory neural tr...
متن کاملDifferential modulation of gonadotropin responses to kisspeptin by aminoacidergic, peptidergic, and nitric oxide neurotransmission.
Kisspeptins (Kp), products of the Kiss1 gene, have emerged as essential elements in the control of GnRH neurons and gonadotropic secretion. However, despite considerable progress in the field, to date limited attention has been paid to elucidate the potential interactions of Kp with other neurotransmitters known to centrally regulate the gonadotropic axis. We characterize herein the impact of m...
متن کاملAlternatives to nitric oxide.
Inhaled nitric oxide (INO) is a selective pulmonary vasodilator that has the ability to produce vasodilation in the pulmonary vascular bed without causing it in the systemic circulation. This property of INO has made it a useful therapy in the management of both adult and paediatric patients with a variety of conditions associated with pulmonary hypertension (PH), with or without hypoxia. Toxic...
