Última Cardiovascular and ventilatory acclimatization induced by chronic intermittent hypoxia: A role for the carotid body in the pathophysiology of sleep apnea Biol. Res. ITURRIAGA,RODRIGO; REY,SERGIO; DEL RÍO,RODRIGO. Patients with obstructive sleep apnea (OSA) show augmented ventilatory, sympathetic and cardiovascular responses to hypoxia. The facilitatory effect of chronic intermittent hypoxia (CIH) on the hypoxic ventilatory response has been attributed to a potentiation of the carotid body (CB) chemosensory response to hypoxia. However, it is a matter of debate whether the effects induced by CIH on ventilatory responses to hypoxia are due to an enhanced CB activity. Recently, we studied the effects of short cyclic hypoxic episodes on cat cardiorespiratory reflexes, heart rate variability, and CB chemosensory activity. Cats were exposed to cyclic hypoxic episodes repeated during 8 hours for 4 days. Our results showed that CIH selectively enhanced ventilatory and...

EYZAGUIRRE,CARLOS. Carotid body chemoreceptors are complex secondary receptors. There are chemical and electric connections between glomus cells (GC/GC) and between glomus cells and carotid nerve endings (GC/NE). Chemical secretion of glomus cells is accompanied by GC/GC uncoupling. Chemical GC/NE transmission is facilitated by concomitant electric coupling. Chronic hypoxia reduces GC/GC coupling but increases G/NE coupling. Therefore, carotid body chemoreceptors use chemical and electric transmission mechanisms to trigger and change the sensory discharge in the carotid nerve.

ZAPATA,PATRICIO; LARRAÍN,CAROLINA. This is a review of the different experimental approaches developed to solve the problems in our progress towards a comprehensive understanding of how arterial chemoreceptors operate. An analysis is performed of the bases, advantages and limits of the following preparations: studies of ventilatory reflexes originated from carotid bodies (CBs) in the entire animal; recordings of CB chemosensory discharges in situ; CB preparations perfused in situ; CB explants in oculo; CB explants in ovo; CB preparations incubated in vitro; CB preparations superfused in vitro; CB preparations perfused and superfused in vitro; CB tissue slices in vitro; cells acutely dissociated from CBs; CB cells in tissue culture; petrosal ganglia superfused in vitro; petrosal ganglion...
