Alcayaga, Carmen; Varas, Rodrigo; Valdés, Viviana; Cerpa, Verónica; Arroyo, Jorge; Iturriaga, Rodrigo; Alcayaga Urbina, Julio (ELSEVIER SCIENCE BV, 2007-02)Chemoreceptor (glomus) cells of the carotid body are synaptically connected to the sensory nerve endings of petrosal ganglion (PG) neurons. In response to natural stimuli, the glomus cells release transmitters,which ...

Rey, Sergio; Río, Rodrigo del; Alcayaga Urbina, Julio; Iturriaga, Rodrigo (BLACKWELL, 2004-10-15)The carotid body (CB) chemoreceptors may play an important role in the enhanced hypoxic ventilatory response induced by chronic intermittent hypoxia (CIH). We studied the effects of cyclic hypoxic episodes of short duration ...

Iturriaga, Rodrigo; Varas, Rodrigo; Alcayaga Urbina, Julio (2007)The petrosal ganglion (PG) contains the somata of primary afferent neurons that innervate the chemoreceptor (glomus) cells in the carotid body (CB). The most accepted model of CB chemoreception states that natural stimuli ...

Varas, Rodrigo; Valdés, Viviana; Iturriaga-Vásquez, Patricio; Cassels Niven, Bruce; Iturriaga, Rodrigo; Alcayaga Urbina, Julio (ELSEVIER, 2006-02-09)Petrosal ganglion neurons are depolarized and fire action potentials in response to acetylcholine and nicotine. However, little is known about the subtype(s) of nicotinic acetylcholine receptors involved, although alpha 4 ...

Rey, Sergio; Río, Rodrigo del; Alcayaga Urbina, Julio; Iturriaga, Rodrigo (ELSEVIER SCIENCE BV, 2006-01-19)In response to hypoxia, chemoreceptor cells of the carotid body (CB) release transmitters, which acting on the petrosal ganglion (PG) neuron terminals, increase the chemoafferent discharge. Additionally, vasoactive ...

Río, Rodrigo del; Moya, Esteban A.; Koenig, Cecilia S.; Fujiwara, Kunio; Alcayaga Urbina, Julio; Iturriaga, Rodrigo (ELSEVIER, 2008-12-31)Histamine has been proposed to be an excitatory transmitter between the carotid body (CB) chemoreceptor (glomus) cells and petrosal ganglion (PG) neurons. The histamine biosynthetic pathway, its storage and release, as ...

Iturriaga, Rodrigo; Alcayaga Urbina, Julio (ELSEVIER, 2004-12)The carotid body (CB) is the main arterial chemoreceptor. The most accepted model of arterial chemoreception postulates that carotid body glomus (type 1) cells are the primary receptors, which are synaptically connected ...

Sülz, Lorena; Astorga, Guadalupe; Bellette, Bernadette; Iturriaga, Rodrigo; Mackay Sim, Alan; Bacigalupo Vicuña, Juan (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009-02-05)Nitric oxide regulates neurogenesis in the developing and adult brain. The olfactory epithelium is a site of neurogenesis in the adult and previous studies suggest a role for nitric oxide in this tissue during development. We ...

Gila, Pilar M.; Gurovich, Luis; Schaffer, Bruce; Alcayaga Urbina, Julio; Rey, Sergio; Iturriaga, Rodrigo (ELSEVIER, 2008)Phytomonitoring techniques for irrigation of avocado orchards indicate that plants respond very rapidly to fluctuations in soil water content. Root to leaf abscicic acid transport cannot fully explain the almost immediate ...
