Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Temporal resolution in olfaction II: time course of recovery from adaptation in lobster chemoreceptor cells

, 1996
1. Adaptation and disadaptation rates determine the temporal response properties of sensory receptor cells. In chemoreception, temporal filter properties of receptor cells are poorly understood.

Adapt locally and act globally: strategy to maintain high chemoreceptor sensitivity in complex environments

Molecular Systems Biology, 2011
In bacterial chemotaxis, several types of ligand‐specific receptors form mixed clusters, wherein receptor–receptor interactions lead to signal amplification and integration.

Culture of arterial chemoreceptor cells from adult cats in defined medium

Brain Research, 1994
Recently patch clamp techniques and optical fluorometric techniques have been applied to freshly dissociated or cultured carotid body. However, very few studies have shown the effects of the dissociation and/or culture conditions on the health and function of the cells. The purpose of this study was to develop a culture method which support healthy and

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Investigating the role of chemotaxis operon genes in agrobacterium tumefaciens [PDF]

, 2003
A 1.7 Kb chromosomal DNA of A. tumefaciens C58C1 downstream of chemotaxis operon was sequenced completely in both directions. The comparison of this sequence with sequence databases revealed one open reading frame with strong sequence identity to MCP ...

P2Y1 receptors expressed by C1 neurons determine peripheral chemoreceptor modulation of breathing, sympathetic activity, and blood pressure

, 2013
Catecholaminergic C1 cells of the rostral ventrolateral medulla (RVLM) are key determinants of the sympathoexcitatory response to peripheral chemoreceptor activation.

Hypoxia inducible factor-dependent upregulation of Agrp in glomus type I cells of the carotid body

Molecular Metabolism
Agouti-related peptide (AgRP) is a well-established potent orexigenic peptide primarily expressed in hypothalamic neurons. Nevertheless, the expression and functional significance of extrahypothalamic AgRP remain poorly understood.
