Physiologic regulation of heart rate and blood pressure involves connexin 36-containing gap junctions [PDF]

, 2017
Chronically elevated sympathetic nervous activity underlies many cardiovascular diseases. Elucidating the mechanisms contributing to sympathetic nervous system output may reveal new avenues of treatment.

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

What have we learned from two-pore potassium channels? Their molecular configuration and function in the human heart [PDF]

, 2012
Two-pore domain potassium channels (K2P) control excitability, stabilize the resting membrane potential below firing threshold, and accelerate repolarisation in different cells.

Chemoreception and neuroplasticity in respiratory circuits [PDF]

, 2017
The respiratory central pattern generator must respond to chemosensory cues to maintain oxygen (O2) and carbon dioxide (CO2) homeostasis in the blood and tissues. To do this, sensorial cells located in the periphery and central nervous system monitor the

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 ...

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.
