GABA Immunoreactivity in Chemoreceptor Cells of the Cat Carotid Body.

open access: yesACTA HISTOCHEMICA ET CYTOCHEMICA, 1999
γ-Aminobutyric acid (GABA) immunoreactivities were found by immunohistochemistry in the chemoreceptor cells of the cat carotid body at the light microscopic level. The immunohistochemical process used consisted of a strept-avidin-biotin-peroxidase method. The immunostaining was mostly weak and appeared in about one-third of the cells.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Specificity of H ion concentration as a carotid chemoreceptor stimulus

open access: yes, 1963
The present study was designed to separate quantitatively the relative contributions of (H+) and Pco2 as chemoreceptor stimuli. The integrated electrical activity from the entire Hering's nerve of the cat was measured and correlated with values of (H+),

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Elevated carotid body tonic activity contributes to ventilatory acclimatization and de‐acclimatization to high altitude at rest and during exercise

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Participants spent 13 days at high altitude (3800 m), where the reduced inspired oxygen pressure (↓PiO2$ \downarrow {P_{{\mathrm{i}}{{\mathrm{O}}_2}}}$) which elicited ventilatory acclimatization and increased inhibition of ventilation by transient hyperoxia (ΔV̇E$\Delta {\dot V_{\mathrm{E}}}$).

Location and architecture of the Caulobacter crescentus chemoreceptor array [PDF]

open access: yes, 2008
A new method for recording both fluorescence and cryo-EM images of small bacterial cells was developed and used to identify chemoreceptor arrays in cryotomograms of intact Caulobacter crescentus cells.

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

open access: yesThe 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 ...

Hemodynamic and ventilatory response to different levels of hypoxia and hypercapnia in carotid body-denervated rats

open access: yesClinics, 2013
OBJECTIVE: Chemoreceptors play an important role in the autonomic modulation of circulatory and ventilatory responses to changes in arterial O2 and/or CO2.

Networked Chemoreceptors Benefit Bacterial Chemotaxis Performance

open access: yesmBio, 2016
Motile bacteria use large receptor arrays to detect and follow chemical gradients in their environment. Extended receptor arrays, composed of networked signaling complexes, promote cooperative stimulus control of their associated signaling kinases. Here,
