Renal chemoreceptors

Journal of the Autonomic Nervous System, 1981
A study of the renal receptors and types of stimuli which give origin to supraspinal and spinal-mediated autonomic reflexes is presented. Multiunit and single unit recordings from the afferent renal nerves of male Sprague-Dawley rats have revealed two groups of renal chemosensitive receptors (chemoreceptors).

Chemoreceptors in the Gut

Annual Review of Physiology, 2018
The gastrointestinal tract represents the largest interface between the human body and the external environment. It must continuously monitor and discriminate between nutrients that need to be assimilated and harmful substances that need to be expelled.

Positioning of bacterial chemoreceptors

Trends in Microbiology, 2015
For optimum growth, bacteria must adapt to their environment, and one way that many species do this is by moving towards favourable conditions. To do so requires mechanisms to both physically drive movement and provide directionality to this movement.

Melatonin enhances the hypoxic response of rat carotid body chemoreceptor

Journal of Pineal Research, 2005
Melatonin attenuates carotid chemoreceptor response to hypercapnic acidosis and may contribute to the effect of circadian rhythms on the chemoreflex. The purpose of this study was to test the hypothesis that melatonin modulates rat carotid chemoreceptor ...

Chirality in insect chemoreceptors

Life Sciences, 1974
Abstract Conditioned honeybee workers can discriminate between enantiomeric pairs which are both congruous and incongruous odorants for human beings. These results are discussed in terms of appropriately chiral chemoreceptors, which would enable honeybee workers to distinguish floral odor sources that differ only in enantiomeric identity.

Bacterial chemoreceptors and chemoeffectors

Cellular and Molecular Life Sciences, 2014
Bacteria use chemotaxis signaling pathways to sense environmental changes. Escherichia coli chemotaxis system represents an ideal model that illustrates fundamental principles of biological signaling processes. Chemoreceptors are crucial signaling proteins that mediate taxis toward a wide range of chemoeffectors.

Nature of chemoreceptor stimuli and chemoreceptor responses

1997
Abstract The carotid and aortic bodies are stimulated by natural blood-borne agents, hypoxia, hypercapnia, and acidaemia. There are interactions between these variables so that the effects of hypoxia are greater in the presence of a raised PaCO2 or a reduction in pHa.

Selectivity of chemoreceptor neuron

Biosystems, 2000
Discriminating ability (selectivity) of chemoreceptor neuron is compared with that of its receptor proteins. The process of neuronal triggering is expected to be cooperative and threshold-type in a sense that the neuron can fire if and only if the number of its receptor proteins, which are bound with odor molecules, is above a definite threshold.

The Electrophysiology of Gastrointestinal Chemoreceptors

Digestion, 2009
While the complexity of the reflex responses of the alimentary canal to chemical stimulation is appreciated, detailed analysis of the receptor mechanisms has yet to be made. This gap in our knowledge remains in spite of recent progress in understanding of peripheral sensory mechanisms in other regions of the body and offers a continuing challenge to ...

Chemoreceptor control of the airways

Respiration Physiology, 1992
The peripheral chemoreceptors act reflexly not only on respiration, but also on many motor systems in the respiratory tract. They cause a reflex bronchoconstriction, although this may be modified or even reversed by secondary dilator reflexes such as that from pulmonary stretch receptors.
