Chirality in insect chemoreceptors
Life Sciences, 1974Abstract 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, 2014Bacteria 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
1997Abstract 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, 2000Discriminating 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, 2009While 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, 1992The 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.

Intraarterial administration of acids or perfusion with solutions inducing acidosis in the small intestine tissue, increase the afferent impulsation in the splanchnic nerves as well as the arterial pressure in anesthetized cats. Threshold concentrations of lactic and carbonic acids don't exceed, at that, their normal contents in the blood and tissues ...
