Adaptation in chemoreceptor cells

Journal of Comparative Physiology A, 1990
We determined the time course of cumulative adaptation, e.g. the recovery from the effects of prior stimulation, in glutamate-sensitive chemoreceptor cells in extracellular recordings from the walking legs of the lobster, Homarus ...

Cell and explant culture of olfactory chemoreceptor cells

Journal of Neuroscience Methods, 1985
An in vitro system for the study of maturation of rat and chick embryonic olfactory receptor cells is presented. A variety of dissociating agents, culture media and substrata were tried in attempts to obtain a preparation of mature living olfactory receptor cells readily visible in the microscope.

Reliability of chemoreceptor cell response

Journal of Comparative Physiology A, 1994
1. To determine reliability of stimulus intensity coding we measured the response variability of 30 hydroxy-L-proline sensitive chemoreceptor cells from antennules of Homarus americanus. First, cells were tested with 5 repeated presentations of 10-5M and l0-4M hydroxy-L-proline.

Carotid body chemoreceptors in dissociated cell culture

Microscopy Research and Technique, 2002
AbstractCarotid body (CB) glomus or type 1 cells act as peripheral chemoreceptors which detect changes in arterial PO2, PCO2, and pH and help maintain homeostasis via the reflex control of ventilation. Over the last ∼12 years significant progress has been made towards understanding chemotransduction mechanisms using freshly isolated or cultured type 1 ...

Twitching cells use a chemoreceptor to detect bacterial competitors

2022
AbstractBacteria live in cosmopolitan communities, where the ability to sense and respond to interspecies and environmental signals is critical for survival. We previously showed the pathogenPseudomonas aeruginosadetects secreted peptides from bacterial competitors and navigates interspecies signal gradients using pilus-based motility. Yet, it remained

Nicotinic Acetylcholine Receptor Channels in Cat Chemoreceptor Cells

2003
Neurotransmitters are likely to play a key role for hypoxic chemotransmission in the carotid body. Among several neurotransmitters, ACh appears to be a major excitatory neurotransmitter in the cat carotid body (Fitzgerald, 2000). ACh may act directly on the afferent nerve endings and generates action potentials (Hayashida et al., 1980; Zhong & Nurse ...

Oxygen‐Sensitive Potassium Channels in Chemoreceptor Cell Physiology

Annals of the New York Academy of Sciences, 2009
The characterization of the molecular mechanisms involved in low‐oxygen chemotransduction has been an active field of research since the first description of an oxygen‐sensitive K+ channel in rabbit carotid body (CB) chemoreceptor cells. As a result, a large number of components of the transduction cascade, from O2 sensors to O2‐sensitive ion channels,

Oxygen Sensing and the Electrophysiology of Arterial Chemoreceptor Cells

Physiology, 1993
The carotid bodies sense reductions in arterial oxygen tension (PO2) and stimulate the respiratory center to induce hyperventilation. Lowering PO2, detected by O2-sensitive K+ channels, evokes a selective inhibition of the K+ current of glomus cells, with an increase of cellular excitability and cytosolic Ca2+.

Evolution of Taste and Solitary Chemoreceptor Cell Systems

Brain, Behavior and Evolution, 1997
Vertebrates possess four distinct chemosensory systems distinguishable on the basis of structure, innervation and utilization: olfaction, taste, solitary chemoreceptor cells (SCC) and the common chemical sense (free nerve endings). Of these, taste and the SCC sense rely on secondary receptor cells situated in the epidermis and synapsing on sensory ...
