The Odorant Receptor-Dependent Role of Olfactory Marker Protein in Olfactory Receptor Neurons [PDF]

open access: yesThe Journal of Neuroscience, 2016
Olfactory receptor neurons (ORNs) in the nasal cavity detect and transduce odorants into action potentials to be conveyed to the olfactory bulb. Odorants are delivered to ORNs via the inhaled air at breathing frequencies that can vary from 2 to 10 Hz in the mouse. Thus olfactory transduction should occur at sufficient speed such that it can accommodate

Olfactory ensheathing glia are required for embryonic olfactory axon targeting and the migration of gonadotropin-releasing hormone neurons

open access: yesBiology Open, 2013
Summary Kallmann's syndrome is caused by the failure of olfactory axons and gonadotropin-releasing hormone (GnRH) neurons to enter the embryonic forebrain, resulting in anosmia and sterility.

Resolving different presynaptic activity patterns within single olfactory glomeruli of Xenopus laevis larvae

open access: yesScientific Reports, 2021
Olfactory sensing is generally organized into groups of similarly sensing olfactory receptor neurons converging into their corresponding glomerulus, which is thought to behave as a uniform functional unit.

Odor sampling strategies in mice with genetically altered olfactory responses.

open access: yesPLoS ONE, 2021
Peripheral sensory cells and the central neuronal circuits that monitor environmental changes to drive behaviors should be adapted to match the behaviorally relevant kinetics of incoming stimuli, be it the detection of sound frequencies, the speed of ...

Calcium Signalling in Squid Olfactory Receptor Neurons

open access: yesNeurosignals, 1999
Isolated squid olfactory receptor neurons respond to dopamine and betaine with hyperpolarizing conductances. We used Ca(2+) imaging techniques to determine if changes in intracellular Ca(2+) were involved in transducing the hyperpolarizing odor responses. We found that dopamine activated release of Ca(2+) from intracellular stores while betaine did not

Purinergic receptor antagonists inhibit odorant-mediated CREB phosphorylation in sustentacular cells of mouse olfactory epithelium

open access: yesBMC Neuroscience, 2011
Background Extracellular nucleotides have long been known to play neuromodulatory roles and to be involved in intercellular signalling. In the olfactory system, ATP is released by olfactory neurons, and exogenous ATP can evoke an increase in ...

Organization of olfactory centres in the malaria mosquito Anopheles gambiae

open access: yesNature Communications, 2016
Mosquitoes use olfactory cues to locate their host. Here, Riabinina et al. use genetic labelling of olfactory receptor neurons in the malaria vector Anopheles gambiaeto show that these neurons project to the antennal lobe, a known insect olfactory centre,

Olfactory and solitary chemosensory cells: two different chemosensory systems in the nasal cavity of the American alligator, Alligator mississippiensis

open access: yesBMC Neuroscience, 2007
Background The nasal cavity of all vertebrates houses multiple chemosensors, either innervated by the Ist (olfactory) or the Vth (trigeminal) cranial nerve. Various types of receptor cells are present, either segregated in different compartments (e.g. in

GPR37 Signaling Modulates Migration of Olfactory Ensheathing Cells and Gonadotropin Releasing Hormone Cells in Mice

open access: yesFrontiers in Cellular Neuroscience, 2019
Gonadotropin releasing hormone (GnRH) neurons, part of the hypothalamic-pituitary-gonadal axis, regulate reproduction. Prenatally, GnRH neurons migrate into the brain from the nasal placode along terminal nerve fibers, intermixed with olfactory sensory ...

Recent Insights into Insect Olfactory Receptors and Odorant-Binding Proteins

open access: yesInsects, 2022
Human and insect olfaction share many general features, but insects differ from mammalian systems in important ways. Mammalian olfactory neurons share the same overlying fluid layer in the nose, and neuronal tuning entirely depends upon receptor ...
