Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

Expressing exogenous functional odorant receptors in cultured olfactory sensory neurons

Neural Development, 2008
Background Olfactory discrimination depends on the large numbers of odorant receptor genes and differential ligand-receptor signaling among neurons expressing different receptors.

Signal Amplification in Drosophila Olfactory Receptor Neurons [PDF]

Neuron, 2019
Olfactory receptor neurons (ORNs) transform scant chemical inputs into significant neural signals. This transformation requires signal amplification. In this issue of Neuron, Ng et al. (2019) identified a mechanism by which the signals evoked by pheromones are amplified in the ORNs that selectively promote courtship behavior in Drosophila.

Signaling by olfactory receptor neurons near threshold [PDF]

Proceedings of the National Academy of Sciences, 2010
An important contributing factor for the high sensitivity of sensory systems is the exquisite sensitivity of the sensory receptor cells. We report here the signaling threshold of the olfactory receptor neuron (ORN). We first obtained a best estimate of the size of the physiological electrical response successfully triggered by a single odorant-binding ...

CD36 is involved in oleic acid detection by the murine olfactory system.

Frontiers in Cellular Neuroscience, 2015
Olfactory signals influence food intake in a variety of species. To maximize the chances of finding a source of calories, an animal’s preference for fatty foods and triglycerides already becomes apparent during olfactory food search behavior.

Cholinergic calcium responses in cultured antennal lobe neurons of the migratory locust

Scientific Reports, 2021
Locusts are advantageous organisms to elucidate mechanisms of olfactory coding at the systems level. Sensory input is provided by the olfactory receptor neurons of the antenna, which send their axons into the antennal lobe. So far, cellular properties of

Influence of blood meal on the responsiveness of olfactory receptor neurons in antennal sensilla trichodea of the yellow fever mosquito, Aedes aegypti [PDF]

, 2010
In female Aedes aegypti L. mosquitoes, a blood meal induces physiological and behavioral changes. Previous studies have shown that olfactory receptor neurons (ORNs) housed in grooved peg sensilla on the antennae of Ae.

Odour Transduction in Olfactory Receptor Neurons

The Chinese Journal of Physiology, 2010
The molecular mechanisms that control the binding of odorant to olfactory receptors and transduce this signal into membrane depolarization are reviewed. They are compared in vertebrates and insects for interspecific (allelochemicals) and intraspecific (pheromones) olfactory signals. Attempts to develop quantitative models of these multistage signalling

Unitary response of mouse olfactory receptor neurons [PDF]

Proceedings of the National Academy of Sciences, 2010
The sense of smell begins with odorant molecules binding to membrane receptors on the cilia of olfactory receptor neurons (ORNs), thereby activating a G protein, G olf , and the downstream effector enzyme, an adenylyl cyclase (ACIII).

The smell of blue light: a new approach towards understanding an olfactory neuronal network

Frontiers in Neuroscience, 2011
Olfaction is one of the most important senses throughout the animal kingdom. It enables animals to discriminate between a wide variety of attractive and repulsive odorants and often plays a decisive role in species specific communication. In recent years
