Combining the Classification and Pharmacophore Approaches to Understand Homogeneous Olfactory Perceptions at Peripheral Level: Focus on Two Aroma Mixtures

Molecules, 2023
The mechanisms involved in the homogeneous perception of odorant mixtures remain largely unknown. With the aim of enhancing knowledge about blending and masking mixture perceptions, we focused on structure-odor relationships by combining the ...

Wiring the senses: Factors that regulate peripheral axon pathfinding in sensory systems

Developmental Dynamics, Volume 252, Issue 1, Page 81-103, January 2023., 2023
Abstract Sensory neurons of the head are the ones that transmit the information about the external world to our brain for its processing. Axons from cranial sensory neurons sense different chemoattractant and chemorepulsive molecules during the journey and in the target tissue to establish the precise innervation with brain neurons and/or receptor ...

Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...

Honeybees learn odour mixtures via a selection of key odorants. [PDF]

PLoS ONE, 2010
The honeybee has to detect, process and learn numerous complex odours from her natural environment on a daily basis. Most of these odours are floral scents, which are mixtures of dozens of different odorants.

Active aroma compounds assessment of processed and non-processed micro- and macroalgae by solid-phase microextraction and gas chromatography/mass spectrometry targeting seafood analogs

Frontiers in Sustainable Food Systems, 2022
The odor of four algae was investigated and compared to evaluate the potential of these algae to mimic shrimp aroma. Solid-phase microextraction followed by gas chromatography analysis coupled with sensory analysis was used for performance assessment ...

The appearance of phagocytic microglia in the postnatal brain of Niemann Pick type C mice is developmentally regulated and underscores shortfalls in fine odor discrimination

Journal of Cellular Physiology, Volume 237, Issue 12, Page 4563-4579, December 2022., 2022
Abstract The loss of NPC1 or NPC2 function results in cholesterol and sphingolipid dyshomeostasis that impairs developmental trajectories, predisposing the postnatal brain to the appearance of pathological signs, including progressive and stereotyped Purkinje cell loss and microgliosis.

Phosphoinositide 3-kinase dependent inhibition as a broad basis for opponent coding in Mammalian olfactory receptor neurons. [PDF]

PLoS ONE, 2013
Phosphoinositide 3-kinase (PI3K) signaling has been implicated in mediating inhibitory odorant input to mammalian olfactory receptor neurons (ORNs).

High‐throughput behavioral phenotyping of tiny arthropods: Chemosensory traits in a mesostigmatic hematophagous mite

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 46-62, January 1, 2023., 2023
We validated a new high‐throughput system based on nanocomputers connected to cameras automatically tracking movements of single mites. Our results confirm the existence of a volatile pheromone deposited by D. gallinae and attractive to conspecifics.

Ontogenetic shifts in olfactory rosette morphology of the sockeye salmon, Oncorhynchus nerka

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023
Scanning electron microscope images of sockeye salmon olfactory rosette. Olfactory rosette size linearly increases with lamellae number throughout ontogeny. The complexity of the rosette, including the distribution of sensory and nonsensory epithelia, and the appearance of secondary lamellar folding, varies between fry and adult life stages.
