Duodenal chemosensing [PDF]

open access: yesCurrent Opinion in Gastroenterology, 2018
Luminal chemosensing is a term used to describe how small molecules in the gut lumen interact with the host through surface receptors or via transport into the submucosa. In this review, we have summarized recent advances of understanding luminal chemosensing in the gastroduodenal mucosa, with a particular emphasis on how chemosensing affects mucosal ...

Gut chemosensing mechanisms [PDF]

open access: yesJournal of Clinical Investigation, 2015
The enteroendocrine system is the primary sensor of ingested nutrients and is responsible for secreting an array of gut hormones, which modulate multiple physiological responses including gastrointestinal motility and secretion, glucose homeostasis, and appetite.

Chemosensing on Miniaturized Plasmonic Substrates [PDF]

open access: yesMicromachines, 2021
Round, small-sized coverslips were coated for the first time with thin layers of indium tin oxide (ITO, 10–40 nm)/gold (Au, 2–8 nm) and annealed at 550 °C for several hours. The resulting nanostructures on miniaturized substrates were further optimized for the localized surface plasmon resonance (LSPR) chemosensing of a model molecule—1,2-bis-(4 ...

New Perspectives on Classical Alarmin Responses to Intestinal Helminth Infection. [PDF]

open access: yesParasite Immunol
ABSTRACT Interleukins 33, 25, and thymic stromal lymphopoietin (TSLP) are core components of type two immune responses and have been studied extensively using helminth infection models. However, many questions remain regarding their cellular sources, their immune recipients, as well as how they shape immunity.

Trigeminal Chemosensation [PDF]

open access: yes, 2003
In this chapter, basic aspects of the anatomy, physiology, and chemical responsiveness of the human trigeminal system were reviewed. Additionally, studies demonstrating that ocular trigeminal sensitivity may be similar to intranasal trigeminal sensitivity were reviewed.

The Structure and Function of Ionotropic Receptors in Drosophila

open access: yesFrontiers in Molecular Neuroscience, 2021
Ionotropic receptors (IRs) are a highly divergent subfamily of ionotropic glutamate receptors (iGluR) and are conserved across Protostomia, a major branch of the animal kingdom that encompasses both Ecdysozoa and Lophothrochozoa.

Intrinsic and Synaptic Dynamics Contribute to Adaptation in the Core of the Avian Central Nucleus of the Inferior Colliculus

open access: yesFrontiers in Neural Circuits, 2019
The reduction of neuronal responses to repeated stimulus presentation occurs in many sensory neurons, also in the inferior colliculus of birds. The cellular mechanisms that cause response adaptation are not well described.

Effects of Mating on Gene Expression in Female Insects: Unifying the Field

open access: yesInsects, 2022
There is intense interest in controlling insect reproductive output. In many insect species, reproductive output is profoundly influenced by mating, including the receipt of sperm and seminal fluid molecules, through physiological and behavior changes ...

CO2 chemosensing in rat oesophagus [PDF]

open access: yesGut, 2008
Acid in the oesophageal lumen is often sensed as heartburn. It was hypothesised that luminal CO(2), a permeant gas, rather than H(+), permeates through the epithelium, and is converted to H(+), producing an afferent neural signal by activating chemosensors.The rat lower oesophageal mucosa was superfused with pH 7.0 buffer, and pH 1.0 or pH 6.4 high CO ...

Mutually Exclusive Expression of Closely Related Odorant-Binding Proteins 9A and 9B in the Antenna of the Red Flour Beetle Tribolium castaneum

open access: yesBiomolecules, 2021
Olfaction is crucial for insects to find food sources, mates, and oviposition sites. One of the initial steps in olfaction is facilitated by odorant-binding proteins (OBPs) that translocate hydrophobic odorants through the aqueous olfactory sensilla ...
