Prostaglandin pathways in duodenal chemosensing [PDF]
Journal of Gastroenterology and Hepatology, 2014 AbstractAcid‐sensing pathways, which trigger mucosal defense mechanisms in response to luminal acid, involve the rapid afferent‐mediated “capsaicin pathway” and the sustained “prostaglandin (PG) pathway.” Luminal acid quickly increases protective PG synthesis and release from epithelia, although the mechanism by which luminal acid induces PG synthesis ...

TRPV4 is the temperature-sensitive ion channel of human sperm
eLife, 2018 Ion channels control the ability of human sperm to fertilize the egg by triggering hyperactivated motility, which is regulated by membrane potential, intracellular pH, and cytosolic calcium.

Duodenal Chemosensing and Mucosal Defenses [PDF]
Digestion, 2011 The duodenal mucosa is exposed to endogenous and exogenous chemicals, including acid, CO<sub>2</sub>, bile acids and nutrients. Mucosal chemical sensors are necessary to exert physiological responses such as secretion, digestion, absorption, and motility.

The chemosensory system of the Drosophila larva: an overview of current understanding
Fly, 2022 Animals must sense their surroundings and be able to distinguish between relevant and irrelevant cues. An enticing area of research aims to uncover the mechanisms by which animals respond to chemical signals that constitute critical sensory input.

The nematode worm C. elegans chooses between bacterial foods as if maximizing economic utility
eLife, 2023 In value-based decision making, options are selected according to subjective values assigned by the individual to available goods and actions. Despite the importance of this faculty of the mind, the neural mechanisms of value assignments, and how choices

eLife, 2019 Sensation and action are necessarily coupled during stimulus perception – while tasting, for instance, perception happens while an animal decides to expel or swallow the substance in the mouth (the former via a behavior known as ‘gaping’).

Reflexion on Bio-Sourced Mosquito Repellents: Nature, Activity, and Preparation
Frontiers in Ecology and Evolution, 2020 Over the last decades, the geographical distribution of certain mosquito species carrying vector-borne diseases has considerably expanded. They represent a major health concern as they transmit pathogens causing alarming epidemics.
