Diversity and evolution of the vertebrate chemoreceptor gene repertoire

Nature Communications
Chemoreception – the ability to smell and taste – is an essential sensory modality of most animals. The number and type of chemical stimuli that animals can perceive depends primarily on the diversity of chemoreceptors they possess and express.

A Case for Hydrogen Sulfide Metabolism as an Oxygen Sensing Mechanism

Antioxidants, 2021
The ability to detect oxygen availability is a ubiquitous attribute of aerobic organisms. However, the mechanism(s) that transduce oxygen concentration or availability into appropriate physiological responses is less clear and often controversial.

The Gluopsins: Opsins without the Retinal Binding Lysine

Cells, 2022
Opsins allow us to see. They are G-protein-coupled receptors and bind as ligand retinal, which is bound covalently to a lysine in the seventh transmembrane domain. This makes opsins light-sensitive.

Criteria for central respiratory chemoreceptors: experimental evidence supporting current candidate cell groups

Frontiers in Physiology, 2023
An interoceptive homeostatic system monitors levels of CO2/H+ and provides a proportionate drive to respiratory control networks that adjust lung ventilation to maintain physiologically appropriate levels of CO2 and rapidly regulate tissue acid-base ...

Chemosensation and Evolution of Drosophila Host Plant Selection

iScience, 2020
The ability to respond to chemosensory cues is critical for survival of most organisms. Among insects, Drosophila melanogaster has the best characterized olfactory system, and the availability of genome sequences of 30 Drosophila species provides an ...

Bacterial vampirism mediated through taxis to serum

eLife
Bacteria of the family Enterobacteriaceae are associated with gastrointestinal (GI) bleeding and bacteremia and are a leading cause of death, from sepsis, for individuals with inflammatory bowel diseases. The bacterial behaviors and mechanisms underlying
