Binding of the General Odorant Binding Protein of Bombyx mori BmorGOBP2 to the Moth Sex Pheromone Components

, 2010
Insects use olfactory cues to locate hosts and mates. Pheromones and other semiochemicals are transported in the insect antenna by odorant-binding proteins (OBPs), which ferry the signals across the sensillum lymph to the olfactory receptors (ORs).

Genomic content of chemosensory genes correlates with host range in wood-boring beetles (Dendroctonus ponderosae, Agrilus planipennis, and Anoplophora glabripennis)

BMC Genomics, 2019
Background Olfaction and gustation underlie behaviors that are crucial for insect fitness, such as host and mate selection. The detection of semiochemicals is mediated via proteins from large and rapidly evolving chemosensory gene families; however, the ...

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Structural and biochemical evaluation of Ceratitis capitata odorant-binding protein 22 affinity for odorants involved in intersex communication

, 2019
In insects, odorant-binding proteins (OBPs) connect the peripheral sensory system to receptors of olfactory organs. Medfly Ceratitis capitata CcapObp22 shows 37% identity and close phylogenetic affinities with Drosophila melanogaster OBP69a ...

Neuromorphic Devices and Computing for Sensing, Memory, and Control

Advanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Functional Specialization of Respiratory and Olfactory Mucus Revealed by Proteomic Profiling

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Mucus overlies the nasal mucosa in the respiratory and olfactory regions, which perform distinct physiological functions. However, proteomic differences between respiratory mucosa (RM) and olfactory cleft (OC) mucus remain unclear.

Use of a Bacteriophage Lysin to Control Axillary Malodor

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Axillary malodor is primarily caused by bacteria, particularly Staphylococcus hominis, which metabolize apocrine secretions into volatile compounds. Traditional deodorants contain antiseptics that can disrupt the skin microbiome and cause irritation. Alternative methods of odor control are being sought but so far without success. We

Odorant Binding Changes the Electrical Properties of Olfactory Receptors at the Nanoscale [PDF]

, 2021
The transduction of odorant binding into cellular signaling by olfactory receptors (ORs) is not understood and knowing its mechanism would enable developing new pharmacology and biohybrid electronic detectors of volatile organic com-pounds bearing high ...

Theoretical Analysis of Androstenone Adsorption on Chimpanzee and Gorilla Olfactory Receptors (G‐Protein): Statistical Physics Modeling, Molecular Docking Simulation, and Thermodynamic Investigation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT An advanced theory based on statistical physics was applied to microscopically investigate androstenone adsorption and its relationship with olfactory perception in chimpanzees and gorillas. For this purpose, dose–response curves of androstenone on olfactory receptors of chimpanzee OR7D4 and gorilla OR7D4 were analyzed by statistical physics ...

Specific involvement of two amino acid residues in cis -nerolidol binding to odorant-binding protein 5 AlinOBP5 in the alfalfa plant bug, Adelphocoris lineolatus (Goeze)

, 2013
Olfaction plays an important role in insects' survival and reproduction. Odorant-binding proteins (OBPs) are considered to be one of the crucial proteins in the insect olfactory pathway.
