A G protein-gated K channel is activated via beta 2-adrenergic receptors and G beta gamma subunits in Xenopus oocytes [PDF]

open access: yes, 1995
In many tissues, inwardly rectifying K channels are coupled to seven- helix receptors via the Gi/Go family of heterotrimeric G proteins. This activation proceeds at least partially via G beta gamma subunits.

Olfactory decline tracks central‐to‐peripheral spread of tau pathology in Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Olfactory decline often precedes cognitive symptoms in Alzheimer's disease (AD) and is linked to tau pathology. Yet, whether tau aggregates start in peripheral olfactory structures or spread from central regions remains debated. METHODS We analyzed 34 post mortem human olfactory bulb (OB) and 2 neuroepithelium (ONE) samples across

Expression pattern analysis of odorant-binding proteins in the pea aphid Acyrthosiphon pisum [PDF]

open access: yes, 2015
Odorant-binding proteins (OBPs) are soluble proteins mediating chemoreception in insects. In previous research, we investigated the molecular mechanisms adopted by aphids to detect the alarm pheromone (E)-\u3b2-farnesene and we found that the recognition

Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Expression of pheromone binding proteins during antennal development in the gypsy moth Lymantria dispar [PDF]

open access: yes, 1989
We have identified 2 olfactory specific proteins in the gypsy moth Lymantria dispar that are uniquely associated with the male antennae, the principal olfactory organs of this animal.

Identification of Genes Involved in Chemoreception in Plutella xyllostella by Antennal Transcriptome Analysis

open access: yesScientific Reports, 2017
Perception of environmental and habitat cues is of significance for insect survival and reproduction. Odor detection in insects is mediated by a number of proteins in antennae such as odorant receptors (ORs), ionotropic receptors (IRs), odorant binding ...

Generation of Nano‐Antibodies Targeting the SNMP1 Membrane Receptor of Spodoptera littoralis Using Extracellular Vesicles

open access: yesJournal of Extracellular Biology, Volume 5, Issue 4, April 2026.
Extracellular vesicles (EVs) represent an excellent platform for the expression of recombinant membrane proteins and their use in llama immunization to generate nano‐antibodies (Nabs). In this study, we present a novel strategy, termed the multi‐layer approach, for EV immobilization in biopanning and ELISA applications.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

open access: yesInsect Science, Volume 33, Issue 2, Page 640-664, April 2026.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioral response dynamics to pheromone in Drosophila [PDF]

open access: yes, 2012
Conclusions: Our study presents evidence that Est-6 plays a role in the physiological and behavioral dynamics of sex pheromone response in Drosophila males and supports a role of Est-6 as an odorant-degrading enzyme (ODE) in male antennae.
