Ozone exposure disrupts insect sexual communication

Nature Communications, 2023
Insect pheromones can be degraded by the air pollutant ozone. Jiang et al. show that ozone-exposed male flies lose their pheromones and become less attractive to females. Additionally, ozone-exposed males exhibited increased male-male courtship behaviour

Flower Production, Headspace Volatiles, Pollen Nutrients, and Florivory in Tanacetum vulgare Chemotypes

Frontiers in Plant Science, 2021
Floral volatiles and reward traits are major drivers for the behavior of mutualistic as well as antagonistic flower visitors, i.e., pollinators and florivores.

Neuronal processing of complex mixtures establishes a unique odor representation in the moth antennal lobe

Frontiers in Neural Circuits, 2011
Animals typically perceive natural odor cues in their olfactory environment as a complex mixture of chemically diverse components. In insects, the initial representation of an odor mixture occurs in the first olfactory center of the brain, the antennal ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Temporal response dynamics of Drosophila olfactory sensory neurons depends on receptor type and response polarity

Frontiers in Cellular Neuroscience, 2012
Insect olfactory sensory neurons (OSN) express a diverse array of receptors from different protein families i.e. ionotropic receptors (IR), gustatory receptors (GR) and odorant receptors (OR).

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Dimerisation of the Drosophila odorant co-receptor Orco

Frontiers in Cellular Neuroscience, 2014
Odorant receptors (ORs) detect volatile molecules and transform this external information into an intracellular signal. Insect ORs are heteromers composed of two seven transmembrane proteins, an odor-specific OrX and a coreceptor (Orco) protein.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Expression of ionotropic receptors in terrestrial hermit crab’s olfactory sensory neurons

Frontiers in Cellular Neuroscience, 2015
Coenobitidae are one out of at least five crustacean lineages which independently succeeded in the transition from water to land. This change in lifestyle required adaptation of the peripheral olfactory organs, the antennules, in order to sense chemical ...
