Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly
Insect Molecular Biology, EarlyView.Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Odorant-Binding Proteins in Insects
, 2010 Our understanding of the molecular and biochemical mechanisms that mediate chemoreception in insects has been greatly improved after the discovery of olfactory and taste receptor proteins. However, after 50 years of the discovery of first insect sex pheromone from the silkmoth Bombyx mori, it is still unclear how hydrophobic compounds reach the ...

Journal of Chemical Ecology, 2014 Odorant binding proteins (OBPs) are believed to be important for transporting semiochemicals through the aqueous sensillar lymph to the olfactory receptor cells within the insect antennal sensilla. In this study, three new putative OBP genes, MmedOBP8-10, were identified from a Microplitis mediator (Hymenoptera: Braconidae) antennal cDNA library ...

Insect Molecular Biology, EarlyView.Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Insect Molecular Biology, EarlyView.RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Behavioural Brain Research, 2019 Olfactory function varies by several orders of magnitude among healthy individuals, who may exhibit a reduced sensitivity (hyposmia), a high sensitivity (hyperosmia), or an olfactory blindness (anosmia).

Cilia in Nervous System Development, Function, and Disease
MedComm – Future Medicine, Volume 5, Issue 2, June 2026.Cilia are evolutionarily conserved organelles that function as essential sensory and motility platforms in the nervous system. This review outlines key cilia‐dependent signaling pathways and their roles in neural development and function. Furthermore, it highlights how ciliary dysfunction can lead to a variety of neurological disorders, known as ...

A conserved odorant binding protein is required for essential amino acid detection in Drosophila
Communications Biology, 2019 Animals need to detect in the food essential amino acids that they cannot synthesize. We found that the odorant binding protein OBP19b, which is highly expressed in Drosophila melanogaster taste sensilla, is necessary for the detection of several amino ...

Humidity response depends on the small soluble protein Obp59a in Drosophila
eLife, 2018 Hygrosensation is an essential sensory modality that is used to find sources of moisture. Hygroreception allows animals to avoid desiccation, an existential threat that is increasing with climate change.
