Immobility responses are induced by photoactivation of single glomerular species responsive to fox odour TMT

Nature Communications, 2017
The olfactory bulb is arranged in glomeruli defined by their olfactory receptor expression. The authors identify an olfactory receptor for fox odour, TMT, and show that activation of the glomerulus expressing that receptor in mice leads to immobility ...

Expressing exogenous functional odorant receptors in cultured olfactory sensory neurons

Neural Development, 2008
Background Olfactory discrimination depends on the large numbers of odorant receptor genes and differential ligand-receptor signaling among neurons expressing different receptors.

Transplant Antennae and Host Brain Interact to Shape Odor Perceptual Space in Male Moths. [PDF]

PLoS ONE, 2016
Behavioral responses to odors rely first upon their accurate detection by peripheral sensory organs followed by subsequent processing within the brain's olfactory system and higher centers. These processes allow the animal to form a unified impression of

Unraveling Adaptation in Eukaryotic Pathways: Lessons from Protocells [PDF]

, 2013
Eukaryotic adaptation pathways operate within wide-ranging environmental conditions without stimulus saturation. Despite numerous differences in the adaptation mechanisms employed by bacteria and eukaryotes, all require energy consumption.

Striking olfactory receptor gene repertoire expansion in Senegalese sole (Solea senegalensis)

iScience
Summary: Chemoreception through olfaction regulates essential fish behaviors, including reproduction. Fish olfactory receptor repertoire comprises four multigene families (olfactory receptors class C (OlfC), odorant receptor (OR), olfactory receptors ...

Functional Reintegration of Sensory Neurons and Transitional Dendritic Reduction of Mitral/Tufted Cells during Injury-Induced Recovery of the Larval Xenopus Olfactory Circuit

Frontiers in Cellular Neuroscience, 2017
Understanding the mechanisms involved in maintaining lifelong neurogenesis has a clear biological and clinical interest. In the present study, we performed olfactory nerve transection on larval Xenopus to induce severe damage to the olfactory circuitry ...

Revisiting olfactory receptors as putative drivers of cancer [version 1; referees: 2 approved]

Wellcome Open Research, 2017
BACKGROUND: Olfactory receptors (ORs) recognize odorant molecules and activate a signal transduction pathway that ultimately leads to the perception of smell.

High-throughput ligand profile characterization in novel cell lines expressing seven heterologous insect olfactory receptors for the detection of volatile plant biomarkers

Scientific Reports, 2023
Agriculturally important crop plants emit a multitude of volatile organic compounds (VOCs), which are excellent indicators of their health status and their interactions with pathogens and pests. In this study, we have developed a novel cellular olfactory

Downregulation of Fzd6 and Cthrc1 and upregulation of olfactory receptors and protocadherins by dietary beta-carotene in lungs of Bcmo1-/- mice. [PDF]

, 2010
An ongoing controversy exists on beneficial versus harmful effects of high beta-carotene (BC) intake, especially for the lung. To elucidate potential mechanisms, we studied effects of BC on lung gene expression.

Olfaction and Pheromones: Uncanonical Sensory Influences and Bulbar Interactions

Frontiers in Neuroanatomy, 2017
The rodent main and accessory olfactory systems (AOS) are considered functionally and anatomically segregated information-processing pathways. Each system is devoted to the detection of volatile odorants and pheromones, respectively.
