Exchanging ligand-binding specificity between a pair of mouse olfactory receptor paralogs reveals odorant recognition principles

Horst Vogel, Horst Pick, Shuguang Yuan, Luc Veya, Olivia Baud

A multi-gene family of ~1000 G protein-coupled olfactory receptors (ORs) constitutes the molecular basis of mammalian olfaction. Due to the lack of structural data its remarkable capacity to detect and discriminate thousands of odorants remains poorly unde ...

A Distributed Formation-based Odor Source Localization Algorithm – Design, Implementation, and Wind Tunnel Evaluation

Alcherio Martinoli, Jorge Miguel Dias Almeida Rodrigues Soares, António Pedro Rodrigues de Aguiar

Robotic odor source localization is a promising tool with numerous applications in safety, search and rescue, and environmental science. In this paper, we present an algorithm for odor source localization using multiple cooperating robots equipped with che ...

Fundamental Constraints on the Abundances of Chemotaxis Proteins

Anne-Florence Raphaëlle Bitbol

Flagellated bacteria, such as Escherichia coli, perform directed motion in gradients of concentration of attractants and repellents in a process called chemotaxis. The E. coli chemotaxis signaling pathway is a model for signal transduction, but it has uniq ...

Generation and characterization of a single-chain anti-EphA2 antibody

Elisa Oricchio

Recombinant antibody phage library technology provides multiple advantages, including that human antibodies can be generated against proteins that are highly conserved between species. We used this technology to isolate and characterize an anti-EphA2 singl ...

Functional Characterization of the Mouse Olfactory Receptor mOR256-17 in Live Cells

Thamani Dahoun

Olfactory receptors (ORs) constitute the largest family of sensory membrane proteins in mammals. They play a key role within the olfactory system to recognize and discriminate a nearly unlimited number of structurally diverse odorant molecules. The molecul ...

Monitoring proliferative activities of hormone-like odorants in human breast cancer cells by gene transcription profiling and electrical impedance spectroscopy

Horst Vogel, Cathrin Brisken, Horst Pick, Samuel Terrettaz, Olivia Baud

The human estrogen receptor alpha (ER!) mediates the proliferative action of hormones in breast cancer cells by regulating the expression of target genes to control cellular functions. Current methodologies do not permit a real-time assessment of these pro ...

Complementary Function and Integrated Wiring of the Evolutionarily Distinct Drosophila Olfactory Subsystems

Pavan P Ramdya

To sense myriad environmental odors, animals have evolved multiple, large families of divergent olfactory receptors. How and why distinct receptor repertoires and their associated circuits are functionally and anatomically integrated is essentially unknown ...

Predicting Novel Binding Modes of Agonists to β Adrenergic Receptors Using All-Atom Molecular Dynamics Simulations

Ursula Röthlisberger, Ivano Tavernelli, Marilisa Neri, Stefano Vanni

Understanding the binding mode of agonists to adrenergic receptors is crucial to enabling improved rational design of new therapeutic agents. However, so far the high conformational flexibility of G protein-coupled receptors has been an obstacle to obtaini ...

Cellular Responses to Bacterial Pore-Forming Toxins

Rodrigo Manuel Gonzalez

Pore-forming toxins (PFTs) represent the largest class of bacterial protein toxins and constitute major virulence factors produced by pathogenic bacteria during infection. Pore formation appears to be an ancient form of attack, which is also found in hydro ...

Effects of Rewarding and Unrewarding Experiences on the Response to Host-induced Plant Odors of the Generalist Parasitoid Cotesia marginiventris (Hymenoptera: Braconidae)

Anthony Christopher Davison, Ingrid Ricard

Associative learning is known to modify foraging behavior in numerous parasitic wasps. This is in agreement with optimal foraging theory, which predicts that the wasps will adapt their responses to specific cues in accordance with the rewards they receive ...
