Journal ArticleDOI
Identification of a testicular odorant receptor mediating human sperm chemotaxis.
Marc Spehr,Günter Gisselmann,Alexandra Poplawski,Jeffrey A. Riffell,Christian H. Wetzel,Richard K. Zimmer,Hanns Hatt +6 more
TL;DR: Results indicate that hOR17-4 functions in human sperm chemotaxis and may be a critical component of the fertilization process, as well as a strong chemoattractant in subsequent behavioral bioassays.
Journal ArticleDOI
Formyl peptide receptor-like proteins are a novel family of vomeronasal chemosensors
Stéphane Rivière,Ludivine Challet,Daniela Fluegge,Daniela Fluegge,Marc Spehr,Marc Spehr,Ivan Rodriguez +6 more
TL;DR: The results suggest that formyl peptide receptor-like proteins have an olfactory function associated with the identification of pathogens, or of pathogenic states.
Journal ArticleDOI
Detection and avoidance of a carnivore odor by prey
David M. Ferrero,Jamie K. Lemon,Daniela Fluegge,Stan L. Pashkovski,Wayne J. Korzan,Sandeep Robert Datta,Marc Spehr,Markus Fendt,Stephen D. Liberles +8 more
TL;DR: Data show how a single, volatile chemical detected in the environment can drive an elaborate danger-associated behavioral response in mammals, and identifies a chemical produced by predators that activates a mouse olfactory receptor and produces an innate behavioral response.
Journal ArticleDOI
Essential Role of the Main Olfactory System in Social Recognition of Major Histocompatibility Complex Peptide Ligands
TL;DR: It is shown that nonvolatile MHC class I peptides activate subsets of OSNs at subnanomolar concentrations in vitro and affect social preference of male mice in vivo, suggesting a general role for MHC peptides in chemical communication even in those vertebrates that lack a functional VNO.
Journal ArticleDOI
Murine Pheromone Proteins Constitute a Context-Dependent Combinatorial Code Governing Multiple Social Behaviors
Angeldeep W. Kaur,Tobias Ackels,Tsung-Han Kuo,Annika Cichy,Sandeepa Dey,Cristen K. Hays,Maria Kateri,Darren W. Logan,Tobias F. Marton,Marc Spehr,Lisa Stowers +10 more
TL;DR: Findings reveal that individually emitted chemical cues can be interpreted based on their combinatorial permutation and relative ratios, and they can transmit both fixed and learned information to promote multiple behaviors.
