Mouse data hint at human pheromones

Article Abstract:

The identification of a class of protein receptor in the lining of mouse noses, which may be pheromone receptors, gives rise to the possibility of the presence of human pheromones, since the genes encoding this family of receptors are also found in humans. Experiments are being conducted to test whether there are molecules, which might be human pheromones, in human urine, sweat and vaginal fluid that can trigger the receptors, and whether the neurons manufacturing these receptors are connected in the brain in a different way from regular, smell-detecting neurons.

Chirality in elephant pheromones

Article Abstract:

The sexual activity and aggression of the elephants is linked to physical, sexual and social maturation which is mediated by the release of chemical signals such as the pheromone frontalin, which exists in two chiral forms. The enantiomers of pheromone frontalin are released by Asian elephants in a specific ratio depends on the animal's age and stage of musth, and that different responses elicited in male and female conspecifics when the ratio alters.

Identification of protein pheromones that promote aggressive behavior

Article Abstract:

An attempt is made to understand the nature of pheromones and identify the responding neurons that influence social behavior. At least two chemically distinct pheromone ligands are enough to promote male-male aggression and stimulate vomeronasal organ (VNO) neurons.
