Sentences with phrase «pheromone receptors»
Pheromone receptors are specialized sensors in animals and insects that detect chemical signals called pheromones, which are released by other members of their species. These receptors help them communicate, attract mates, and perform other social behaviors. Full definition
The next step, she says, will be to determine whether TAARs actually work like pheromone receptors in live animals.

These hairs contain specialized neurons, nerve cells that express pheromone receptors which are activated when they bind to individual pheromone components.
Sexual dimorphism in pheromone receptor expression has been reported in rats [20], but the best defined mammalian example is the detection of the male - specific pheromone ESP1 by Vmn2r116, which is capable of eliciting lordosis behavior specifically in female mice.
The researchers determined that the Gp - 9 protein is most similar to a moth pheromone receptor.
Monogyne workers tending their queen possibly have more sensitive pheromone receptors than do some polygynes.
These queens apparently escape attack, Krieger explains, because they are less «queenly» than BB queens and the Bb workers — which have the defective pheromone receptor — have trouble recognizing them.
This unexpected result fits with previous work showing that E and Z males have different connections between the neurons harboring pheromone receptors and the brain.
Different species have different pheromone receptors, and so the ability to most accurately smell females of the same species prevents attraction to other females.
Solving the puzzle of why a certain pheromone receptor is activated only by a specific chemical has motivated much past research.
«This result fits with our previous work showing that E and Z males have different connections between the brain and the neurons containing pheromone receptors,» explains co-author Teun Dekker.
Searching for an explanation to this alternate pheromone - detection system, neuroscientists Stephen Liberles and Linda Buck of the Fred Hutchinson Cancer Research Center in Seattle scanned the mouse olfactory epithelium for potential pheromone receptors.
These hairs contain specialised neurons, nerve cells that express pheromone receptors that are activated when they bind to individual pheromone components.
In both cases, both components are absolutely necessary for attraction, and males of both strains can smell both, with similar or identical antennal structures and pheromone receptors.
By crossing the E and Z strains in the laboratory and mapping the gene governing male preference, the researchers found that the pheromone receptors had little or no effect.
At one location or locus known as P / R, genes encode pheromones and pheromone receptors that help the fungus recognize compatible mating types.
Individuals with low expression of a pheromone receptor are more inclined to explore and are fitter in environments with scattered food resources.
«Our previous work in mapping the pheromone receptors of the European Corn Borer convinced us that this species doesn't fit the mold, and so we took another approach,» says lead author Fotini Koutroumpa.
The work contributes to a growing appreciation of the molecular diversity of olfactory and pheromone receptors, says Catherine Dulac, a neuroscientist at Harvard University.
Together with the new findings, this suggests (but doesn't prove) that TAARs are pheromone receptors, Liberles says.
