Likewise, in goldfish, Rosenblum et al.146 have characterized the interaction of the steroidal pheromone 17a, 3-dihydroxy-4-pregnen-3-one to a plasma membrane isolated from the animal s olfactory epithelium. In an attempt to elucidate the molecular basis of pheromone recognition, Cao... 

As is the case for all sensory pathways, the capacity to perceive and respond to olfactory cues (odorants) is the combined result of events that take place in both peripheral and central processing centers. These steps, which will be discussed in detail below, begin with the molecular transduction of chemical signals in the form of odorants into electrical activity by olfactory receptor neurons (ORNs) in the periphery whose axonal projections form characteristic synaptic connections with elements of the central nervous system (CNS). Within the CNS, complex patterns of olfactory signals are integrated and otherwise processed to afford recognition and ultimately, the behavioral responses to the insect s chemical environment. Within the context of pheromone recognition these responses would likely be centered on various elements of the insect s reproductive cycle.

Since the vomeronasal system is involved in pheromone recognition, a sexually dimorphic activity, and because prior studies have reported sex differences in the VNO and AOB of rats, we pursued this question in the opossum Monodelphis domestica. An additional interest was to determine if the two parts of the vomeronasal system are...

The importance of the three stereogenic centers became evident as two of the stereoisomers [(2S,3S,7S) and (2S,3R,7R)] were recognized early as sex pheromones and that other enantiomers and diastereoisomers were often found to be inhibitory to the attractive response. Recently, the sawfly pheromone field has undergone a major advance with the recognition that several sawfly species synthesize and utilize sex pheromones of different structural types than the 3,7-dimethylpentadecan-2-ols. Shorter and longer chain lengths (undecan-2-ols 2 and tridecan-2-ols 3) and an additional methyl group in position 9 or 11 (4 and 5) characterize these new pheromone discoveries (Fig. 1). With an ad-...

A wasp presumably identifies appropriate nests by odor, discriminating among very similar ant-recognition pheromones. Virtually the only chemical information available in this entire set of... 

Induction and competition experiments that included use of hybrid pheromones and synthesized pheromone fragments (10-mers) suggested a model of interaction between the PPs and their cognate HPKs. It was suggested that an unspecific and weak interaction by the C-terminal part followed by a highly specific recognition of the N-terminal part of the pheromone to its HPK takes place/ ... 

Molecular recognition underlies chemical communication, including the phenomena of taste and smell. Pheromones are chemical communicators between individuals, usually members of the same species. Pheromone action has been demonstrated in a number of mammalian species. Several of these affect reproduction. It seems likely that there are human pheromones. The role of these in human behavior is not clear.
