Abstract

Rodents contain in their genome more than 1000 functional odorant receptor genes, which are specifically expressed by the olfactory sensory neurons projecting from the olfactory epithelium to the olfactory bulb. Strong evidence for the presence and local translation of odorant receptor mRNAs in the axon of olfactory sensory neurons was obtained, but no function has been assigned to these axonal mRNAs yet. The aim of this review is to discuss the evidence for the presence and local translation of odorant receptor mRNAs in olfactory sensory axons, and to speculate on their possible function in the wiring of the mouse olfactory sensory projections.
