| Research Abstract |
Olfactory sensory neurons (OSNs) expressing a given odorant receptor project axons to a pair of fixed glomeruli on the olfactory bulb to form a topographic map. In this study, we revealed that some BMP family members are variously expressed in olfactory epithelium (OE) during development. BMP7 and Pax6 are specifically expressed in a unique subset of OSNs, termed Car2 OSNs, which exists in the ventro-lateral region of the OE and is known to respond to CO_2 We found that Pax6 regulates the establishment of the signaling cascade of Car2 OSNs.
