Opposing expression pattern of opsin 3 and opsin 5 in the developing and adult nasal epithelium.

ABSTRACT: In the nasal cavity, olfactory receptor neurons are situated in the sensory epithelium and act to transduce odor signals, whereas the respiratory epithelium is responsible for removing unwanted particles from inhaled air. Although several molecular markers have been identified to define multiple specific cell types in the sensory epithelium, less is known to indicate cells in the respiratory domain. We have recently shown that the non-visual photoreceptor opsin 3 (Opn3) is expressed in the developing olfactory region. This raised the question as to which functional role/s Opn3 might play in the nasal epithelium, as well as whether other non-visual photoreceptors may be expressed in this region. By using Opn3-eGFP and Opn5-tdTomato reporter mice in combination with Foxj1, Ker8, OMP, Sox2, a
