Constancy of olfactory cilia in rodents.

ABSTRACT: In terrestrial mammals, odorant receptors and associated sensory transduction machinery in olfactory sensory neurons (OSNs) are compartmentalized in the cilia, a critically important organelle for odor detection. The large number and length of olfactory cilia provide an extensive receptive surface for odor detection. The stability of these organelles is critical for olfactory function, as damage to olfactory cilia due to environmental factors, age, or disease impairs odor detection. However, it is unclear if there are innate structural or functional features of olfactory cilia that vary between OSN subtypes and affect the fidelity of the odorant receptive field. Using ciliary-targeted fluorescent probes, we analyzed cilia morphology in live, intact OSNs in situ from mice and rats. This unb
