    Area of Science:

    • Olfactory Neuroscience
    • Cell Biology
    • Primate Anatomy

    Background:

    • Olfactory receptor cells are crucial for smell perception.
    • Their surface morphology influences odorant detection.
    • Previous studies have not detailed specific surface structures.

    Purpose of the Study:

    • To investigate the ultrastructure of olfactory receptor cell free surfaces.
    • To identify and describe previously uncharacterized surface features.
    • To understand the morphology of microvilli on primate olfactory cells.

    Main Methods:

    • Electron microscopy was utilized.
    • Nasal mucosa from Cynomolgus monkeys was examined.
    • Free surface morphology of olfactory receptor cells was analyzed.

    Main Results:

    • Olfactory receptor cells possess characteristic cilia.
    • Unique, delicate, lace-like filaments covering microvilli were observed.
    • These filaments varied in length and density along the microvilli.

    Conclusions:

    • A novel filamentous structure on olfactory receptor cell microvilli has been identified.
    • This finding expands the understanding of olfactory sensory neuron topography.
    • The described morphology may play a role in olfactory signal transduction.
