The cilia of rat olfactory sensory neurons incorporate glucose and may take it from the mucus to use as complementary energy source for odor transduction

Abstract

Olfactory cilia (~60 μm long, 0.2 μm diameter) project from the apical knob of the single dendrite of olfactory sensory neurons (OSNs). Odorants binding to G-protein coupled receptors trigger a cAMP-cascade in the cilia that leads to the opening of Ca2+-c
