| Popis: |
We have been studying the transduction mechanisms of insect taste cells, using mainly the sugar receptor neuron in the largest labellar chemosensory hair (the taste hair). This taste hair consists of two lumina: the inner and outer lumen. The inner lumen contains four sensory dendrites of taste neurons of primary sensory cell types: sugar receptor, water receptor, and two kinds of salt receptors. The outer lumen has a much larger cross section and is filled only with the receptor lymph secreted from the folded membrane of the supporting cells [1]. When the taste hair tip is stimulated by stimulant solutions, the receptor current flows within the outer lumen from the base toward the tip and passes the ion-permeable cuticle layer at the tip; it probably flows into the sensory dendrite of the stimulated neuron to cause the receptor potential and then evoke action potentials [2–4]. |
