Broader understanding of the transduction mechanisms in insect sugar receptors : Asignal transduction pathway involving nitric oxide

探讨了no的产生与味觉细胞兴奋机制的关系以及味觉感觉与食欲调节的关系。在糖细胞中检测到no敏感的guananylyl cyclase （sGC）参与信号转导途径，而在苦味细胞中检测到其他信号转导途径。同时也证明了果蝇在食用柠檬烯烟雾中的蔗糖后对蔗糖的厌恶行为是由于长时记忆的形成。

Relationships between NO-production and the excitation mechanisms in the taste cells and between the taste sensation and appetite regulation were investigated. NO-sensitive guanylyl cyclase (sGC) was detected and suggested to participate in the signal transduction pathways in the sugar cells, while other pathway was detected in the bitterness cells. Meanwhile it was demonstrated that the fly's aversive behavior to sucrose after their feeding sucrose in the limonene fume was due to the formation of long-term memory.
