A recent paper by the Dahankuar laboratory suggested that single Drosophila sugar receptors proteins accurately mediate sugar detection when ectopically expressed in olfactory neurons of the antenna. These findings contra-dict numerous previously published electrophysiological and behavioral investigations, which all point towards heteromultimeric sugar taste receptors. Here, I provide some explanation why this "pseudo-heterologous" expression system may have led to this misleading conclusion.
达汉库尔实验室最近发表的一篇论文表明,单个果蝇糖受体蛋白在触角嗅觉神经元中异位表达时能准确介导糖的检测。这些发现与之前发表的众多电生理和行为学研究结果相矛盾,之前的研究均指向异源多聚体糖味觉受体。在此,我将解释为何这种“假异源”表达系统可能导致了这一误导性结论。
