多种类型的细胞表面受体和离子通道参与检测环境刺激的变化,从而影响动物行为。在许多种类的离子通道中,瞬时受体电位(TRP)阳离子通道在几乎所有感觉模态中都有贡献,并且在控制一系列令人生畏的行为方面是值得注意的。TRP通道似乎在所有后生动物生物体中是保守的,包括蠕虫、昆虫和人类。苍蝇编码13个TRP,其中大部分在感觉神经元中表达和起作用,并影响从趋光性到趋热性,重力轴,避免有害的味觉和气味以及本体感受的行为。TRP缺陷导致多种疾病,苍蝇为剖析“TRPopathies”的潜在机制提供了一个很好的动物模型。果蝇TRP还在植物来源的昆虫驱避剂的感觉中起作用,并且昆虫害虫中的相关TRP是开发改进的驱避剂以对抗昆虫传播的疾病的潜在靶标。
Multiple classes of cell surface receptors and ion channels participate in the detection of changes in environmental stimuli, and thereby influence animal behavior. Among the many classes of ion channels, Transient Receptor Potential (TRP) cation channels are notable in contributing to virtually every sensory modality, and in controlling a daunting array of behaviors. TRP channels appear to be conserved in all metazoan organisms including worms, insects and humans. Flies encode 13 TRPs, most of which are expressed and function in sensory neurons, and impact behaviors ranging from phototaxis to thermotaxis, gravitaxis, the avoidance of noxious tastants and smells and proprioception. Multiple diseases result from defects in TRPs, and flies provide an excellent animal model for dissecting the mechanisms underlying “TRPopathies.” Drosophila TRPs also function in the sensation of botanically derived insect repellents, and related TRPs in insect pests are potential targets for the development of improved repellents to combat insect-borne diseases.
