摘要
Sensory information from the environment is required for life and survival, and it is detected by specialized cells which together make up the sensory system. The fish sensory system includes specialized organs that are able to detect mechanical and chemical stimuli. In particular, taste buds are small organs located on the tongue in terrestrial vertebrates that function in the perception of taste. In fish, taste buds occur on the lips, the flanks, and the caudal (tail) fins of some species and on the barbels of others. In fish taste receptor cells, different classes of ion channels have been detected which, like in mammals, presumably participate in the detection and/or transduction of chemical gustatory signals. However, since some of these ion channels are involved in the detection of additional sensory modalities, it can be hypothesized that taste cells sense stimuli other than those specific for taste. This mini-review summarizes current knowledge on the presence of transient-receptor potential (TRP) and acid-sensing (ASIC) ion channels in the taste buds of teleosts, especially adult zebrafish. Up to now ASIC4, TRPC2, TRPA1, TRPV1 and TRPV4 ion channels have been found in the sensory cells, while ASIC2 was detected in the nerves supplying the taste buds.

来自环境的感觉信息对于生命和存活是需要的，并且它由一起构成感觉系统的专门细胞检测鱼感觉系统包括能够检测机械和化学刺激的专门器官。特别地，味蕾是位于陆生脊椎动物的舌头上的小器官，其在味觉方面起作用。在鱼中，味蕾出现在嘴唇，侧腹，和一些物种的尾部（尾部）翅片和其他鱼类受体细胞的杠铃上。已经检测到不同类别的离子通道，与哺乳动物中一样，可能参与化学味觉信号的检测和/或转导。然而，由于这些离子通道中的一些参与了额外的感觉形态的检测，可以假设味细胞感知除了对味觉特异性的刺激之外的刺激这个迷你评论总结了目前关于瞬态受体电位（TRP）和酸感（ASIC）离子通道在硬骨鱼，特别是成年斑马鱼的味蕾中的存在的知识到目前为止，已经在感觉细胞中发现ASIC4，TRPC2，TRPA1，TRPV1和TRPV4离子通道，而在提供味蕾的神经中检测到ASIC2
