Now available nucleotide sequences of neurotransmitter receptor genes enable to apply oligonucleotides targeted to mRNAs of these genes for highly selective inactivation of their expression (antisense-knockdown) and for function determination of single receptor subtype by this experimental approach. The antisense-knockdown may be of special importance in case of receptor families members of which are pharmacologically similar. Advantages of the antisense technology for investigation into the brain neurotransmitter receptor function in regulation of behaviour, are discussed.
目前可获得的神经递质受体基因的核苷酸序列,使得针对这些基因的mRNA的寡核苷酸能够用于高度选择性地使其表达失活(反义敲低),并通过这种实验方法来确定单一受体亚型的功能。在受体家族成员在药理学上相似的情况下,反义敲低可能具有特殊重要性。本文讨论了反义技术在研究大脑神经递质受体功能对行为调节作用方面的优势。
