Application of the DREADD technique in biomedical brain research.

Application of the DREADD technique in biomedical brain research. Pharmacol Rep. 2017 Apr;69(2):213-221 Authors: Dobrzanski G, Kossut M Abstract The DREADD (Designer Receptors Exclusively Activated by Designer Drugs) technique is a new chemogenetic approach allowing for selective and remote control of neural activity with a high degree of spatial resolution. Since its discovery in 2007 the DREADD technique was successfully employed into basic research, and together with the optogenetic method provided so far the best tool to influence the activity of the brain circuits and cell populations. The first aim of this review was to concisely describe the technique with regard to such issues like the history of its development, biochemistry as well as modes of the designer receptors delivery and expression. The other aim was to summarize approaches employed for probing of the brain circuits using the DREADD technique and to characterize the current knowledge of the method's application in medical research focusing on two diseases - Parkinson's disease and drug addiction - in which designer receptors were found notably valuable.
