Outline of Final Research Achievements |
Because there are 14 subtypes of 5-HT receptor, conventional gene manipulations will require us to pay too much cost for examining all the subtypes. The purpose of this study was to establish a low-cost method for knocking out 5-HT receptor genes by injecting virus vector to the brain of Cas9-expressing mice. The hypothermic effect of serotonin 5-HT1A receptor agonist was attenuated in virus-injected mice. Analysis using DNA mismatch cleavage enzyme confirmed mutation of 5-HT1A receptor gene. However, we failed to obtain electrophysiological evidence using patch clamp methods because the condition of cells was not good.
