We described a non-viral gene transfer in the adult rat brain, using the cationic polymer, polyethylenimine. Micro-injection of sense- or antisense coding sequence of the serotonin transporter (5-HTT) allows its up- and down-expression at the level of serotonin (5-HT) cell bodies and in various projection areas. These regulations of 5-HTT density induced variations in the 5-HT turn-over as well as in the coupling of the 5-HT1A autoreceptors and in sleep-wakefulness rhythms. The data obtained were compared with those elicited by antidepressants or 5-HT releasers. The advantages of this non-viral DNA transfer as compared to other technics are discussed.
