DEPRESSION may not be linked solely to the neurotransmitter serotonin, which is believed to influence mood, according to a study ­produced in the lab of Ethan ­Perlstein, a ­genomics research scholar. In experiments with the antidepressant Zoloft, Perlstein’s team observed a response to Zoloft in yeast cells that could help provide answers to questions about how antidepressants work. Although antidepressants are known to ­regulate serotonin, it is not understood completely how they interact with the body's brain cells and what effect, if any, this activity has on treating depression. The research was published April 18 in the journal PLOS ONE.
