Depressed Mice Just Need a Shot of Gene Therapy in the Brain

According to a new study out in Science Translational Medicine, treating depressed mice with gene therapy in the brain to bolster a protein connected to the neurotransmitter serotonin can make those depressive symptoms dissipate.

Here's the gist: The gene in question creates a protein called p11 that help carry serotonin receptors up to the surface of a brain cell where they can receive signals from other brain cells. Poor serotonin signaling may be one of the major drivers behind depression, a
