SERT

SERT, or the serotonin transporter, is a protein in nerve cells that helps regulate mood and emotional well-being. It does this by removing the neurotransmitter serotonin from the space between neurons (synapse), controlling its levels. By reabsorbing serotonin, SERT influences how long the mood-boosting signals last. Many antidepressant medications, like SSRIs, target SERT to increase serotonin availability, which can improve symptoms of depression and anxiety. Essentially, SERT plays a key role in maintaining the balance of serotonin in the brain, affecting emotional stability and mental health.
