norepinephrine transporter (NET)
The norepinephrine transporter (NET) is a protein found in nerve cells that helps regulate levels of norepinephrine, a chemical messenger involved in alertness, focus, and the body's stress response. NET works by removing norepinephrine from the space between nerve cells (the synapse) after it has transmitted its signal. This process ensures that signals are precise and controlled. Medications targeting NET can influence mood and attention, making it relevant for treating conditions like depression and ADHD. In essence, NET acts as a regulatory gatekeeper, maintaining balance in norepinephrine signaling in the nervous system.
