1.   In theory, scientists could develop drugs that bind to the dopamine transporter, which would lock the door to cocaine.

2.   Altropane is a radioactively tagged chemical agent that attaches itself to dopamine transporters, making them readily apparent on brain scans.

3.   Its molecules bind very tightly to molecules in the brain known as dopamine transporters, which regulate the amount of dopamine in certain parts of the brain.

4.   She suggested that the dopamine transporter might be a key player in ADHD, and if so, measuring the amount of the molecules could serve as a test.

5.   The reclaiming is done by a protein called the dopamine transporter, a molecule on the surface of the cell that pumps the dopamine back in.

6.   Two years ago, Caron developed a knockout mouse that was missing the dopamine transporter.

7.   Lerman and colleagues theorize that it leads to a less efficient dopamine transporter, which leaves more dopamine between the brain cells.

8.   Researchers have long known that cocaine attaches to a protein in the brain called a dopamine transporter.

9.   The new work looked into a part of the brain called the striatum to record the density of these dopamine transporters.
