U.S. and Brazilian scientists have discovered that the brain manufactures proteins that act like marijuana at specific receptors in the brain itself. ...
Scientists made their discovery by first extracting several small proteins, called peptides, from the brains of mice and determining their amino acid sequence. The extracted proteins were then compared with another peptide previously known to bind to, but not activate, the receptor (THC) affected by marijuana. Out of the extracted proteins, several not only bound to the brain's THC receptors, but activated them as well.
"The War on Drugs has hit very close to home," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "Last year, scientists found that our skin makes its own marijuana-like substance. Now, we see that our brain has been making proteins that act directly on the marijuana receptors in our head. The next step is for scientists to come up with new medicines that eliminate the nasty side of pot—a better joint, so to speak."
