Marijuana Compounds Show Promise In Protecting Brain Cells From Alzheimer's

(Forbes) Some potentially good news about cannabis compounds is wafting from the Salk Institute labs in San Diego. Researchers discovered that the main psychoactive compound in marijuana—tetrahydrocannabinol (THC)—and a few other active compounds remove amyloid beta proteins from lab-grown neurons. Amyloid is the toxic protein known to accumulate in the brains of Alzheimer’s patients. The compounds also significantly reduced cellular inflammation, an underlying factor in the disease’s progression…
“Although other studies have offered evidence that cannabinoids might be neuroprotective against the symptoms of Alzheimer’s, we believe our study is the first to demonstrate that cannabinoids affect both inflammation and amyloid beta accumulation in nerve cells,” said Professor David Schubert, senior author of the study, in a Salk Institute press release.
The brain produces its own cannabis-like molecules, endocannabinoids, which play a signaling role between cells, but also seem to protect nerve cells from inflammatory amyloid damage. THC in cannabis activates the same receptors as the body’s endocannabinoids.
