Mystery of the Internal Vibration

Entry for December 09, 2007


I’ve written about Alzheimer’s in this blog in the past and it’s my belief that it can be caused by low levels of zinc. Low zinc levels can cause low magnesium and this will create other reactions in a weakened body that could eventually lead to Alzheimer’s. This guy talks about an enzyme called “MMP-9” that has the natural ability to attack the plaque found in Alzheimer’s. Turns out that they think this specific enzyme requires zinc to work properly. Thus a zinc deficiency would cause the buildup of plaque. Here’s an article that seems to support my theory.

Plaque and the Brain

Dr. Jin-Moo Lee, Assistant Professor of Neurology at Washington University School of Medicine in St. Louis has shown that another enzyme called matrix metalloprotease-9 (MMP-9) also degrades beta amyloid. Dr. Lee found that MMP-9 is able to break down the fibrils that make up the plaques found in Alzheimer’s. MMP-9 and other enzymes break down a free-floating kind of beta amyloid that hasn’t formed into plaques. But in Dr. Lee’s lab, the other enzymes didn’t seem to degrade fibrils the way MMP-9 did. These results suggest that MMP-9, already found in the body, may be helpful in clearing plaques from the brain.
 
It’s also not clear whether drugs designed to increase or decrease levels of MMP-9 could stop brain degeneration and dementia, or what any side effects would be. One possibility for therapy stems from the fact that MMP-9, like many other enzymes, requires the presence of zinc to work. So in theory, reducing the amount of zinc in the body via chelation therapy might inactivate MMP-9 and reduce damage to blood vessel walls. It’s unclear what this might do to the beta amyloid plaques in other areas of the brain, though, and there could be severe side effects. “Removing zinc would likely be detrimental to other systems,” says Dr. Lee.
 
The connection of MMP-9 to both Alzheimer’s and CAA is intriguing, but still murky. More research is needed before any treatments can be developed. “I think we are far from therapies at this point,” Dr. Lee says. “One must remember that at this level of research, we are trying to understand molecular mechanisms, and we are somewhat removed from therapies. However, our goal is to identify potential targets for the development of therapies. It’s too early to say whether MMP-9 will provide us with viable targets, but therapies to ameliorate disease are always on our minds.”
