The part I found very interesting was when they talked about plaques. Here are a couple of excerpts from the article.
Alzheimer’s disease is characterized by two main elements - the sticky plaques that form outside the brain cells, and tangles of another protein, tau, that twist around the inside of the cells. Both are thought to play a role in the progression of the disease.
The plaques and oligomers are originally formed from a protein found in the body. This amyloid protein breaks down naturally throughout our lives.
Tanzi and others suspect that as the body ages, too many of these protein clumps create a damaging buildup in the brain. They also may trigger the creation of tau tangles that further gum up the brain’s signaling system.
The brain may try to remove the offending oligomers by forming plaques. Tanzi goes so far as to call the much-vilified plaques as “brain pearls”. He says that just as an oyster creates a pearl around a grain of sand to protect itself, plaques may serve as traps for the oligomers that are attacking the brain.
Researchers have found that some people who never had dementia nevertheless have brains inundated with plaques. It may be, they theorize, that their brains are exceptionally good at converting the offending “sand” into “pearls”.
I find the above article interesting, because some time ago I saved the below excerpts to refer to and they seem to me to be related. Am I way off base here?
Changes in normal appearing white matter in multiple sclerosis are characteristic of neuroprotective mechanisms against hypoxic insult. I have been supposing for a while that the fibrin/scars/lesions are a protective mechanism more than a "normal" scarring - a protection from further injury, rather than a reaction to an injury. http://tinyurl.com/mark-abstract.
Some time back, Marcstck (Marc) wrote:
Rusty Bromely, the COO of The Myelin Repair Foundation, was open to the notion of CCSVI. Rusty had an interesting take on the matter of iron deposition, saying that he didn't think it was being deposited by the reflux of blood itself. He believed that if CCSVI was indeed responsible for the iron deposition being found in MS brains, it was because the reflux of deoxygenated blood was leading to the death of oligodendrocytes, which in turn were releasing iron into the brain. Needless to say, I was blown away by the fact that he was so well-versed in the theory that he could make that distinction.
How does Multiple Sclerosis do it’s Damage? http://www.mult-sclerosis.org/howms.html
This article said “Oligodendrocyes belong to a larger grouping of maintenance cells called glial cells. Their importance has recently become better understood and, as more and more is discovered about MS, the more central oligodendrocytes, or more accurately their death, has become. In some ways, it is fair to say that multiple sclerosis is a disease of oligodendrocytes.”
So if we put the two statements together, Rusty’s & the article mentioned above, we get:
“Oligodendrocyes belong to a larger grouping of maintenance cells called glial cells. Their importance has recently become better understood and, as more and more is discovered about MS, the more central oligodendrocytes, or more accurately their death, has become, because, the reflux of deoxygenated blood in the CCSVI protocol leads to the death of oligodendrocytes, which in turn releases iron into the brain!!!!!!!!!”
So anyway which comes first, the egg or the chicken…..are plaques the villains or the pearls, lol.
