A likely cause of Alzheimer’s disease offers a significant finding that offers potential new prevention and treatment opportunities for Australia’s second-leading cause of death.
Ground-breaking new Curtin University-led research has discovered a likely cause of Alzheimer’s disease, in a significant finding that offers potential new prevention and treatment opportunities for Australia’s second-leading cause of death.
The study, published in the prestigious PLOS Biology journal and tested on mouse models, identified that a probable cause of Alzheimer’s disease was the leakage from blood into the brain of fat-carrying particles transporting toxic proteins.
Lead investigator Curtin Health Innovation Research Institute (CHIRI) Director Professor John Mamo said his collaborative group of Australian scientists had identified the probable ‘blood-to-brain pathway’ that can lead to Alzheimer’s disease, the most prevalent form of dementia globally.
“While we previously knew that the hallmark feature of people living with Alzheimer’s disease was the progressive accumulation of toxic protein deposits within the brain called beta-amyloid, researchers did not know where the amyloid originated from, or why it deposited in the brain,” Professor Mamo said.
“Our research shows that these toxic protein deposits that form in the brains of people living with Alzheimer’s disease most likely leak into the brain from fat carrying particles in blood, called lipoproteins.
“This ‘blood-to-brain pathway’ is significant because if we can manage the levels in blood of lipoprotein-amyloid and prevent their leakage into the brain, this opens up potential new treatments to prevent Alzheimer’s disease and slow memory loss.”
Building on previous award-winning research that showed beta-amyloid is made outside the brain with lipoproteins, Professor Mamo’s team tested the ground-breaking ‘blood-to-brain pathway’ by genetically engineering mouse models to produce human amyloid-only liver that make lipoproteins.
“As we predicted, the study found that mouse models producing lipoprotein-amyloid in the liver suffered inflammation in the brain, accelerated brain cell death, and memory loss,” Professor Mamo said.
“While further studies are now needed, this finding shows the abundance of these toxic protein deposits in the blood could potentially be addressed through a person’s diet and some drugs that could specifically target lipoprotein amyloid, therefore reducing their risk or slowing the progression of Alzheimer’s disease.”
Alzheimer’s WA Chairman Adjunct Professor Warren Harding said the findings may have a significant global impact for the millions of people living with Alzheimer’s disease.
“Having universities like Curtin working with the pharmaceutical industry is important if we are to tackle this devastating disease,” Mr. Harding said.
“In Australia, approximately 250 people are diagnosed with dementia daily, adding to the staggering half a million Australians who are already living with dementia. Without significant medical advances like the breakthrough Professor Mamo’s team has made, it is estimated that the number of Australians living with dementia will exceed one million by 2058. This has a significant impact on families, carers and communities.”
Professor Mamo and his research team’s previous research in this area was awarded the NHMRC-Marshall and Warren Award for the most innovative and potentially transformative research.
Currently, the team is conducting a clinical trial, the Probucol in Alzheimer’s-clinical trial, which is based on previous findings that a historic cardiovascular agent lowers lipoprotein-amyloid production and supports cognitive performance in mice.

No help at all. What kinds of foods do these lipoproteins come from?
Steak, potatoes and beeh (Aussie beer)
“No help at all.”
That’s why I skipped reading the article. I figured another Freeper would do it for me. Thanks
or more likely
“treatments could be available within 5 years...”

Meat, of course! It’s been a while, but as I understand it a lipoprotein carries fat molecules. Fat is not water soluble so it needs to be encapsulated and transported inside a molecule that is water soluble. It is interesting that a molecule that large can cross the blood brain barrier but I’m no expert.
I am in no position to dispute the theory but wonder how much of this is tainted by politics like so much science these days. Meaning, move to scare societies away from animal proteins.
I’ve been told that as long as I stick to my diet of pizza, ice cream, and beer, all will be well.
Is this good news or bad news for Joe Biden, I wonder?

There you have, it soon to be at local CVS and Walgreens for a low, low price of $36.95 in the 7 day size and $61 for the 14 day supply. Use the above promo code to get the 1 month supply for only $110
Well if you were going by what Freepers post, you wouldn't have even needed to click on this thread as you would already know Vitamin D cures Alzheimer's...
as well as everything else.
Vitamin D is all you need.
I’ve been told that as long as I stick to my diet of pizza, ice cream, and beer, all will be well.
I think that’s correct. Maybe add a lemon or orange occasionally.
Good question, of course. I didn't see any mention of a food-to-brain path taken by the offending molecule from your sandwich; OR instead, whether the molecule forms from an interaction with something else you've eaten around the same time, or . . .
I have come across such a “potential” groundbreaking medical news many times since I learnt English. But what could not be treated thirty years ago are still not treated
and K2...
Don’t you worry they will have a Vaccine for that.
I think it’s probably more related to how your body might be predisposed to process your food. Two people can eat the same stuff—one gets AD, the other just gets old.
Can’t they suck it out?
...probably already working on a vaccine
