I thought that this paper was interesting.

It shows that neurons from people with AD use genetic recombination to produce many different forms of the gene which which codes for the protein (APP) which is converted to Abeta in AD

If confirmed it suggests new treatment options and may also be relevant to other disorders like Parkinson's Disease.

G'day Kiwi,
You may have seen this but I came across it today.

I think this is the abstract
Validation of Plasma Amyloid-β 42/40 for Detecting Alzheimer Disease Amyloid Plaques | Neurology

Thanks Lara.

Interesting, I had not seen it before. I think that not much poor quality work gets accepted in Neurology.

I am grateful that genetics may not determine whether one gets AD or not. I did do dna testing and found I am apoe3/4 and hurried over to a forum on that to learn as much as I could.

Now I am looking into this! “[W]e tracked how amyloid-beta is removed from the [central nervous system (CNS)], showing ~50% is removed across the blood-brain barrier to the blood,” he added. This then led to the discovery that looking at the ratio of amyloid-beta 42 and amyloid-beta 40 could identify whether or not somebody was forming amyloid plaques on their brain.


thank you!
