“It tells us there are some factors that are protecting their brains and memories against the Alzheimer’s pathology of plaques and tangles. Now we have to find out what those are.”
There are just a few researchers that believe that the plaques are protective. I found some that think that they are there to isolate the toxoplasmosis parasites that can get thru the blood/brain barrier. The apicomplexians can “tunnel” thru cell walls with a special organ in their cytoplasms, and some other microbes get in by tunneling along the myelin sheaths where nerves pathways enter/exit.
edit: Also has been found that one of the basic sugars can open the BB for up to 20 min. IIRC correctly, it was maltose.
Also young blood , possibly stem cells from youngsters is again shown to reduce effects of aging.
“Minami says she has identified some factors in young blood that might be responsible for these benefits, but that she won’t reveal what they are yet. Some of them seem to be crossing into the brain, while others may be acting remotely, elsewhere in the body, she says.”
