Green tea catechins, resveratrol, curcumin and metformin reduced amyloid plaque formation in herpes-induced Alzheimer's disease tissue models. (2022)
From the article:
They have tested 21 different compounds in Alzheimer’s-afflicted neural cells in the lab, measuring the compounds’ effect on the growth of sticky beta amyloid plaques. These plaques develop in the brains of people with Alzheimer’s.

The initial screening was done in simpler models, and compounds that had a positive effect were then tested in the 3D neural tissue model. That model is created using a nonreactive silk sponge seeded with human skin cells that, through genetic reprogramming, are converted into neural stem cell progenitors.
Those cells grow and populate the sponge, “which allows for 3D network formation of neurons similar to what you’d see in the human brain,” Cairns says.
The initial screen found five compounds had “really robust prevention of these plaques,” she says. In addition to the green tea compounds and resveratrol, they found curcumin from turmeric, the diabetic medication Metformin, and a compound called citicoline prevented plaques from forming and did not have anti-viral effects.
