The Claim

In aged female 3xTg mice, 7 days of istradefylline treatment is associated with a 52% reduction in cortical PRMT4 protein levels and a 50% reduction in ADMA, restoring both to levels observed in healthy aged C57BL/6 mice, suggesting that A2A receptor blockade may normalize the PRMT4-ADMA pathway linked to nitric oxide dysregulation in Alzheimer’s disease.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In aged female 3xTg mice, 7 days of istradefylline treatment reduces cortical PRMT4 protein levels by 52% and ADMA levels by 50%, returning both to levels seen in healthy aged C57BL/6 mice.

See the scientific wording

In aged female 3xTg mice, 7 days of istradefylline treatment was associated with a 52% reduction in cortical PRMT4 protein levels and a 50% reduction in ADMA, restoring both to levels seen in healthy aged C57BL/6 mice, suggesting that A2A receptor blockade may normalize the PRMT4-ADMA pathway linked to nitric oxide dysregulation in Alzheimer’s disease.

Why this might work

A drug blocks a receptor in the brain that is overactive in Alzheimer’s-like disease. This causes a methylating enzyme to decrease, which in turn lowers a molecule that blocks nitric oxide production. With more nitric oxide available, blood vessels in the brain widen, improving blood flow and reducing damage from protein buildup.

What the research says

1 study
  1. Study: Blockade of A2AR improved brain perfusion and cognitive function in a mouse model of Alzheimer’s disease

    In older female mice with Alzheimer’s-like symptoms, a drug called istradefylline helped fix two broken molecules (PRMT4 and ADMA) that were clogging blood vessels in the brain, bringing them back to healthy levels.
