Scientists may have overlooked a hidden Alzheimer's culprit for decades

ScienceDaily reports that for decades, scientists have focused on amyloid beta as a major culprit behind Alzheimer’s disease, spending billions of dollars developing treatments that have often delivered disappointing results.

Now, researchers at UC Santa Cruz are drawing attention to a largely overlooked peptide called P3 that could also play a role in the disease. Previously believed to be harmless, P3 can form harmful-looking protein clumps even faster than amyloid beta and may also damage brain cells.

This science story centres on the United States. Names and organisations mentioned in the coverage include Alzheimer and UC Santa Cruz.
