A PROTEIN CALLED REELIN KEEPS POPPING UP IN BRAINS THAT RESIST AGING AND ALZHEIMER'S

Summary from the TLDR newsletter

A key protein called Reelin appears to protect the brain from Alzheimer's and other diseases of aging. Studies suggest that the protein helps maintain thinking and memory in ailing brains. The research has inspired efforts to develop a drug that boosts Reelin or helps it function better. The discovery of Reelin was aided by the cooperation of about 1,500 members of an extended Colombian family that carries a gene that almost guarantees the development of Alzheimer's in middle age.
