Reelin protein aids brain development and may protect against Alzheimer's and aging-related diseases.

Protein Reelin, which aids brain development, appears to protect against Alzheimer's and aging-related diseases. A trio of recent studies suggest Reelin helps maintain thinking and memory in ailing brains, with lower Reelin levels making neurons more vulnerable. Researchers are exploring the development of drugs to boost or improve Reelin function as a potential means of staving off cognitive decline.
