Investigators have functionally linked the Alzheimer’s disease (AD) risk gene SORL1 to apolipoprotein E (ApoE) and clusterin, another apolipoprotein. The work, Tracy Young-Pearse told BioWorld, is part of an attempt to “try to understand different subtypes of Alzheimer’s disease.” It maps some of what Young-Pearse termed the “many molecular roads that lead to Alzheimer’s” – which, in turn, is the first step to setting up roadblocks. Young-Pearse is an associate professor in the Ann Romney Center for Neurologic Diseases at Brigham and Women’s Hospital and Harvard Medical School and co-leader of the Harvard Stem Cell Institute’s Nervous System Diseases Program. She is also the senior author of the paper describing the findings, which appeared online in Cell Reports on Aug. 22, 2023.
