Hereditary Alzheimer’s Transmitted Via Bone Marrow Transplants

Alzheimer's disease, traditionally seen as a brain-centric condition, may have systemic origins and can be accelerated through bone marrow transplants from donors with familial Alzheimer's to healthy mice. A new study underscores the disease's potential transmission via cellular therapies and suggests screening donors for Alzheimer's markers to prevent inadvertent disease transfer.

Aging Brain Cells Have Prolonged Death Process

Mature oligodendrocytes, crucial for brain function and myelin production, have an unusually prolonged death process after damage, surviving up to 45 days post-trauma, a stark contrast to the rapid demise of their younger counterparts within 24 hours. This study illuminates a previously unknown pathway of cell longevity, suggesting a potential shift in strategies for treating aging-related damage and neurodegenerative diseases like multiple sclerosis.
