Alzheimer’s disease (AD) is the most common form of dementia affecting people over the age of 60, yet a detailed understanding of the molecular changes involved in AD remains a significant challenge to modern medicine. The hallmarks of an AD brain include the presence of senile plaques formed by a protein called amyloid-β (Aβ), along with inflammation of the brain. Aβ self-associates to form clumps of protein called “aggregates” which are known to be the primary toxic agents in AD pathology; however, several other proteins have also been implicated in this pathology. One such protein called progranulin (PGRN), which under …
