Medin amyloid may drive arterial aging and disease in the periphery and brain

Aging is a major risk factor for vascular disease. Increased levels of milk fat globule-EGF factor 8 (MFG-E8) are associated with many age-related arterial changes, but the mechanisms remain unclear. We propose that these detrimental effects may result from medin, a fragment of MFG-E8 that forms a highly common vascular amyloid.
