Abstract

Medin is a protein fragment derived from milk fat globule epidermal growth factor VIII (MFG-E8). Medin aggregates are present in the vessel wall of most subjects over 50 years of age. In this narrative review, we focus on the consequences of medin aggregation in relation to the development of dementia. Recent literature revealed medin as biomarker for dementia in CSF, specifically of a vascular subtype. Preclinical work showed that medin is associated with aging-related cerebral vascular dysfunction, vascular stiffening, hypertension, and. vascular amyloid β deposition. These findings position medin as a potential mechanistic link between aging, vascular pathology and dementia.

Research summary

The paper discusses medin as a potential link between vascular pathology and dementia, highlighting its role in aging-related cerebral vascular dysfunction. While it touches on mechanisms related to aging and dementia, it primarily focuses on the association rather than addressing root causes or interventions for aging itself. Thus, it contributes solidly to the understanding of age-related diseases but does not significantly advance the field of longevity research.
