Targeting senescence mitigates the deleterious effects of midlife obesity on neurovascular function by partially restoring blood–brain barrier integrity and neurovascular coupling

Key Points

This research aims to identify how targetting cellular senescence can improve neurovascular function affected by midlife obesity.
Examined the impact of targeting senescence on blood–brain barrier integrity and neurovascular coupling responses.
Investigated the relationship between senescence, neuroinflammation, and cognitive dysfunction in midlife obesity.
Targeting senescence restored blood–brain barrier integrity.
Improved neurovascular coupling responses observed in subjects with midlife obesity.
Reduced levels of neuroinflammation linked to senescence targeting, indicating potential cognitive protection.

Abstract

senescent cells partially restored BBB integrity, improved NVC responses, and reduced neuroinflammation. Together, these findings identify cellular senescence as a mechanistic driver of midlife obesity-induced cerebrovascular and cognitive dysfunction and provide proof-of-concept that senescence-targeted therapies may preserve brain health in individuals with midlife obesity who are at risk for dementia.
