TOR-dependent cerebrovascular aging in Alzheimer's disease

Area of Science:

• Gerontology and Neuroscience
• Vascular Biology
• Molecular Medicine

Background:

• Vascular dysfunction is a hallmark of aging and linked to neurological diseases.
• Mammalian/mechanistic target of rapamycin (mTOR) inhibition extends lifespan and healthspan in mice.
• Understanding aging mechanisms is crucial for treating age-related cognitive decline.

Purpose of the Study:

• To review evidence linking mTOR to age-associated vascular dysfunction.
• To explore mTOR's role in cognitive decline, particularly in Alzheimer's disease.
• To discuss potential therapeutic strategies targeting mTOR.

Main Methods:

• Literature review of existing studies on mTOR, vascular aging, and neurological diseases.
• Analysis of proposed molecular mechanisms.
• Synthesis of current evidence and identification of research gaps.

Main Results:

• mTOR pathway plays a critical role in age-related vascular dysfunction.
• Evidence suggests mTOR contributes to the pathogenesis of Alzheimer's disease.
• mTOR inhibition shows promise in mitigating aging-related vascular and cognitive decline.

Conclusions:

• Targeting the mTOR pathway may offer a novel therapeutic approach for age-related neurological disorders.
• Further research is needed to elucidate the precise mechanisms linking mTOR, vascular health, and cognitive function.
• Interventions aimed at modulating mTOR could potentially improve brain health during aging.
