Exploring the causal relationship between telomere regulation, aging and neurological disorders

Area of Science:

• Neuroscience
• Genetics
• Aging Research

Background:

• Telomere biology is crucial for aging and neurological disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), stroke, and brain tumors.
• Telomere shortening is implicated in neurodegeneration, immune senescence, and cerebrovascular dysfunction.
• Shorter leukocyte telomere length (LTL) correlates with increased stroke risk, poorer AD cognitive outcomes, and MS neuroinflammation, suggesting biomarker potential.

Purpose of the Study:

• To review the causal relationship between telomere biology, aging, and neurological disorders.
• To explore novel therapeutic strategies targeting telomeres for neurological conditions.
• To identify future directions in telomere research for neurodegenerative diseases and brain tumors.

Main Methods:

• Review of existing literature on telomere biology and neurological disorders.
• Analysis of studies investigating telomere length as a biomarker.
• Examination of therapeutic approaches targeting telomere maintenance (e.g., telomerase activators/inhibitors).

Main Results:

• Telomere attrition is associated with neurodegeneration, immune senescence, and cerebrovascular dysfunction.
• Mendelian randomization studies link neurodegenerative diseases with telomere length regulation.
• Telomere dynamics play a role in the pathogenesis of various neurological disorders and brain tumors.

Conclusions:

• Telomere length serves as a potential biomarker for neurological disease progression and severity.
• Targeting telomeres offers promising therapeutic avenues for neuroprotection and brain tumor treatment.
• Further research is needed to refine telomere biomarkers and elucidate mechanistic links to neurodegeneration, balancing therapeutic benefits against oncogenic risks.
