Geroscience approaches to increase healthspan and slow aging.

Area of Science:

• Gerontology
• Biology of Aging
• Geroscience

Background:

• Historically, aging research focused on lifespan as the primary metric.
• Current geroscience emphasizes functional domains like cardiovascular, skeletal, and metabolic health.
• Understanding age-related tissue decline is crucial for healthspan.

Purpose of the Study:

• To review popular model systems in aging research.
• To discuss their utility in preclinical studies of aging.
• To highlight the importance of functional domains in aging research.

Main Methods:

• Discussion of established and emerging model systems.
• Evaluation of model system strengths and weaknesses.
• Focus on preclinical applications in aging research.

Main Results:

• Model systems vary in their ability to capture complex aging phenotypes.
• No single model perfectly replicates human aging.
• Functional domains offer a more direct measure of age-related decline.

Conclusions:

• Model systems are essential tools for geroscience research.
• Selecting appropriate models is critical for preclinical aging studies.
• Focusing on functional domains enhances our understanding of aging tissues.
