Introduction to Preventive Geroscience and Its Evolution

Preventive geroscience is a key field that helps us understand aging and disease. The Trans-NIH Geroscience Interest Group, started in 2012, has boosted aging science research across NIH Institutes.

The Birth of Modern Geroscience Research

Geroscience began with discoveries in simple organisms like the nematode worm C. elegans. This was years after the National Institute on Aging was founded. These findings started a deep dive into aging’s basic mechanisms.

Key Pillars of Geroscience Studies

The core of geroscience includes inflammation, immunity, adaptation to stress, epigenetics, metabolism, macromolecular damage, proteostasis, and senescence. It seeks to find ways to improve healthspan and treat age-related conditions by targeting these aging processes.

The Impact on Modern Medicine

Geroscience has greatly advanced our understanding of aging and disease. It found that 3–10% of cells in older adults are senescent, which increases disease risk. This includes diabetes, cardiovascular disease, cancer, and dementia. It aims to change medicine by tackling aging at its roots, enhancing health and life quality.

The Biology Behind Aging and Disease Development

Aging is a complex process where our bodies accumulate damage. This damage leads to less function and makes us more prone to disease and death. Understanding these changes is key to slowing or reversing aging.

Genomic instability is a major driver of aging. It causes cells to stop growing and function properly. This is often due to DNA damage, especially DNA double-strand breaks, which activate repair and cell cycle pathways.

Studies have shown that genomic mutations increase with age. The tongue and bladder are most affected. Long-lived individuals have fewer mutations, showing better DNA repair.

Stress also affects aging. Cellular senescence makes cells lose function but keep producing harmful molecules. Chronic inflammation can make us more susceptible to age-related diseases and frailty.

Interventions like caloric restriction can improve healthspan and reduce disease burden. Research on cellular senescence shows that removing senescent cells can improve function and extend life in aging mice.

Understanding aging’s cellular and molecular changes is vital. Research aims to find genetic, molecular, and cellular factors that influence aging. It also looks at how sensory and motor changes affect aging.

By studying aging and disease, researchers can create better interventions. They aim to reduce oxidative stress and telomere maintenance issues. This could improve health and well-being as we age.

Fundamental Mechanisms of Aging Prevention

Researchers are exploring how to slow down aging. They look into how cells can rejuvenate and how age-related diseases start. This knowledge could lead to ways to delay aging and prevent serious diseases.

Cellular Rejuvenation Processes

Cellular rejuvenation is complex. It involves autophagy, DNA repair, and protein quality control. Autophagy helps clean cells by removing damaged parts. This keeps cells healthy and supports longevity.

Strong DNA repair is also key. It helps fix DNA damage, which can cause aging and disease. RecQ helicase is part of this process.

Molecular Pathways in Age-Related Diseases

Several pathways are linked to age-related diseases. The insulin/IGF-1 signaling, mTOR, and sirtuins pathways are important. They control metabolism, stress response, and inflammation.

These processes are linked to diseases like heart disease, Alzheimer’s, and cancer. Understanding these pathways is crucial for finding new treatments.

Genetic Factors in Aging

Genetics greatly influence aging. Some genes help us live longer, while others increase disease risk. DNA repair, telomere regulation, and stem cell maintenance are key.

Research aims to find out how genetics affect aging. This could lead to personalized treatments and supplements.

“Approximately 105 DNA damage events occur daily in mammalian cells, with indicators of DNA damage present in individuals with age-related diseases such as cardiovascular disease, Alzheimer’s disease, and cancer.”

By studying cellular rejuvenation, disease pathways, and genetics, researchers seek new ways to slow aging. This could lead to a future where people can live healthier, longer lives.

Role of Inflammation and Oxidative Stress in Aging

As we age, chronic inflammation and oxidative stress become major players. They cause cellular damage and organ dysfunction. This can lead to diseases like heart disease, diabetes, and neurodegenerative disorders. Recent studies have uncovered how these factors affect aging. This knowledge helps us find better ways to prevent and manage these issues.

Oxidative stress happens when our body can’t handle reactive oxygen species (ROS). This imbalance damages cells, affecting DNA, proteins, and lipids. Such damage impairs cell function and contributes to age-related diseases. Chronic oxidative stress is linked to many diseases, including heart disease, COPD, cancer, and neurodegenerative disorders.

Inflammation is our body’s defense against injury or infection. But chronic inflammation harms the aging process. It causes tissue damage and increases the risk of age-related diseases. The cycle of inflammation and oxidative stress worsens aging.

Researchers are looking into ways to fight inflammation and oxidative stress. They’re exploring dietary changes, targeted therapies, and lifestyle adjustments. By managing inflammation and reducing oxidative stress, we can slow aging and prevent age-related diseases.

“The integration of inflammation management and oxidative stress reduction strategies is crucial in the field of preventive geroscience, as it offers promising avenues to enhance healthspan and longevity.”
