Aging Biology

The hallmarks of aging proposed by López-Otín and colleagues serve as a comprehensive framework for understanding the biological processes that contribute to aging. This article explores each hallmark, its implications for longevity research, and the current evidence supporting these concepts.

Cellular senescence plays a crucial role in aging and age-related diseases. This article explores the mechanisms behind senescent cells, their impact on health through the senescence-associated secretory phenotype (SASP), and the potential of senolytics as a therapeutic strategy.

Mitochondrial dysfunction is a key factor in the aging process, influencing cellular energy production and health. This article explores the decline of mitochondria, the role of mitophagy, and the importance of NAD+ in promoting longevity.

Mitochondrial dysfunction plays a pivotal role in the aging process, impacting cellular energy production and overall health. This article explores the mechanisms of mitochondrial decline, the importance of mitophagy, and the role of NAD+ in promoting longevity.

Epigenetic clocks are powerful tools that measure biological aging through DNA methylation patterns. This article explores the most prominent clocks, including Horvath, PhenoAge, and GrimAge, and their implications for understanding aging biology.

This article explores the critical roles of proteostasis and autophagy in maintaining cellular health and their implications for aging and longevity. We examine current research and evidence linking these processes to age-related diseases and potential interventions for promoting healthy aging.
