Supercentenarian Longevity: How Protective Biology

How Can Extreme Aging and Biological Resilience Occur Together?

Maria Branyas Morera lived to 117, making her an exceptionally rare example of human longevity. Researchers used a multiomics approach to examine several layers of her biology, including genomic, epigenetic, metabolic, immune and microbiome features. The analysis identified signs expected in advanced age, but it also found characteristics that may have supported cardiovascular, metabolic and immune resilience.

This apparent contradiction reflects an important principle of geroscience: chronological age does not capture every dimension of biological function. Some molecular measurements may indicate advanced aging while particular pathways, tissues or risk factors remain unusually well preserved. Researchers therefore distinguish exceptional lifespan from healthspan, the period of life spent in relatively good health.

What Can a Multiomics Study Reveal About Longevity?

Genomics examines inherited DNA, epigenomics measures chemical regulation of genes, metabolomics profiles small molecules involved in cellular activity, and microbiome analysis characterizes microbial communities. Studying these layers together can reveal whether potentially protective signals converge across different biological systems.

The approach is valuable because aging is not controlled by one gene, biomarker or organ. However, associations within one extraordinary individual cannot prove cause and effect. Some features may have promoted longevity, while others may simply reflect surviving to an extreme age, lifelong habits, medical care or exposures unique to that person.

Can These Findings Help Other People Live Longer?

The study may help researchers identify biological pathways worth examining in longitudinal cohorts and clinical trials. Comparisons involving supercentenarians, their relatives and people experiencing typical aging could clarify which characteristics predict preserved function rather than merely accompanying extreme survival.

No commercial biological-age test can currently tell an individual exactly how long they will live, and this case does not validate supplements or anti-aging treatments. Established measures such as avoiding tobacco, remaining physically active, receiving preventive care and managing blood pressure, cholesterol and diabetes have much stronger evidence for reducing premature illness and death.
