Scientists Uncover Chronic Inflammation Mechanism in Aging and Identify Drug to Reduce It

Advancing the Fight Against Aging

According to НВ — Техно: Researchers have uncovered how so-called “zombie cells” drive persistent inflammation in older adults. An international team from the Sanford Burnham Prebys Medical Discovery Institute, Mayo Clinic, and other institutions discovered a critical link between mitochondria, cellular metabolism, and age-related chronic inflammation.

The study revealed that aging leads to the buildup of senescent cells-cells that no longer divide but remain metabolically active. These cells release molecules that trigger ongoing inflammation. Their mitochondria produce excessive acetyl-CoA, causing changes in histone proteins that open up DNA regions controlling inflammation-related genes.

Implications for Future Therapies

Furthermore, damaged mitochondria release genetic material within the cell, which further activates inflammatory responses. To test this, scientists administered the drug CTPI-2, which inhibits acetyl-CoA synthesis. Trials in mice showed that CTPI-2 markedly reduced inflammation in tissues, improved their function, and extended the animals’ healthy lifespan.

These findings, published on September 14, 2023, offer promising new insights into aging mechanisms and potential strategies to slow the process. Understanding how senescent cells contribute to chronic inflammation may pave the way for innovative treatments targeting age-related diseases such as:

• arthritis
• diabetes
• cardiovascular conditions

This research also highlights the importance of maintaining mitochondrial health as a key factor in promoting wellness during aging. As the global population grows older, such discoveries are vital to improving quality of life in later years.

In light of these recent findings on chronic inflammation and aging, it's intriguing to consider individual cases that exemplify both advanced aging signs and potential longevity mechanisms. For instance, the remarkable story of María Branyas, who at 117 years old, showcases how certain individuals navigate the complexities of aging. Her experience could offer further insights into the biological factors that influence health in later life. To explore her unique journey, visit Branyas' remarkable health and aging.
