The internal clock of immune cells: Is the immune system younger in the morning?
As the immune system ages, it reacts more slowly to pathogens, vaccines become less effective, and the risk of cancer increases. At the same time, the immune system follows a 24-hour rhythm, as the number and activity of ...

Urolithin A nudges aging immune cells toward a youthful profile in 28 days
An international research team focused on aging reports that urolithin A at 1,000 mg per day shifted human immune profiles toward a more naive-like, less exhausted CD8+ state and increased fatty acid oxidation capacity, with ...
Therapies against cellular aging may help treat metabolic diseases
A growing body of evidence implicates cellular senescence—when cells age and permanently stop dividing—as an important contributor to metabolic dysfunction that can lead to obesity, type 2 diabetes, and metabolic syndrome.

Immune cell subset reveals biological age beyond chronological years
Ben-Gurion University of the Negev's Prof. Alon Monsonego had discovered that T helper lymphocytes, a subset of immune cells which regulate immunity, undergo functional changes with age. These changes can indicate the biological ...

Researchers elucidate aging mechanisms and identify a biomarker for aging and overall health status
Aging is a systemic process that affects the entire body. Visible external signs of aging usually correspond to evidence of equivalent aging in the functioning of the internal organs. This indicates that skin cells age in ...

Supercentenarian's biology shows the delicate balance of longevity
Recent studies suggest that the steady rise in life expectancy observed over the past 200 years has now stagnated. Data indicate that a limit has been reached, and that medical and health care advances no longer affect longevity ...
