The immunosenescence clock: A new method for evaluating biological age and predicting mortality risk

Area of Science:

• Immunology
• Gerontology
• Computational Biology

Background:

• Assessing immune age is crucial for aging interventions.
• Traditional biological age methods have limitations in capturing aging complexity.
• The immune system undergoes significant age-related changes.

Purpose of the Study:

• To propose and detail the concept of an 'immunosenescence clock'.
• To present existing immunosenescence clocks and their functional differences.
• To explore factors influencing immunosenescence and potential interventions.

Main Methods:

• Utilizing immune cell abundance data.
• Analyzing omics data, including transcriptome and proteome.
• Developing biological age and mortality prediction clocks based on immune markers.

Main Results:

• The immunosenescence clock provides a complementary indicator of physiological aging.
• It can be divided into biological age and mortality prediction components.
• The study reviews current immunosenescence clocks and their applications.

Conclusions:

• Immunosenescence clocks offer a novel perspective on age-related changes.
• No single test fully captures biological aging; this approach complements existing methods.
• Understanding immunosenescence mechanisms aids in developing personalized longevity strategies.
