Interconnections between Inflammageing and Immunosenescence during Ageing

Area of Science:

• Gerontology
• Immunology
• Molecular Biology

Background:

• Inflammation is a vital response to injury but chronic inflammation, termed inflammageing, is detrimental to health.
• Successful ageing is associated with low inflammation, while elevated levels increase mortality risk.
• Inflammageing is a marker of biological ageing, multimorbidity, and mortality, not just chronological age.

Purpose of the Study:

• To explore the sources and consequences of inflammageing in the context of immunosenescence.
• To assess the contribution of cellular senescence to age-associated inflammation.
• To highlight potential interventions to reduce inflammageing and improve health in later life.

Main Methods:

• Review of scientific literature on inflammageing, cellular senescence, and immunosenescence.
• Analysis of pro- and anti-inflammatory markers associated with inflammageing.
• Assessment of lifestyle and pharmacological interventions targeting inflammageing.

Main Results:

• Cellular senescence significantly contributes to age-associated inflammation.
• Specific patterns of inflammatory markers characterize inflammageing.
• Ageing of the immune system leads to elevated inflammation.

Conclusions:

• Inflammageing is a complex phenomenon involving cellular senescence and immune system ageing.
• Diet, exercise, and pharmacological interventions show potential for reducing inflammageing.
• Reducing inflammageing may improve health outcomes in older adults.
