What was done
This paper is a narrative review detailing the molecular and cellular mechanisms of immunosenescence (progressive age-related immune decline) and inflammaging (chronic, sterile, low-grade systemic inflammation). It synthesizes evidence regarding their combined contributions to the pathogenesis of age-related diseases, including cancer, infections, dementia, and neurodegenerative disorders.
What was found
The abstract provides a qualitative conceptual overview and reports no numerical data, effect sizes, or statistical metrics.
Why it matters
It highlights shared molecular and immune-system pathways that link standard aging processes to diverse chronic pathologies, framing these mechanisms as potential overarching therapeutic targets.
Limits
As a non-systematic narrative review, the paper lacks systematic search criteria, risk-of-bias evaluation, and quantitative synthesis. Findings represent mechanism-based reasoning and narrative summaries rather than direct clinical trial evidence.
