Inflammaging: Chronic Inflammation Drives Aging and Disease
Immunosenescence research, term coined by Franceschi et al. in 2000. · Inflamm-aging: An evolutionary perspective on immunosenescence (Franceschi et al., 2000) (2000)
With age, the immune system enters a chronic, low-grade inflammatory state while simultaneously becoming less effective at fighting pathogens, creating a cycle that accelerates aging and disease.
Core Concepts
The Problem
Persistent inflammation contributes to tissue damage, insulin resistance, cardiovascular disease, and neurodegeneration.
The Claim
Addressing inflammaging through lifestyle and pharmacological means can extend healthspan.
Key Evidence
- •Elevated inflammatory markers like IL-6 and TNF-α are associated with age-related frailty and mortality.
- •Anti-inflammatory interventions in animal models delay age-related decline.
- •Population studies link lower inflammation with longer, healthier lives.
Practical Implication
Monitoring and controlling systemic inflammation may be a key strategy in slowing aging.
Nuance & Limits
Acute inflammation is necessary for repair; the problem is the shift to chronic, unresolved inflammation.
