Why Does Chronic Inflammation Rise With Age?
There's a low-intensity war inside your body with no endpoint — and it burns hotter after forty
编辑部精选 · 一分钟理解
If you're over forty, check your high-sensitivity CRP (hs-CRP) and IL-6 in your next blood test.
Many people will find these two values elevated — but with no obvious infection and no acute illness.
This isn't a test error. This is inflammaging — the systemic low-grade chronic inflammation that slowly rises with age.
What's distinctive about it: it's simultaneously a product of immunosenescence and the shared underlying mechanism behind elevated risk of cardiovascular disease, diabetes, Alzheimer's disease, and cancer. Understanding it is the starting point for understanding why 'anti-inflammatory' has become the defining keyword in mid-life and older adult health management.
核心要点
01
Inflammaging (chronic low-grade inflammation rising with age) is driven by five overlapping sources: SASP, visceral fat, gut barrier breakdown, CMV chronic activation, and mitochondrial mtDNA leakage. Single interventions are insufficient — multiple pathways must be addressed simultaneously.
02
It's a positive feedback cycle: aging produces inflammation, inflammation accelerates aging. The most effective intervention time is middle age, before the cycle has built full momentum.
03
Senescent cells' SASP is the most important cellular inflammatory source — these 'undead' cells continuously releasing pro-inflammatory factors are the core target for senolytic research.
04
Mitochondrial mtDNA triggers innate immune inflammation through the cGAS-STING pathway — aging cells treating their own organelles as intruders is one of inflammaging's deepest molecular roots. Maintaining mitochondrial function is the foundational approach to slowing this process.
05
CMV seropositivity (over 90% in older Asian adults) is the strongest infectious driver of inflammaging — maintaining immune function is the only means of controlling CMV chronic activation.
06
hs-CRP is the most practical inflammaging monitoring indicator — recommend adding to annual health assessment and tracking trend. Target: below 1 mg/L.
