Was das Immunsystem von Hundertjährigen über das Entkommen altersbedingter Krankheiten verrät
Basierend auf: The long-lived immune system of centenarians.
Menschen, die älter als 100 Jahre werden, haben oft ein erstaunlich junges Immunsystem. Dieser Review zeigt weniger chronische Entzündungen, bessere zelluläre Reinigung (Autophagie) und Darmbakterien-Muster, die mit gesundem Altern verbunden sind. Über 110-Jährige haben oft Immunprofile wie viel jüngere Erwachsene.
Kernaussage
Diese Forschung legt nahe, dass niedrige Entzündungswerte eine Säule für ein sehr hohes Alter sein könnten.

Why Your Skin Never Forgets Inflammation, Even Years Later
In mice, skin stem cells can hold lifelong "memories" of past inflammation like psoriasis flares. These memories are stored as epigenetic changes. Specific DNA sequences rich in CpG patterns keep the memory accessible through cell divisions. This means once skin has been inflamed, its stem cells stay primed to react faster and stronger to future triggers.
Anti-Inflammatory Foods May Lower Frailty Risk as You Age
Certain blood metabolites tied to fruits, vegetables, nuts, and legumes were linked to lower frailty risk in nearly 10,000 Canadian adults aged 45-85. The protective effect worked partly by reducing inflammation markers. On the flip side, a high omega-6 to omega-3 ratio and processed meat metabolites were tied to higher frailty risk through increased inflammation. The study tracked participants over three years, connecting dietary patterns to measurable metabolic changes.
How Mutant Blood Stem Cells May Quietly Fuel Heart Disease as You Age
As people age, blood stem cells accumulate mutations that cause certain cell lines to expand. This process, called clonal hematopoiesis, is now strongly linked to increased cardiovascular risk in older adults. The mutant blood cells appear to ramp up inflammation, accelerating atherosclerosis and heart failure. This review covers how these rogue clones interact with age-related inflammation and what future therapies might look like.
