Abstract

C‐reactive protein (CRP) and growth differentiation factor 15 (GDF15) are important markers of inflammation associated with several aging‐related morbidities. DNA methylation (DNAm) measures of CRP and GDF15 may provide stable epigenetic measures of chronic exposure to inflammation and could therefore be robustly predictive of inflammation‐related brain aging and neurodegeneration.

Research summary

The paper investigates the relationship between DNA methylation signatures of CRP and GDF15 and brain volume loss, which is associated with aging-related neurodegeneration. While it touches on inflammation and its potential role in brain aging, the focus is more on biomarkers and prediction rather than addressing the root causes of aging or proposing interventions for lifespan extension. Thus, it contributes solid research but has limited impact on the broader field of longevity research.
