How an Aging Immune System May Drive Alzheimer's and Parkinson's
Based on: Immunosenescence and Inflammaging as Drivers of Neurodegeneration: Cellular Mechanisms, Neuroimmune Crosstalk, and Therapeutic Implications.
As we age, the immune system gets sloppy and starts running a low-grade inflammation in the background (called inflammaging). This review argues that aging immune cells in the brain lose their protective role and instead fuel diseases like Alzheimer's and Parkinson's. Researchers are exploring senolytics and microbiome therapies to calm this chronic inflammation. It's a reminder that brain aging and immune aging are deeply linked.
Key Insight
This review suggests strategies that lower chronic inflammation may help protect the aging brain.

Muscle Quality Beats Muscle Quantity for Healthy Aging
Looking at adults across the UK, US, and Taiwan, researchers found the muscle-to-fat ratio matters more than raw muscle mass for healthy aging. Inflammation (measured by CRP) rose by 90% between ages 45 and 79, while the growth-related hormone IGF-1 dropped about 20%. Standard BMI-based assessments may hide early muscle decline.
Why Your Mitochondria May Be Driving Aging and Chronic Inflammation
Scientists are zeroing in on mitochondria (the energy factories in your cells) as a main driver of aging, not just a casualty of it. When they break down, they leak signals that trigger chronic, low-grade inflammation and exhaust stem cells. This review highlights NAD+ depletion as a key bottleneck and looks at fixes like NAD+ boosters and mitophagy enhancers.
What Centenarians' Immune Systems Reveal About Escaping Age-Related Disease
People who live past 100 tend to have immune systems that look surprisingly young. This review found they have less chronic inflammation, better cellular cleanup (autophagy), and gut bacteria patterns linked to healthy aging. Those living past 110 often have immune profiles resembling much younger adults.
