Scientists propose a “protein aggregation clock” as a new method to assess aging and health by monitoring protein clumps in cells. This concept, if developed into a diagnostic tool, could enable early detection of age-related diseases and assessment of new treatments aimed at reducing protein aggregation. The protein aggregation clock could complement existing genetic-based biological clocks by providing a protein-focused perspective on cellular health and aging.

Professors Dorothee Dormann and Edward Lemke from Johannes Gutenberg University Mainz (JGU) , who also serve as adjunct directors at the Institute of Molecular Biology (IMB) in Mainz, suggest the idea of a “protein aggregation clock” for gauging aging and health. This innovative concept is discussed in their new perspective article published in Nature Cell Biology .
As we age, the DNA and proteins that make up our bodies gradually undergo changes that cause our bodies to no longer work as well as before. This in turn makes us more prone to getting age-related diseases, such as cardiovascular disease , cancer, and Alzheimer’s disease. One important change is that the proteins in our cells can sometimes become misfolded and clump together to form aggregates, so-called amyloids.
Misfolding and aggregation can happen to any protein, but a specific group of proteins known as intr.
