As people age, certain cells accumulate in the body known as senescent cells. These cells are essentially ‘old’ cells that no longer function properly and release inflammatory signals. This can lead to chronic inflammation, a common problem in older people that can damage tissues and organs.
Scientists are now searching for reliable markers, also known as biomarkers, to better measure these senescent cells. Biomarkers are measurable biological phenomena that provide clues about processes in the body. Finding good biomarkers can help to precisely determine how senescent cells contribute to age-related inflammation.
It is important that these biomarkers are clear and simple, especially for drug development. This way, new treatments can focus on removing senescent cells and reducing inflammation. Up to now, many of these developments have been investigated mainly in animal studies, but without good biomarkers it is more difficult to test and approve new drugs.
For people who want to age healthily, this research is of great importance. It shows that in the future we may be able to better tackle inflammation in older people by targeting the right cells.
