Greg Macpherson, biotechnologist, pharmacist and author of “Harnessing the Nine Hallmarks of Aging,” returns to Late Night Health. He talks about senescent cells, also known as “zombie cells,” which accumulate with age and are associated with many disease states people experience later in life, can add a roadblock to your health now. Senescent cells are defined as cells that, over time, stop dividing but do not die off (which is how they got the nickname “zombie cells”). These cells can begin to release harmful chemicals in the body, damaging normal cells and causing inflammation. Researchers believe that these “zombie cells” have a lot to do with advanced aging and scientists are racing to find solutions that could dramatically help improve one’s healthspan, or how long someone lives without the threat of disease and chronic illnesses. A new study by Japanese scientists claims “zombie cells” can be eliminated by a newly developed vaccine that reportedly creates antibodies that attach themselves to senescent cells, allowing them to be removed by white blood cells. However, Macpherson says the technology to eliminate “zombie cells” already exists in nature (no vaccine required if you get started early).
