Reversing aging in the blood and immune systems

Urolithin-A is formed naturally in the intestine when the bacteria of the intestinal flora digest a molecule of the ellagitannin family naturally present in pomegranates, nuts and certain berries. Canva - As we age, our bodies face many challenges, including declining immune system function and increased vulnerability to various health problems. A study conducted within the UNIL-CHUV Department of Oncology has recently shed light on these challenges. It unveils a potential solution that could have far-reaching implications for aging individuals. The aging process is often accompanied by a decline in the proper functioning of the hematopoietic system, involved in the creation of new blood cells, and the immune system, in charge of combating aggression. As the years go by, our elders become more vulnerable to infections, blood disorders and even the development of tumors. The study, led by Nicola Vannini , a researcher at the University of Lausanne (UNIL) and member of the Ludwig Institute's Lausanne branch, focused on a key player in the blood system: hematopoietic stem cells (HSCs).
