Israeli scientists discover how to reverse cell aging


A team of scientists from the Technion-Israel Institute of Technology say they have found a way to rejuvenate the aging process of the body’s immune system. Prof. Doron Melamed, together with doctoral student Reem Dowery, sought to understand why the elderly population is more susceptible to severe cases of COVID-19 and why the vaccines seem to be less effective and wane faster among this population. The results of their work were published this month in the peer-reviewed journal Blood. The secret begins with B cells, also known as B lymphocytes. These are the cells that produce antibodies against any pathogen that enters the body. They play a key role in protecting people from viruses and diseases. B cells are produced in bone marrow and then travel through the blood to lymph nodes and the spleen, where they wait for pathogens to enter and then attack them. “When you are young, you have young cells, and young cells have a very diverse ability to recognize anything [pathogenic] that comes into your body,” Melamed told The Jerusalem Post.
