Twenty years ago, there was still considerable debate of the nature of human ageing, with a variety of competing theories in play. But scientific consensus is forming around the telomere theory of ageing. The essence of this theory is that human ageing is the result of cellular ageing. Every time a cell reproduces, its telomeres (the tips of the chromosomes) shorten. With every shortening of the telomeres, the cell's ability to repair its molecules decreases. It ages. Human ageing is the result of the ageing of the body's trillions of cells. But some of our cells don't age. Sex cells and stem cells can reproduce indefinitely, without ageing, because they create telomerase. Telomerase re-lengthens the telomeres, keeping these cells young.
In The Telomerase Revolution, Dr Michael Fossel, who has been at the forefront of ageing research for decades, provides startling insights into the nature of human ageing and describes how telomerase will soon be used as a powerful therapeutic tool, with the potential to dramatically extend life spans and even reverse ageing.

Description du livre Paperback. Etat : New. Why does growing old lead to so many forms of illness? Recent advances in the study of human cells have revealed that the key to answering this question lies in the telomeres ? the tips of chromosomes ? which shorten every time a cell reproduces. As he explains these insights, Fossel highlights the ability of the enzyme telomerase to re-lengthen the telomeres and discusses its potential as a means of treating age-related diseases such as Alzheimer?s.
