Telomere Length as Presently Measured Does Not Predict Atherosclerosis Risk

Average telomere length is presently measured in white blood cells from a blood sample. Telomeres, the caps of repeating DNA sequences that protect the ends of chromosomes, tend to become shorter on average with age, but also with illness: this is probably largely a reflection of stem cell activity (delivering new cells with longer telomeres) and cell division rates (telomere length reduces with each division) in the immune system, which in turn reflects some of the present state of health and age-related decline. This is a statistical observation, however, and it is has more than enough individual variation to be a pretty terrible measure of aging for any practical use. So it isn’t unexpected to see observations like this one, in which average telomere length … Continue reading Telomere Length as Presently Measured Does Not Predict Atherosclerosis Risk
