Tag: Telomere Transfer

Scientists have found that when T cells are activated by antigen-presenting cells, the activating cells donate chunks of their telomeres to the T cells, preventing senescence [1]. Imperfect protection Telomeres are sequences of TTAGGG repeats at the ends of our chromosomes that protect their integrity. Because of the way in which our somatic cells copy...
An international collective of scientists has discovered a new cellular process: telomere transfer from antigen-presenting cells to T cells that boosts the latter's lifespan and proliferative potential [1]. Why We Age: Telomere AttritionTelomeres are DNA regions located at the ends of a chromosome. Their normal length is 8-10 thousand base pairs, yet they consist of...
