What is it about?
In general, telomeres are believed to function within the nucleus. They determine the age of a cell and maintain genome stability. In this article, we described a new role of telomeres, in which telomeres could stimulate inflammation. This stimulation is achieved by a non-coding RNA that transcribed from telomeres, named TERRA. We found TERRA is secreted through exosomes. These TERRA containing exosomes stimulate the production of inflammatory cytokines in the recipient cells.
Why is it important?
Our studies extend the knowledge of telomeres and TERRA, which linked telomere dysfunction with the inflammatory phenotype. It provides new perspectives of inflammation generated during aging and cancer development.
