资源简介:
It is not known to what extent retrotransposable elements contribute to the development of age-associated diseases. Here we show that during cellular senescence L1s become transcriptionally derepressed and trigger a type-I interferon (IFN-1) response. We propose that RTE activation is an important component of the sterile inflammation that is a hallmark of aging, and that L1 reverse transcriptase is a relevant target for the development of drugs to treat associated disorders.
