All immune responses, from intrinsic to adaptive, need to be regulated – if left on indefinitely they will damage the host. The innate immune response is no exception, and a cellular RNA has been identified that binds to a sensor of viral RNA and regulates the production of interferon (IFN).
The TWiVumvirate reviews this years crop of Nobel Prizes, and how cells prevent leakage of mitochondrial double-stranded RNA into the cytoplasm, which would otherwise lead to the production of interferon. <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span><span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span>&lt;span data-mce-type=”bookmark” style=”display: inline-block; width: …
Mitochondria are descended from bacteria that invaded cells 1.5 billion years ago and never left. The mitochondrial genome is like that of bacteria: circular double-stranded DNA, only smaller. And just like the genome of bacteria, RNA can be made from both strands of mitochondrial DNA – which results in the formation of dsRNA. Fortunately there …
