RNA is taking its Toll – Impact of RNA‐specific Toll‐like receptors on health and disease

Abstract

RNA‐sensing Toll‐like receptors (TLRs) are often described as anti‐viral receptors of the innate immune system. However, the past decade has shown that the function and importance of these receptors is far more complex. These receptors were found to be relevant for the detection of various bacterial, archaeal, and eukaryotic microorganisms and facilitate the discrimination between dead and living microbes. The cytokine and interferon response profile that is triggered has the potential to improve the efficacy of next‐generation vaccines and may prevent the development of asthma and allergy. Nevertheless, the ability to recognize foreign RNA comes with a cost as also damaged host cells can release nucleic acids that might induce an inappropriate immune response. Thus, it is not surprising that RNA‐sensing TLRs play a key role in various autoimmune diseases. However, promising new inhibitors and antagonists are on the horizon to improve their treatment.
