It works in the lab, but will it work in our bodies? The normal cellular process, RNA interference, might be exploited therapeutically to fight disease. But a better understanding of RNAi itself, the delivery and specificity of RNA molecules in vivo, and the toxicity and immunological responses is required. Nature’s RNAi Therapy Collection presents primary research, commentary, and news articles on RNAi therapy and features an amazing RNAi animation.
