On my desk to read today? These papers on RNAi as a viral defense.
Sabin LR, Zheng Q, Thekkat P, Yang J, Hannon GJ, Gregory BD, Tudor M, Cherry S. Dicer-2 processes diverse viral RNA species. PLoS One. 2013;8(2):e55458. PMID: 23424633; PMCID: PMC3570552
From the abstract: "This study uncovered several novel, heavily targeted features within viral genomes, offering insight into viral replication, viral immune evasion strategies, and the mechanism of antiviral RNAi."
