Diao F, Ironfield H, Luan H, Diao F, Shropshire WC, Ewer J, Marr E, Potter CJ, Landgraf M, White BH. Plug-and-Play Genetic Access to Drosophila Cell Types using Exchangeable Exon Cassettes. Cell Rep. 2015 Mar 3;10(8):1410-21. PMID: 25732830.
From the abstract: "... we introduce a simple, versatile method for achieving cell-type-specific expression of transgenes ... Our method couples the expression of a transgene to that of a native gene expressed in the cells of interest ... We demonstrate the efficacy of this approach in Drosophila ... We also introduce an exchangeable, MiMIC-like Trojan exon construct that can be targeted to coding introns using the Crispr/Cas system."
