Figure1 (IMAGE) Tokyo Medical and Dental University Caption Study design to create a database of transcripts, called TRAILS (TRAnscriptomic resource of Immune cells using Long-read Sequencing), from different human immune cell subsets and downstream analysis. First, long-read sequencing is performed on immune cell populations to generate full-length isoform sequences. Key attributes of the TRAILS include novelty, repetitive element insertion, cell-type specific expression patterns, translational efficiency, and coding potential. In addition, publicly available short-read RNA sequencing datasets are remapped to the TRAILS to identify disease-linked isoforms through isoform switch analysis, quantitative trait loci (QTL) analysis, and colocalization analysis.
