Double-negative T cell therapy alone or in combination with oral UDCA alleviates primary biliary cholangitis in mice

Methods: The DNT cells incubation with anti-CD3/CD28 antibodies were stimulated with UDCA (60uM) for 48 hours, then transcriptome sequencing studies were performed on DNT cells RNA.Transcriptome sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer's recommendations and sequenced on an Illumina Hiseq platform (Illumina, San Diego, CA). Sequences were aligned to the reference genome with TopHat and processed with Cufflinks, which quantifies each transcript in each sample using reference annotations produced by the University of California Santa Cruz UCSC. Differentially expressed genes with a fold change of >=1.41 and pvalue <= 0.05 between UDCA treated and control DNT cells were submitted to GO and KEGG enrichment analysis, which uses unbiased methods to assess pathway enrichment. Overall design: DNT cells mRNA profiles of control and UDCA stimulated were generated by deep sequencing in duplicate, using Illumina instrument.
