RNA-seq analysis of human antigen-specific type 1 regulatory T cells (Tr1)

Co-culture of human CD4+ T cells with allogeneeic tolerogenic dendritic cells (DC-10) results in a cell product, called T-allo10, enriched with alloantigen-specific type 1 regulatory T cells (Tr1 cells). CD49b+LAG3+ Tr1 cells and CD49b-LAG3- non-Tr1 cells (DN) were sorted from total T-allo10 cells, and their transcriptomes compared to parental CD4+ T cells, as well as to and control CD49b-LAG3- effector T cells (Teff) sorted from T-allo cells, which were made equivalently to T-allo10 except with using mature dendirtic cells instead of DC-10. Overall design: Tr1 cells compared to all not-Tr1 cells (DN, CD4, Teff)
