CD8A and rheumatoid arthritis: There are few preceding studies of miRNAs from blood-isolated CD8+ cells in rheumatoid arthritis, but some of the miRNAs found to be DE in this study have previously been associated with RA, e.g. miR-221-3p [35], miR-223-3p [36–38], miR-374b-5p [39] and miR-486-3p [39], however further confirmation is needed.
