Expression of miR-9-5p, miR-34a-5p, and miR-23a~24-2 cluster in CD8+ naive T cells is regulated by IL-15. Fluorescence-activated cell sorting-sorted naive CD8+CD45RO−CCR7+CD28+ T cells were cultured in the presence of IL-15 (50 ng/ml). Directly after sorting and after 5, 10, and 15 days of culture, expression levels of (A) miR-9-5p, (B) miR-34a-5p, (C) miR-23a-3p, (D) miR-24-3p, (E) miR-27a-3p (all three part of the miR-23a~24-2 cluster), and (F) as a non-IL-15-responsive control, miR-31-5p were assessed by RT-qPCR. Expression levels of the microRNAs (miRNAs) relative to the expression of RNU44 are shown. Significance (*p < 0.05, **p < 0.01, ***p < 0.001) is depicted. N = 6.
