(A) Human PBMCs (n=9) from healthy donors were treated with DOTAP-miR29a, DOTAP-miR-16, DOTAP alone for 48 hrs. T cell activation was measured by CD69 upregulation on CD3+ T cells by flow cytometry. (B) CD11c+ CD14- human dendritic cells (n=5) were treated with DOTAP-miR29a, DOTAP-miR-16, DOTAP alone for 48 hrs. DC maturation was assessed by mean fluorescence intensity (MFI) of CD40 and CD83 by FACS and (C) Detection of TNF-a and IL-6 in supernatants by ELISA. (D) Human dendritic cells were transfected with Flag TLR8 or Flag EV plasmids with or without Scr or miR-29a or miR-155. Immunoprecipitation was carried out using IgG or Flag Antibody and RNA-IP showing enrichment of only miR-29a in TLR8 transfected cells. Paired t-test was used to compare differences, p<0.05 was considered significant.
