Project description:We performed a comprehensive miRNA profiling analysis of exosomes by Treponema pallidum-stimulated microarrays. A total of 2×106 macrophages were obtained by THP-1 differentiation and grown in RPMI-1640 containing 10% exosome-free FBS. Exosomes were acquired from macrophage culture supernatants with (n = 7) or without (n = 3) T. pallidum. Briefly, macrophages were washed in PBS twice and further grown in fresh medium for 12 h (n = 2), 24 h (n = 2) and 48 h (n = 3) to collect exosomes. Exosomal miRNA microarray assays were carried out with Agilent Human miRNA (8*60K) array.
