Acidified Exos^Lamp2b-HuR regulate M1/M2 polarization.

(a, b) Flow cytometry analysis (a) and quantification (b) of the effects of indicated exosomes on the RAW264.7 M1 polarization induced by LPS. Representative image of three biological replicates. (c-d) qPCR analysis of miR-155 (c) and M1 marker genes (d) in RAW264.7 cells treated as above. U6 and β-actin served as internal controls, respectively. Data are expressed as mean±SEM of three different experiments. *, p$<$ 0.05.
