(A) HIV+ non-treated, (B) HIV+ and treated with mEV alone, (C) HIV+ and treated with cmiR mEVs, (D) HIV+ and treated with αmiR mEVs, arrows indicate positive CD68 staining. 20X. Scale bar = 25 µm. (E) CD68 positive cell counts. Group-wise counts were compared with negative binomial regression. LR: likelihood ratio test for negative binomial regression. *P < 0.05, **P < 0.01.
