(A,B) Analysis of transcript levels of TNF-α (A) and TGF-β (B) in differentiated THP-1 cells. The quantitative real-time PCR (qPCR) of tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β mRNAs was conducted in THP-1 cells treated for 1 h with ND and PEG liposomes. C = control; ND = non decorated liposomes; PEG = liposomes decorated with PEG (polyethylene glycol). Data in graphs are expressed as means ± SEM of three independent experiments. * p < 0.05, ** p < 0.001 vs. control.
