NO synthase expression. (A) Representative immunofluorescent images (630× magnification) of RBCs isolated from prediabetic patients stained for RBC-NOS at baseline (T0) and at 180 min after an oral glucose load. (B) Quantitative analysis of RBC-NOS. Data are expressed as the mean of fluorescent intensity (AFU) ± SD subtracted of the negative control value (at least three fields were analyzed). 𝑛 = 13; * p < 0.05.
