A) Plasma levels of NAMPT versus therapy status, as assessed by ELISA (n _Control = 13, n _{Therapy-naïve} = 24, n _ART = 19); B) Total NAMPT protein expression in monocytes of therapy-naïve HIV patients (VL ≥ 4 log copies/ml), normalised to β-actin expression, as assessed by ECL-Western Blot (n_Control = 15, n_{Therapy-naïve} = 28). p-values calculated by nonparametric Mann-Whitney test; n.s.: not significant, ART: antiretroviral therapy.
