Trypan blue analysis of activated PBMC viability treated by scalar concentrations of M48U1-HEC (black bars) and M48U1-F127-HPMC (gray bars) at day 7. M48U1-HEC and M48U1-F127-HPMC at M48U1 concentrations with antiretroviral activity are not toxic for PBMCs. Data were expressed as the means (± standard deviations) of viable cells relative to untreated controls (set to 100%) obtained from three independent experiments in duplicate.
