Abstract: The serpin plasminogen activator inhibitor-1 (PAI-1), an important risk factor for thrombotic disease can be neutralized by distinct mechanisms, We hypothesized that the combination of two compounds, with PAI-1 neutralizing properties based on different mechanisms, may result in a synergistic effect, Therefore, seven monoclonal antibodies with PAI-1 neutralizing properties were pairwise evaluated for the possible presence of synergistic or antagonistic effects, Out of 21 combinations, three particular combinations, i.e. MA-33H1/MA-33B8, MA-33B8/MA-7D4B7, and MA-7D4B7/MA-33H1 exhibited strong synergistic effects in comparison,vith their properties when evaluated individually, The observed synergism resulted in a maximum enhancement between 2- and 5-fold (P < 0.05, vs, theoretically expected effect calculated based on additive effects), Strikingly, synergism was only observed between monoclonal antibodies directed against different epitopes and with different molecular mechanisms of PAI-1 neutralization, This phenomenon of synergism opens new perspectives in the design of therapeutic or preventive strategies aimed at enhancing endogenous fibrinolysis through modulation of PAI-1 activity.
