Figure 4From: Delayed minocycline inhibits ischemia-activated matrix metalloproteinases 2 and 9 after experimental strokeMinocycline concentrations ranging within 0.1 and 1000 μg/ml inhibits the activity of 0.05 ng recombinant human MMP-2 and MMP-9 as compared to the control enzymatic activity. At low concentrations, MMP-9 inhibition is greater than that of MMP-2 (p < 0.05).Back to article page
