Effect of lacidipine on the secretion of active and total free MMP-9 by human macrophages
| Additions | Active Free MMP-9 | Total Free MMP-9 |
|---|---|---|
| μM | ng/ml medium ± S.D. | |
| No addition | 2.45 ± 0.01 | 2720 ± 68 |
| Lacidipine (10) | 1.60 ± 0.012-150 | 1968 ± 382-150 |
| Lacidipine (20) | 0.90 ± 0.032-150 | 1760 ± 872-150 |
Human macrophages were incubated has described in Table 1. Then media were collected and the amount of active and total free MMP-9 released by cells was measured by ELISA, as described under Materials and Methods. Data are the mean ± S.D. of two experiments performed in triplicate.
