PROBLEM: Question: Does the rtPA increase MMP-9 activity in serum during ischaemic stroke?
Answer: Thrombolysis applied for IS treatment increases MMP-9 activity in serum, however, rtPA does not facilitate the conversion of pro-MMP-9 into the active form. Our results also suggest the involvement of MMP-3 to the biochemical processes occurring during acute phase of IS.

SOLUTION: yes
