MMP-2, MMP-3, MMP-9, MMP-13, and MT1-MMP have all been identified in neuronal nuclei and gelatinases (MMP-2 and MMP-9) and MMP-3 have been implicated in the progression of infarct volume and neuronal death in animal models of stroke and ischemic stroke patients [9, 16, 18, 23, 29–33]. Here, MMP2 is linked to ischemic stroke.
