Gene therapy may be a promising approach for treatment of brain ischemia. We and others previously demonstrated that increased activity of matrix metalloproteinases (MMPs) contributes to the tissue damage that results from ischemic injury. The proteolysis of MMPs is tightly controlled by tissue inhibitors of MMPs (TIMPs). In this study, we examined whether adenoviral-mediated gene transfer of TIMP-1 and TIMP-2 could protect against neuronal damage induced by global cerebral ischemia in mice. An adenovirus expressing TIMP-1 or TIMP-2 (AdTIMP-1 or AdTIMP-2) or a control adenovirus (RAd60) or vehicle was injected into the striatum 3 days before transient global cerebral ischemia. The extent of neuronal damage was quantified 3 days post-ischemia. There was no significant difference in the extent of neuronal damage in vehicle as compared to RAd60-treated mice. In contrast, neuronal damage was reduced, by approximately 50%, after gene transfer of AdTIMP-1 (P
