Adjunct cerebroprotective therapies are needed to improve recovery. The mammalian target of rapamycin complex 1 (mTORC1) inhibitor rapamycin has shown neuroprotective effects in preclinical stroke models. However, most studies administered rapamycin prior to or during stroke onset, limiting translational relevance. The aim of this study was to determine whether rapamycin administered immediately after recanalization improves infarct size and functional outcome, and whether these effects are associated with changes in cerebral blood flow (CBF) or blood\u2010brain barrier (BBB) integrity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Male Wistar Han rats were subjected to transient middle cerebral artery occlusion (tMCAO) for 90\u2009min.
