摘要

Summary Aims To study whether adiponectin ( APN ) could improve neurological outcomes in aged mice after ischemic stroke. Methods Adeno‐associated virus carrying APN gene was injected into aged and young adult mice 7 days before transient middle cerebral artery occlusion ( tMCAO ). Atrophic volumes and neurobehavioral deficiencies were determined up to 28 days after tMCAO . Focal angiogenesis was determined based on blood vessel number in the ischemic regions. Results Increased atrophic volume and more sever neurobehavioral deficits were found in the aged mice compared with young adult mice ( P Conclusions Our results demonstrate that APN overexpression reduces ischemic brain injury and improves neurobehavioral function recovery in aged mice than in young mice, suggesting APN is more beneficial in aged animals after ischemic stroke.
