    摘要:

    Brain derived neurotrophic factor (BDNF) has been shown to ameliorate recovery after intracerebral hemorrhage (ICH). The injured brain tissue after ICH is surrounded by hematoma formed from hemorrhage. Fibrin is abundant in hematoma, which could be a binding target for BDNF. In this work, we have fused a fibrin-binding domain (FBD) to BDNF (FBD-BDNF), and results demonstrate that FBD-BDNF has specific binding ability to fibrin and is retained in hematoma. Using the rat ICH model induced by bacterial collagenase, injected FBD-BDNF has been concentrated and retained at the hematoma. FBD has facilitated BDNF to exert targeting neuroprotective effect to the injured brain tissue around the hematoma after ICH. FBD-BDNF has significantly reduced the hemotoma volume, reduced tissue loss, promoted neural regeneration, and improved the rat behavioral performance.
