项目摘要

Many practical therapies have been explored for clinical applications to ischemic cerebral infarction; however, the most are still insufficient for treatments for acute stroke. We show here a potential combination therapy in a rat focal ischemic model to improve neurological symptoms as well as reduce infarct volumes at the maximum level. We applied a protein transduction technology using the artificial anti-death FNK protein fused with a protein-transduction-domain peptide (PTD-FNK). When PTD-FNK was administrated at1hr after initiating ischemia followed by the administration of an immunosuppressant FK506 with a 30-min time lag, infarct volumes of the total brain and cortex were markedly reduced to a level of 27% and 14%, respectively. This procedure not only reduced the infarct volume and edema, but also markedly improved neurological symptoms. The therapeutic effect continued at least for 1 week after ischemia. FK506 inhibited the transduction of PTD-FNK in vitro, which explains the requirement of a time lag for the administration of FK506. An additional in vitro experiment showed that PTD-FNK, when administered 30 min before FK506, gave the maximal protective effect through reducing an intracellular calcium concentration. We propose that this combination therapy would give a synergistic protective effect of both drugs, reducing adverse effect of FK506.
许多实用的治疗方法已被探索用于缺血性脑梗死的临床应用,然而,大多数仍然不足以治疗急性脑卒中。我们在这里展示了一种在大鼠局灶性缺血模型中改善神经症状以及最大程度减少梗死体积的潜在联合治疗。我们应用蛋白转导技术,使用人工抗死亡FNK蛋白与蛋白转导结构域肽融合(PTD-FNK)。在缺血后1小时给予PTD-FNK,30分钟后给予免疫抑制剂FK 506,可使全脑和皮质的梗塞体积分别减少27%和14%。该手术不仅减少了梗死体积和水肿,而且明显改善了神经症状。缺血后治疗效果至少持续1周。FK 506在体外抑制PTD-FNK的转导,这解释了FK 506给药需要时间滞后的原因。另一项体外实验表明,在FK 506给药前30分钟给予PTD-FNK,通过降低细胞内钙浓度产生最大保护作用。我们认为,这种联合治疗将提供两种药物的协同保护作用,减少FK 506的不良反应。
