The objective of this study was to examine the interactive effects of exercise and low-level inhibition of GABAA receptors on the recovery of motor function and BDNF expression in the primary motor cortex (M1) of a stroke rat model. Male Sprague-Dawley rats were divided into five groups: sham (SHAM), control (CON), exercise (EX), bicuculline (BIC), and bicuculline plus exercise (BICEX) groups. All rats, except those in the SHAM group, underwent middle cerebral artery occlusion (MCAO) surgery to induce an ischemic stroke. GABAA receptor antagonist, bicuculline (0.25 mg/kg, i.p.), was administered to the BIC and BICEX groups. The EX and BICEX groups exercised on a treadmill (11 m/min for 30 min). Each intervention started 3 days after the MCAO surgery and was carried out every day for 2 weeks. Following the intervention, bilateral M1 BDNF mRNA and protein expression levels were assessed using qRT-PCR and ELISA. Marginal recovery was found in the EX and BIC groups, whereas motor function recovery was enhanced with exercise in the presence of BIC administration specifically in the BICEX group. Furthermore, BDNF protein level in the ipsilateral M1 was significantly higher in the BICEX group than in other groups. This study indicated that exercise combined with low-level inhibition of GABAA receptors after stroke could facilitate the recovery of motor function accompanied by BDNF upregulation in the ipsilateral M1. Therefore, this study provides a novel insight of pharmacological neuromodulation into stroke rehabilitation.

运动加药理神经调节突触抑制可增强缺血性中风后的运动功能恢复。

这项研究的目的是检查运动和低水平抑制GABAA受体对中风大鼠模型原发性运动皮层(M1)运动功能和BDNF表达恢复的相互作用。将雄性Sprague-Dawley大鼠分为五组:假手术(SHAM),对照组(CON),运动(EX),双足(BIC)和双足加运动(BICEX)组。除SHAM组外,所有大鼠均进行了大脑中动脉闭塞(MCAO)手术以诱导缺血性中风。将GABAA受体拮抗剂bicuculline(0.25 mg / kg,ip)给予BIC和BICEX组。EX和BICEX组在跑步机上锻炼(11 m / min,持续30分钟)。每次干预均在MCAO手术后3天开始,每天进行2周。经过干预,使用qRT-PCR和ELISA评估双侧M1 BDNF mRNA和蛋白表达水平。在EX和BIC组中发现了边缘恢复,而在BICEX组中,特别是在BIC给药的情况下,通过运动增强了运动功能恢复。此外,BICEX组同侧M1中的BDNF蛋白水平显着高于其他组。这项研究表明,运动与中风后低水平抑制GABAA受体结合可以促进同侧M1伴有BDNF上调的运动功能的恢复。因此,这项研究为中风康复提供了药理神经调节的新见解。而在BICEX组中,在有BIC的情况下进行运动可增强运动功能的恢复。此外,BICEX组同侧M1中的BDNF蛋白水平显着高于其他组。这项研究表明,运动与中风后低水平抑制GABAA受体结合可以促进同侧M1伴有BDNF上调的运动功能的恢复。因此,这项研究为中风康复提供了药理神经调节的新见解。而在BICEX组中,在有BIC的情况下进行运动可增强运动功能的恢复。此外,BICEX组同侧M1中的BDNF蛋白水平显着高于其他组。这项研究表明,运动与中风后低水平抑制GABAA受体结合可以促进同侧M1伴有BDNF上调的运动功能的恢复。因此,这项研究为中风康复提供了药理神经调节的新见解。这项研究表明,运动与中风后低水平抑制GABAA受体结合可以促进同侧M1伴有BDNF上调的运动功能的恢复。因此,这项研究为中风康复提供了药理神经调节的新见解。这项研究表明,运动与中风后低水平抑制GABAA受体结合可以促进同侧M1伴有BDNF上调的运动功能的恢复。因此,这项研究为中风康复提供了药理神经调节的新见解。
