The invention relates to the selective targeting of specific α2 adrenergic receptor subtypes for facilitating and also restoring standing and walking in a subject affected by spinal cord disorders, in particular spinal cord injury. In particular, the improvement of locomotion by targeting specific receptor subtypes can be achieved by stimulation of the α2c receptor subtype using an α2c specific agonist or by blocking the α2a receptor subtype using α2a antagonists. A combination of an α2c agonist and an α2a antagonist is also provided for a synergistic effect. Alternatively, a large α2 agonist can be used in combination with an α2a antagonist to achieve specific stimulation of the α2c receptor. Pharmaceutical compositions, kit-of-parts and therapeutic systems comprising said agonists/antagonists as active agents are objects of the present invention. A robotic interface and epidural electric stimulation can also be used in combination with the compositions of the invention for restoring voluntary control of locomotion.
本发明涉及选择性靶向特定α2肾上腺素能受体亚型,以促进和恢复受脊髓疾病(尤其是脊髓损伤)影响的患者的站立和行走。特别是,通过使用α2c特异性激动剂刺激α2c受体亚型,或使用α2a拮抗剂阻断α2a受体亚型,可针对特定受体亚型改善运动能力。α2c受体激动剂和α2a受体拮抗剂的组合也可产生协同效应。另外,也可将一种大型 α2 激动剂与 α2a 拮抗剂结合使用,以实现对 α2c 受体的特异性刺激。包含上述激动剂/拮抗剂作为活性剂的药物组合物、部件包和治疗系统是本发明的目的。机器人接口和硬膜外电刺激也可与本发明的组合物结合使用,以恢复对运动的自主控制。
