Methods are provided for inhibiting stenosis following vascular trauma or disease in a mammalian host, comprising administering to the host a therapeutically effective dosage of a therapeutic conjugate containing a vascular smooth muscle binding protein that associates in a specific manner with a cell surface of the vascular smooth muscle cell coupled to a therapeutic agent dosage form that inhibits a cellular activity of the muscle cell. Methods are also provided for the direct and/or targeted delivery of therapeutic agents to vascular smooth muscle cells that cause a dilation and fixation of the vascular lumen by inhibiting smooth muscle cell contraction, thereby constituting a biological stent.
本发明提供了抑制哺乳动物宿主血管创伤或疾病后狭窄的方法,包括向宿主施用治疗有效剂量的治疗共轭物,该共轭物含有血管平滑肌结合蛋白,该蛋白以特定方式与血管平滑肌细胞的细胞表面结合,并与抑制肌肉细胞的细胞活性的治疗剂剂型耦合。还提供了向血管平滑肌细胞直接和/或靶向输送治疗剂的方法,这种方法通过抑制平滑肌细胞收缩,使血管腔扩张和固定,从而构成
生物支架。
