使用内源干细胞动员剂的治疗策略可以为解决各种缺血性疾病提供有效的无细胞疗法。特别是,P物质(SP)通过促进内源性干细胞从骨髓动员到受伤部位而表现出治疗性再生。然而,由于施用的SP肽在体内的半衰期短且快速降解,其治疗效果受到限制。在这里,我们寻求开发与 SP 缀合的高密度脂蛋白(HDL)模拟纳米盘(HDL-SP),以增加 SP 的体内半衰期、骨髓靶向性和治疗糖尿病外周缺血的疗效。 SP 与 HDL 纳米圆盘的结合导致 SP 的离体和体内半衰期分别显着增加约 3215 倍和约 1060 倍。因此,HDL-SP纳米圆盘改善了全身给药后SP在骨髓中的保留,导致干细胞从骨髓有效动员到血液循环中并减少全身炎症。因此,相对于未经纳米圆盘修饰的游离 SP 给药,基于纳米圆盘的 SP 肽递送促进了血管形成、血液灌注恢复,并显着改善了糖尿病后肢缺血模型的肢体挽救。因此,HDL-SP纳米圆盘可以为治疗糖尿病缺血提供一种新策略,并且HDL纳米圆盘修饰可能可用于延长其他不稳定肽的血浆循环。
Therapeutic strategies using endogenous stem cell mobilizer can provide effective cell-free therapy for addressing various ischemic diseases. In particular, substance P (SP) exhibited therapeutic regeneration by facilitating mobilization of endogenous stem cells from bone marrow to the injured sites. However, its therapeutic effect has been limited due to short half-life and rapid degradation of administered SP peptides in vivo. Here we sought to develop high-density lipoprotein (HDL)-mimicking nanodiscs conjugated with SP (HDL-SP) in order to increase the in vivo half-life, bone marrow targeting, and therapeutic efficacy of SP for the treatment of diabetic peripheral ischemia. Conjugation of SP onto HDL nanodisc led to remarkable ~3215- and ~1060-fold increase in the ex vivo and in vivo half-lives of SP, respectively. Accordingly, HDL-SP nanodiscs improved retention of SP in bone marrow after systemic administration, leading to efficient mobilization of stem cells from bone marrow into blood circulation and reduction of systemic inflammation. Consequently, nanodisc based SP peptide delivery promoted blood vessel formation, blood perfusion recovery and markedly improved limb salvage in diabetic hindlimb ischemia model relative to administration of free SP without nanodisc modification. Therefore, HDL-SP nanodisc can provide a novel strategy for the treatment of diabetic ischemia and HDL nanodisc modification could be potentially useful for the extension of plasma circulation of other labile peptides.
