概括

富血小板血 (PRP) 显示出治疗椎间盘退化症 (IDD) 的潜力. PRP疗法可能通过影响mTOR通路而起作用,影响炎症,氧化应激和细胞死亡.

科学领域:

生物医学科学生物医学科学
再生医学是一种再生医学.
整形外科整形外科整形外科

背景情况:

椎间盘退化 (IDD) 是腰部疼痛的一个重要原因.
富血小板血 (PRP) 含有可能促进组织修复的生长因子.
在IDD中PRP的潜在治疗效果背后的机制尚未完全理解.

研究的目的:

评估PRP在椎间盘退化 (IDD) 模型中的疗效.
研究IDD中PRP作用的潜在机制,重点关注Akt/mTOR/p70S6K信号通路.

主要方法:

在使用IL-1β的Sprague-Dawley大鼠和人类细胞核脉细胞中建立了IDD模型.
这些组包括假冒,IDD+酸盐缓冲盐水 (PBS) 和IDD+PRP.
基因和蛋白质表达 (aggrecan,原II,炎症标记物,亡标记物,Akt/mTOR/p70S6K通路) 和氧化应激标记物使用RT-PCR,西斑和测试套件进行了分析.

主要成果:

在IDD模型中,PRP治疗调节了参与细胞外基质降解,炎症,氧化应激和亡的关键分子的表达.
与PBS治疗相比,PRP在基于大鼠和人类细胞的IDD模型中显著降低了酸化Akt,mTOR和p70S6K的表达.
PRP影响了氧化应激 (MDA,SOD,GSH) 和亡 (Bcl-2,分裂-Caspase 3,Bax) 的标志物.

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Intracellular Signaling Affects Focal Adhesions

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.
Some...
