尽管许多研究小组专注于开发新药来治疗森林小组, 但目前只有两个患者可以使用。有迫切的医疗需要找到更有效的治疗方法7 , 因为只有肺 transplantationis 能够延长4-5 年26的生存。转化医学和新药开发的基本前提是能提供一种模仿森林小组特点的动物模型, 而介入研究对临床的成功有预测意义。然而, 现有的肺纤维化动物模型的效用仍然有争议的27</s...

特发性肺纤维化 (IPF) 是慢性肺病, 肺功能逐渐减少, 不幸的是, 在四年的诊断中往往是致命的1。森林小组的主要特点是胞外基质沉积和成纤维细胞增殖, 但尚未完全了解发病机制。最受支持的假说是, 多循环的肺损伤导致肺泡上皮细胞的破坏, 导致间充质细胞周期增殖的改变, 成纤维细胞和肌的夸大积累, 以及增加了矩阵的生成。在人类森林小组或博莱霉素诱导的动物模型中, 失调在纤维化发展中发现了基质金属蛋白酶等过程中所涉及的调解人。无控制的基质生产导致在肺间质和肺泡空间内的胶原沉积不平衡, 模仿异常伤口修复 1, 2.
药物发现和发展的主要障碍之一是可利用的老鼠模型, 模仿人类发病机制和疾病表型。不同的药物已被用来诱导动物模型中的肺纤维化: 辐照损伤, 石棉和二氧化硅的管理, fibrinogenic 细胞因子的管理和博莱霉素3,4;然而, 博莱霉素是最常用的老鼠, 老鼠, 豚鼠, 仓鼠, 兔子5或在大型动物 (非人类灵长类, 马, 狗和反刍动物)6,7。博莱霉素是一种抗生素, 由细菌链霉菌 verticillus8 , 并用作抗癌剂9。肺纤维化是药物的常见副作用, 因此, 它被用于实验动物模型中, 诱发肺纤维化。
博莱霉素诱导的肺纤维化模型, 在博莱霉素管理后 14-21 天发生纤维性病变。在所提出的工作中, 我们采用了新的协议来诱导小鼠肺纤维化的双博莱霉素气管灌注。博莱霉素小鼠模型是非常耗时的, 因为新的药物需要评估已建立的纤维化病变, 并测试, 以区分其抗纤维化的效果与抗炎作用。
对胶原含量、形态测量学和组织学分析的生化测定是基于死后分析, 限制了在同一动物中跟踪疾病发病机制的可能性。虽然这些参数被认为是纤维化评价的金标准, 但它们没有提供任何时间或空间分布的纤维性病变, 并排除了一个方法来调查疾病进展的过程。10
最近, 非侵入性影像技术已被应用于监测小鼠气道重塑、炎症和纤维化进展: 磁共振成像 (MRI), 微计算机断层扫描 (微 CT), 荧光分子层析成像 (裂变材料) 和生物发光 (BLI)11,12,13,14,15,,16,17,18 ,20,21。在博莱霉素挑战22之后, 我们提出一种非侵入性的影像学方法来监测纵向肺纤维化进展的裂变材料和微 CT 在不同的时间点。
许多途径参与了纤维化的建立和发展, 而不多的是已知的。只有对这些过程有更深的了解, 才能转化为可能转移到诊所的更多药物靶点。利用荧光分子层析成像技术对基质金属蛋白酶的活化进行纵向监测, 并通过显微 CT 检测肺实质变化, 可用于今后对治疗的临床反应。

a multimodal imaging approach based on micro-ct and fluorescence molecular tomography for longitudinal assessment of bleomycin-induced lung fibrosis in mice

特发性肺纤维化 (IPF) 是一种致命的肺部疾病的特点是渐进和不可逆转的破坏肺结构, 这导致严重恶化的肺功能和随后死亡的呼吸衰竭。
博莱霉素在实验动物模型中的发病机制已被注射。本文研究了双气管内注射博莱霉素诱导的森林小组样小鼠模型。用于研究肺纤维化的标准组织学评估是侵入性终端程序。这项工作的目的是通过非侵入性成像技术, 如荧光分子层析和微 CT 监测肺纤维化。通过组织学研究证实的这两种技术可以代表一种革命性的功能性方法, 用于对森林小组疾病的严重程度和进展进行实时无创监测。不同方法的融合是进一步了解森林小组疾病的一步, 在这种情况下, 在病理条件下发生的分子事件可以用裂变材料观察到, 随后的解剖变化可以通过微 CT 监测。

肺纤维化病变的自发分辨率观察三周后, 单一的博莱霉素管理和适度的结构变化突出了这个模型的局限性。只有预防性治疗才能执行, 因为狭窄的治疗窗口不代表临床实践17。
在这里, 我们证明, 我们的双博莱霉素气管灌注的协议能够发展长期持久的肺纤维化在小鼠18。实验设计显示在<strong cla...
