尽管近年来医学成像技术发展迅速, 但在早期的发育阶段, 我们在检测炎症过程或肿瘤以及其他疾病方面的能力仍然有限。然而, 这对于了解肿瘤的生长, 侵袭, 或转移的发展和细胞过程中的炎症性疾病和退化, 心血管和免疫疾病的发展至关重要。虽然传统的成像技术依赖于物理或生理参数, 分子成像使特定分子标记的可视化在体内20。
对于小动物的成像,...

动物模型被广泛应用于科学研究, 许多非侵入性的程序都存在于监测疾病的活动和生命力, 如体重变化的量化或血液、尿液和粪便的分析。但是, 这些只是间接的代理参数, 也受个体的可变性。它们必须经常通过对组织标本的验尸分析来补充, 防止在重复的时间点进行连续观察, 并直接观察生理或病理过程在体内。成熟的小动物成像技术已经出现, 包括横断面成像, 光学成像和内窥镜, 这使这些过程的直接可视化, 也允许重复分析相同的动物1,2,3. 此外, 在同一动物中反复监测各种疾病的可能性可能会减少所需的动物数量, 从动物伦理学的角度来看, 这可能是可取的。
几种不同的光学成像技术存在于体内荧光成像。最初, 共聚焦成像被用来研究表面和地下荧光事件4,5。然而, 最近, 允许进行定量的三维组织评估的层析系统已经开发成6。这是通过开发荧光探针, 在近红外线 (近红外光谱) 频谱发出光, 提供低吸收, 灵敏的探测器, 单色光源7。虽然传统的切削成像技术, 如计算机断层扫描 (CT), 磁共振成像 (MRI), 或超声 (美国), 主要依赖于物理参数和可视化形态学, 光学成像可以提供额外的信息使用内生或外源荧光探针的基础分子过程8。
分子生物学的进步有助于为越来越多的目标提供智能和有针对性的荧光分子探针的生成。例如, 受体介导的摄取和分布在给定的目标区域可以可视化使用 carbocyanine 衍生物标记抗体9。大量可用的抗体, 可被标记为功能作为特定的示踪剂在其他无法进入的身体区域, 提供了前所未有的洞察力分子和细胞的过程中的模型的肿瘤和神经退行性,心血管、免疫学和炎症性疾病7。
在这项研究中, 我们描述了使用荧光介导的层析成像在小鼠结肠炎模型。葡聚糖硫酸钠 (DSS) 诱导结肠炎是一种标准的化学诱导的小鼠肠道炎症模型, 类似炎症性肠病 (IBD)10。这是特别有用的评估先天免疫系统对发展的肠道炎症的贡献11。由于单核和巨噬细胞的招募、活化和浸润是 IBD 发病机制的关键步骤, 因此它们的招募和渗透动力学的可视化是监测的关键, 例如, 影响潜在的治疗性药物在临床前设置12。我们描述了诱导的 DSS 结肠炎, 并演示了利用荧光分子层析成像技术对巨噬细胞浸润肠黏膜的特性, 为单核/巨噬细胞标记 F4/80 的具体可视化13. 此外, 我们还说明了辅助和补充程序, 如抗体标签;实验装置;对所获得的图像进行分析和解释, 与常规读数相关, 如疾病活动指数、流式细胞仪和组织学分析、免疫组织化学。我们讨论这项技术的局限性和与其他成像方式的比较。

fluorescence-mediated tomography for the detection and quantification of macrophage-related murine intestinal inflammation

小鼠疾病模型对科学研究是必不可少的。然而, 许多诊断工具, 如内窥镜或断层成像, 在动物模型中并不经常使用。传统的实验读数通常依赖于宰后和前体分析, 从而防止个体的随访检查, 增加所需的研究动物数量。荧光介导的断层扫描使非侵入性的, 重复的, 定量的, 三维荧光探针的评估。它是高度敏感的, 并允许使用分子制造商, 这使得特定的检测和表征明确的分子目标。特别是, 有针对性的探针代表了一个创新的工具, 分析基因活化和蛋白表达在炎症, 自身免疫疾病, 感染, 血管疾病, 细胞迁移, 肿瘤,等。在这篇文章中, 我们提供了 step-by 的步骤说明, 对这种复杂的成像技术的在体内检测和定性的炎症 (即, F4/80-positive 巨噬细胞浸润) 在广泛使用的小鼠模型肠道炎症。该技术也可用于其他研究领域, 如免疫细胞或干细胞追踪。
