Using advanced molecular imaging in drug discovery


To bring new medicines to patients faster and more effectively, 澳门第一赌城在线娱乐一直在寻找方法来提高澳门第一赌城在线娱乐对澳门第一赌城在线娱乐想要治疗的疾病的理解. 利用先进的分子成像技术——最近由质谱技术推动——澳门第一赌城在线娱乐的科学家能够深入和详细地探测和分析组织样本,这在以前是不可能的. By harnessing the powers of artificial intelligence (AI) and machine learning, the full molecular complexity is now becoming decipherable, 先进的成像技术已经揭示了一些有可能改变未来药物发现和开发的见解.


What is molecular imaging?

分子成像是一种先进的成像形式,它增强了澳门第一赌城在线娱乐对药物化合物在细胞水平上对人体组织的影响的理解. 澳门第一赌城在线娱乐的分子成像技术使澳门第一赌城在线娱乐能够探测组织样本-无论是来自患者活检, animal models or advanced cell cultures – in unprecedented depth.

质谱成像(MSI)作为一种强大的分子成像类型脱颖而出, 让澳门第一赌城在线娱乐更好地了解人体的分子复杂性以及候选药物在患者体内的作用. Using this technology, we are able to measure the individual masses of molecules – whether peptides, proteins, lipids, 内源性代谢物或药物分子-使用质谱仪并同时可视化其空间分布. 从MSI中获得的知识为了解组织微环境中这些分子的相互关系提供了重要线索,并使澳门第一赌城在线娱乐能够更好地评估药物的安全性和有效性.


As a measurement tool, mass spectrometry has reached unprecedented levels of power, precision and versatility. 它的应用范围非常广泛:从海洋到手术室再到火星任务. 现在,它正在帮助澳门第一赌城在线娱乐了解健康和疾病中人体组织的全部分子复杂性.

Mass spectrometry is not new and has long been used in many areas of research and development; it relies on the process of ionisation - turning tissue samples into gaseous form. MSI之所以与众不同,是因为组织样品在电离前没有均匀(混合). Instead, the tissue is snap-frozen and ionised directly from its intact surface, so that each molecule’s original position is known. 整个样品一次扫描几微米,提供丰富的数字信息. From this, we can generate vast datasets from healthy, 患病和药物处理的组织样本,并使用人工智能和机器学习技术来发现模式, connections and relationships, turning information into insights and insights into knowledge.

澳门第一赌城在线娱乐也在不断努力改进澳门第一赌城在线娱乐的分子成像技术和方法, including how we prepare and analyse our biological samples. 澳门第一赌城在线娱乐最近开发了新的样品处理协议,可兼容各种成像技术, allowing the same samples to be analysed across platforms. As a result, 澳门第一赌城在线娱乐现在可以整合这些发现,创造出前所未有的复杂生物学观点,并在每个组织样本中揭示更深入的见解.1


Creating a ‘Google Earth’ view on a molecular scale

当今先进的分子成像技术,特别是微星成像技术,使澳门第一赌城在线娱乐的科学家能够创建详细的分子图谱. 就像谷歌地球一样,它可以将地球的卫星视图缩小到单个街道和建筑物的3D视图, 澳门第一赌城在线娱乐的分子成像程序和能力使澳门第一赌城在线娱乐能够从微观到宏观放大和缩小组织. 以这种方式观察样本可以揭示可操作的见解,否则这些见解可能会被组织的生物复杂性所掩盖.

Every molecule we detect has its own map, pieced together by tens of thousands of images from different perspectives. We can “see” drug molecules, 疾病生物标志物和组织微环境同时进行,并从基因组和分子的角度到细胞的角度检查图像, tissue, organ and patient level. For example, with this knowledge, we are paving the way for novel therapeutic development by deepening our knowledge of disease mechanisms,2 combining the powers of molecular imaging with multi-omics to advance our understanding of cancer biology,3,4 评估可能有助于心脏保护的新分子——限制由心脏病发作引起的细胞损伤.5
