中文简介:
我们现在知道,一个单一的人类基因突变可能表现为多种表型中的任何一种,反之亦然,一系列的基因异常可能导致一种单一的疾病表型。这些观察结果得出结论,需要更深入地理解大脑组织在一个空间或时间层面上的变化如何整合并转化为其他变化,最终导致行为和认知或其异常。确定疾病病因学的传统方法——引发症状和体征,创建相似个体的集群并主要根据这些标准定义疾病,并没有在理解产生精神和神经疾病的病理生理机制序列方面产生根本性突破。现在是彻底改变我们对这些问题的认识论方法的时候了。我们现在对大脑的结构和功能了解很多。从基因上,通过功能蛋白的表达,我们对其机制有了更详细的了解。当涉及到大脑微电路、网络和由生理细胞记录、显微解剖和人类神经成像定义的功能专门领域时,我们已经积累了大量关于大脑的知识,但迄今为止,这些知识难以轻易整合和解释。欧洲人脑项目提出了一个医学信息学平台,该平台利用信息技术的现代进步,从超级计算机到分布式和交互式数据库,再结合新的数学和统计学,联合和整合现有和未来的临床和神经科学数据,以实现更具生物基础的,大脑紊乱的机械方法。对药物发现的影响包括更准确的、生物学支持的诊断、确定治疗靶点的新方法、对潜在电子治疗的主要和次要影响的先验分析、对药物试验方法的重新思考以及走向精确和个性化医学的途径。
课程简介: We now know that a single human gene mutation may present with any of multiple phenotypes, and vice versa, that a range of genetic abnormalities may cause a single disease phenotype. These observations lead to the conclusion that a deeper understanding is needed of the way changes at one spatial or temporal level of brain organisation integrate and translate into others, eventually resulting in behaviour and cognition or their abnormalities. The traditional approach to determining disease nosology - eliciting symptoms and signs, creating clusters of like individuals and defining diseases primarily on those criteria has not generated fundamental breakthroughs in understanding sequences of pathophysiological mechanisms that produce the repertoire of psychiatric and neurological diseases. It is time to radically overhaul our epistemological approach to such problems. We now know a great deal about brain structure and function. From genes, through functional protein expression the mechanisms are known in some detail. When it comes to cerebral microcircuits, to networks and to functionally specialised areas defined by physiological cell recording, microanatomy and human neuroimaging we have accumulated a mass of knowledge about the brain that so far defies easy integration and hence interpretation. Europe’s Human Brain Project proposes a medical informatics platform that capitalises on modern advances in information technology, from supercomputers to distributed and interactive databases, allied to new mathematics and statistics, to federate and integrate existing and future clinical and neuroscientific data for a more biologically based, mechanistic approach to brain disorders. The implications for drug discovery range from more accurate, biologically supported diagnostics, new ways of identifying treatment targets, a priori profiling of primary and secondary effects of potential therapies in silico, a rethink about drug trial methodology and a route towards precision and personalised medicine.
