The paper presents an approach for overcoming modeling problems of typical life science applications with partly unknown mechanisms and lacking quantitative data: A model family of reaction-diffusion equations is built up on a mesoscopic scale and uses classes of feasible functions for reaction and taxis terms. The classes are found by translating biological knowledge into mathematical conditions and the analysis of the models further constrains the classes. Numerical simulations allow comparing single models out of the model family with available qualitative information on the solutions from observations. The method provides insight into a hierarchical order of the mechanisms. The method is applied to the clinics for liver inflammation such as metabolic dysfunction-associated steatohepatitis or viral hepatitis where reasons for the chronification of disease are still unclear and time- and space-dependent data is unavailable.
本文提出了一种克服典型生命科学应用中建模问题的方法,这些应用具有部分未知的机制和缺乏定量数据:建立了一个基于介观尺度的反应扩散方程模型族,并使用了可行的反应和趋化性项的函数类。这些类是通过将生物学知识转化为数学条件来找到的,而对模型的分析进一步限制了这些类。数值模拟允许将模型族中的单个模型与观察到的可用定性信息进行比较。该方法提供了对机制的层次顺序的深入了解。该方法已应用于肝脏炎症的临床,如代谢功能障碍相关脂肪性肝炎或病毒性肝炎,其中疾病慢性化的原因尚不清楚,并且没有时间和空间相关的数据。
