基于代理的淋巴结副皮质 T 细胞运输、激活和增殖模拟模型需要细胞运动模型。这样的模型必须能够重现观察到的 T 细胞的随机游走行为,同时容纳大量紧密排列的细胞,并且必须具有计算效率。我们报告了基于 3D 晶格几何形状的运动模型的开发,该模型可以满足这些目标。细胞在相邻晶格位点之间进行离散跳跃,其方向是根据指定的离散概率分布随机确定的,这些概率分布由少量参数定义。结果表明,通常在体内观察到的 T 细胞随机运动的主要特征可以通过适当的模型参数规范来重现。该模型计算效率高,为能够模拟副皮质完整 T 细胞群的模型提供了合适的引擎。
Agent-based simulation modeling of T cell trafficking, activation and proliferation in the lymph node paracortex requires a model for cell motility. Such a model must be able to reproduce the observed random-walk behaviour of T cells, while accommodating large numbers of tightly packed cells, and must be computationally efficient. We report the development of a motility model, based on a 3-D lattice geometry, that meets these objectives. Cells make discrete jumps between neighbouring lattice sites in directions that are randomly determined from specified discrete probability distributions, which are defined by a small number of parameters. It is shown that the main characteristics of the random motion of T cells as typically observed in vivo can be reproduced by suitable specification of model parameters. The model is computationally highly efficient, and provides a suitable engine for a model capable of simulating the full T cell population of the paracortex.
