极化是单个真核细胞对空间刺激反应的主要步骤,已经吸引了许多理论治疗来补充各种细胞类型的实验研究。虽然这种现象本身是普遍的,但不同细胞类型和不同类型的模型的细节是不同的。大多数模型讨论对称性破缺是如何导致极化的,有些是在抽象的环境中,有些是基于特定的生物化学。在这里,我们比较了实验中常用的细胞(酵母、变形虫、白细胞、角化细胞、成纤维细胞和神经元)对刺激(如化学引诱剂)的极化反应,以及几种典型模型对典型刺激方案的反应。我们发现细胞行为的多样性反映在模型的多样性上,并且一些(但不是所有)模型可以解释刺激的放大、极性的维持、适应性、对新信号的敏感性和鲁棒性。
Polarization, a primary step in the response of an individual eukaryotic cell to a spatial stimulus, has attracted numerous theoretical treatments complementing experimental studies in a variety of cell types. While the phenomenon itself is universal, details differ across cell types, and across classes of models that have been proposed. Most models address how symmetry breaking leads to polarization, some in abstract settings, others based on specific biochemistry. Here, we compare polarization in response to a stimulus (e.g., a chemoattractant) in cells typically used in experiments (yeast, amoebae, leukocytes, keratocytes, fibroblasts, and neurons), and, in parallel, responses of several prototypical models to typical stimulation protocols. We find that the diversity of cell behaviors is reflected by a diversity of models, and that some, but not all models, can account for amplification of stimulus, maintenance of polarity, adaptation, sensitivity to new signals, and robustness.
