膜粘附和结构域形成

Membrane adhesion and domain formation

Thomas R. Weikl, Reinhard Lipowsky

摘要:

我们回顾了粘附诱导的生物膜相行为的理论结果。重点是模型中的膜表示为离散的弹性片嵌入粘附分子。我们提出了几种机制,导致在粘附过程中形成的域,并讨论了蒙特卡罗模拟中获得的畴图案的时间依赖性的演变。模拟的图案动力学具有惊人的相似性,在T细胞粘附过程中观察到的图案演变。

英文摘要:

We review theoretical results for the adhesion-induced phase behavior of biomembranes. The focus is on models in which the membranes are represented as discretized elastic sheets with embedded adhesion molecules. We present several mechanism that lead to the formation of domains during adhesion, and discuss the time-dependent evolution of domain patterns obtained in Monte-Carlo simulations. The simulated pattern dynamics has striking similarities to the pattern evolution observed during T cell adhesion.
