Abstract

Mechanical deformation of lipid membranes plays important roles in various cellular tasks. Curvature deformation and lateral stretching are two major energy contributions to the mechanical deformation of lipid membranes. In this paper, continuum theories for these two major membrane deformation events were reviewed. Theories based on curvature elasticity and lateral surface tension were introduced. Numerical methods as well as biological applications of the theories were discussed.

摘要

脂质膜的机械变形在各种细胞活动中起着重要作用。曲率变形和横向拉伸是脂质膜机械变形的两个主要能量贡献。本文综述了这两种主要膜变形事件的连续介质理论。介绍了基于曲率弹性和横向表面张力的理论。讨论了这些理论的数值方法以及生物学应用。
