Intermediate filaments and cellular mechanics

Abstract

Intermediate filaments (IFs) are one of the three types of cytoskeletal polymers that resist tensile and compressive forces in cells. They crosslink each other as well as with actin filaments and microtubules by proteins, which include desmin, filamin C, plectin, and lamin (A/C). Mutations in these proteins can lead to a wide range of pathologies, some of which exhibit mechanical failure of the skin, skeletal, or heart muscle.

Keywords: cellular mechanics; desmin; filamin C; intermediate filaments; lamin (A/C); plectin.
