Actin motility in Listeria

Listeria is a common bacteria that easily parasites cells by going through its cell membrane. It is an outstanding example of motion only by actin monomer polymerization. This video describes a first approach to the operation of actin gel formation and introduces 3 phases of actin gel growth leading to Listeria motility at a steady state.

In this video, Lacroix Noëmie, based on the work of N. D. Marenduzzo et al. and Yuan Lin, explains the basics of Actin-based motility.

Lacroix Noëmie is a student in the Cell Physics Master at the University of Strasbourg, France.
