Abstract(in English) | There exist many protrusions called filopodias at a neural axon terminal. Filopodial movements are driven by actin polymerization. The Elastic Brownian Ratchet (EBR) model and the Lock, Load, and Fire (LLF) model explain how actin filaments push the cell membrane. This study explores which is a more possible model by comparing the filopodial movements obtained from simulations with those from experimental images. Our simulation results suggest that a single actin filament is insufficient to reproduce the movement of real filopodia for both models. We also show that EBR model is superior to LLF model in reproducibility of experimental data and controllability of dynamic behaviors of growth cones. |
