What are filopodia?
What are filopodia? Filopodia (singular filopodium) are thin membrane protrusions that act as antennae for a cell to probe the surrounding environment [1][2][3]. Nonprotruding filopodia are mechanistically related to microspikes [4]. Filopodia are commonly [...]
What is the first step in filopodium formation?
What is the first step in filopodium formation? Actin nucleation initiates filopodium formation The first step in the formation of a filopodium is the nucleation of actin filaments from G-actin monomers. This is facilitated [...]
How does cross-linking of actin filaments aid in filopodia extension?
How does cross-linking of actin filaments aid in filopodia extension? Once nucleation has taken place, actin filaments begin to extend. This process is primarily facilitated by members of the formin family of proteins, however [...]
How do filopodia pull on a substrate?
How do filopodia pull on a substrate? Although a reterograde motion of actin filaments is intrinsic in the formation of filopodia, the forces generated by actin treadmilling are too weak to facilitate the “pulling” [...]
How do filopodia move dynamically?
What causes filopodia retraction and collapse? Binding of filopodia to certain ligands or substratum may hinder filament assembly, thereby leading to changes that promote retraction, collapse or growth cone turning [1][2]. For example, substrate [...]
How do filopodia attach to the surrounding substrate?
How do filopodia attach to the surrounding substrate? A diverse array of cellular responses can result when a filopodium makes contact with a ligand or substrate. These responses are dependent on the coupling of [...]
