Coiling of cellular protrusions around extracellular fibers
Raj Kumar Sadhu, Christian Hernandez-Padilla, Yael Eshed Eisenbach +8
Protrusions at the leading-edge of a cell play an important role in sensing the extracellular cues, during cellular spreading and motility. Recent studies provided indications that…
Modelling cellular spreading and emergence of motility in the presence of curved membrane proteins and active cytoskeleton forces
Raj Kumar Sadhu, Samo Penič, Aleš Iglič +1
Eukaryotic cells adhere to extracellular matrix during the normal development of the organism, forming static adhesion as well as during cell motility. We study this process by con…
Interplay between surface and bending energy helps membrane protrusion formation
Raj Kumar Sadhu, Sakuntala Chatterjee
We consider a one-dimensional elastic membrane, which is pushed by growing filaments. The filaments tend to grow by creating local protrusions in the membrane and this process has…
Actin filaments pushing against a barrier: Comparison between two force generation mechanisms
Raj Kumar Sadhu, Sakuntala Chatterjee
To theoretically understand force generation properties of actin filaments, many models consider growing filaments pushing against a movable obstacle or barrier. In order to grow,…
Actin filaments growing against an elastic membrane: Effect of membrane tension
Raj Kumar Sadhu, Sakuntala Chatterjee
We study the force generation by a set of parallel actin filaments growing against an elastic membrane. The elastic membrane tries to stay flat and any deformation from this flat s…
