Extension and dynamical phases in random walkers depositing and following chemical trails
Subhashree Subhrasmita Khuntia, Abhishek Chaudhuri, Debasish Chaudhuri
Active walker models have proved to be extremely effective in understanding the evolution of a large class of systems in biology like ant trail formation and pedestrian trails. We…
Deconstructing the role of myosin contractility in force fluctuations within focal adhesions
Debsuvra Ghosh, Subhadip Ghosh, Abhishek Chaudhuri
Force fluctuations exhibited in focal adhesions (FAs) that connect a cell to its extracellular environment, point to the complex role of the underlying machinery that controls cell…
Dynein catch bond as a mediator of codependent bidirectional cellular transport
Palka Puri, Nisha Gupta, Sameep Chandel +5
Intracellular bidirectional transport of cargo on microtubule filaments is achieved by the collective action of oppositely directed dynein and kinesin motors. Experiments have foun…
Catch bond mechanism in Dynein motor driven collective transport
Anil Nair, Sameep Chandel, Mithun K Mitra +2
Recent experiments have demonstrated that dynein motor exhibits catch bonding behaviour, in which the unbinding rate of a single dynein decreases with increasing force, for a certa…
Forced desorption of semiflexible polymers, adsorbed and driven by molecular motors
Abhishek Chaudhuri, Debasish Chaudhuri
We formulate and characterize a model to describe the dynamics of semiflexible polymers in the presence of activity due to motor proteins attached irreversibly to a substrate, and…
