Paper: Active force maintains the stability of the contractile ring

Stanard Mebwe Pachong and Kristian Müller-Nedebock “Active force maintains the stability of a contractile ring” European Physical Journal E (2017) 40:91 DOI:10.1140/epje/i2017-11581-9 We discuss how motors in the contractile ring bring about its stability, separating the effects of the activity and the networking.

Active systems

Molecular machines are responsible for a variety of non-equilibrium actions. They can make cells themselves move about, and perhaps exhibit fascinating collective motion, and the are responsible, amongst other things, for the transportation of cargo, or play a role in the tightening of the contractile ring during cells division. A range of molecular motors move… Read More »

Dr Ben Loos (Dept of Physiological Sciences at Stellenbosch University) has a long-standing interest in the molecular mechanisms that control cell death susceptibility. His research centres around protein degradative mechanisms and their dynamics, transport and function of mitochondria along tubulin networks and their role in neuronal degeneration and migration.  His research group utilizes in vitro… Read More »

The organisation and dynamics of intracellular structures that maintain a cell’s form, shape, function and viability are rather complex. An emerging central theme which addresses this complexity deals with ATP-driven intracellular transport mechanisms along the tubulin network or the ability of mitochondria to rapidly undergo fission and fusion, and thereby creating a network that is adapted to… Read More »
