Life at the Leading Edge
Cell migration requires sustained forward movement of the plasma membrane at the cell's front or "leading edge." To date, researchers have uncovered four distinct ways of extending the membrane at the leading edge. In lamellipodia and filopodia, actin polymerization directly pushes the plasma membrane forward, whereas in invadopodia, actin polymerization couples with the extracellular delivery ...
متن کاملRealities at the leading edge of research.
When the Wright brothers set out to invent a flying machine at the end of the nineteenth century, they knew they were facing quite a challenge. Not only was it a daunting task to accomplish powered flight but also to overcome the ideology, morality and sensibility of their time, when most people believed that human flight was neither possible nor natural. Science fiction author Arthur C. Clarke...

Keynote: The Future of Power Electronics and the Impending Challenges to Metrology Thomas Neyer Fellow, High-Voltage Device and Technology Development, Fairchild Semiconductor Power electronics has successfully established its foothold in most domestic, industrial and automotive applications like power supplies, household machines, air conditioners, power generation and transmission units, all ...
متن کاملContact Angle at the Leading Edge Controls Cell Protrusion Rate
Plasma membrane tension and the pressure generated by actin polymerization are two antagonistic forces believed to define the protrusion rate at the leading edge of migrating cells [1-5]. Quantitatively, resistance to actin protrusion is a product of membrane tension and mean local curvature (Laplace's law); thus, it depends on the local geometry of the membrane interface. However, the role of ...
متن کاملCell motility: Complex dynamics at the leading edge
The intracellular pathogen Listeria monocytogenes is a useful model for general actin-based cell motility, because it recruits host actin and associated proteins for movement. Recent data have shown that these associated proteins include the Ena/VASP family of proteins and the actin-related proteins Arp2 and Arp3.
