Actin polymerization is induced by Arp2/3 protein complex at the surface of Listeria monocytogenes

Article Abstract:

Listeria monocytogenes can execute directed movement within the cytoplasm of infected host cells through actin polymerization at the bacterial cell surface. To understand how actin polymerization is controlled in the cell, the mechanism by which L. monocytogenes polymerizes actin must be understood. Such an actin assembly necessitates the bacterial surface protein ActA and protein components that exist in the host cell cytoplasm. Two subunits of this protein complex are actin-related proteins (ARPs) that belong to the Arp2 and Arp3 subfamilies.

Charge- and size-based separation of macromolecules using ultrathin silicon membranes

Article Abstract:

An ultrathin porous nanocrystalline silicon (pnc-Si) membrane is developed by using straightforward silicon fabrication methods that provide control over average pore sizes. An efficient, low-loss macromolecule separation is provided for pnc-Si membranes in order to enable a variety of new devices like membrane-based chromatography systems and both analytical and preparative microfluidic system requiring highly efficient separations.
