Buildup of a protein called filamentous actin, or F-actin, in the brain inhibits the removal of cellular wastes, including DNA, lipids, proteins and organelles. The resulting accumulation of waste diminishes neuronal functions and contributes to cognitive decline.

Tiny things matter -- for instance, one amino acid can completely alter the architecture of the cell. Researchers have now investigated the structure and mechanics of the main component of the ... Actin filaments are dynamic protein-fibers in the cell built from single actin proteins. Many cellular functions, including cell movement, are regulated by constant filament assembly and disassembly. ...
When an actin filament bends during cell movement, older actin deforms differently than newer actin, allowing regulatory proteins to tell the two states ... Actin filaments are protein fibers that make up the internal skeleton of the cell. As active elements of our cells, actin filaments support the cell's fusion, movement and are involved in many other ...
