Protein lifetime and the stability of cell structures

(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...

Watch immune cells dig tunnels in tissues

White blood cells called cytotoxic T lymphocytes (CTLs) dig tunnels in tissues, potentially allowing other CTLs to quickly reach infected cells and tumor cells, researchers report December 1st in Biophysical Journal. The ...

Making progress toward the prevention of collagen-related diseases

A collaboration between groups from France and the UK, led by researchers from the Institut de Biologie et Chimie des Protéines, have just determined the three-dimensional structure of a key region of the procollagen molecule, ...

Citrate key in bone's nanostructure

Bone is one of nature's surprising "building materials." Pound-for-pound it's stronger than steel, tough yet resilient. Scientists at the U.S. Department of Energy's Ames Laboratory have identified the composition that ...
