The gram-positive bacterium Listeria monocytogenes is the causative agent of listeriosis, a
highly fatal opportunistic foodborne infection. Pregnant women, neonates, the elderly, and …

To migrate, a cell first extends protrusions such as lamellipodia and filopodia, forms
adhesions, and finally retracts its tail. The actin cytoskeleton plays a major role in this …

The leading edge (∼ 1 μm) of lamellipodia in Xenopus laevis keratocytes and fibroblasts
was shown to have an extensively branched organization of actin filaments, which we term …

Spermatogenesis is the process by which a single spermatogonium develops into 256
spermatozoa, one of which will fertilize the ovum. Since the 1950s when the stages of the …

We have found that epithelial cells engage in a process of cadherin-mediated intercellular
adhesion that utilizes calcium and actin polymerization in unexpected ways. Calcium …

Completely revised, this third edition of a bestseller incorporates findings to present readers
with a complete overview of foodborne listeriosis, including information on listeriosis in …

▪ Abstract Ena/VASP proteins are a conserved family of actin regulatory proteins made up of
EVH1, EVH2 domains, and a proline-rich central region. They have been implicated in actin …

Actin polymerization is essential for cell locomotion and is thought to generate the force
responsible for cellular protrusions. The Arp2/3 complex is required to stimulate actin …

3-3σ is a member of a family of proteins that regulate cellular activity by binding and
sequestering phosphorylated proteins. It has been suggested that 14-3-3σ promotes pre …

▪ Abstract Eukaryotic cells use actin polymerization to change shape, move, and internalize
extracellular materials by phagocytosis and endocytosis, and to form contractile structures …
