Summary
Vinculin, a key protein in cell adhesion, regulates cell migration speed and coordination. Its load-bearing function and a specific residue control adhesion strengthening, impacting collective cell migration.
Area of Science:
- Cell Biology
- Biophysics
- Mechanobiology
Background:
- Collective cell migration (CCM) is crucial for development and disease.
- Dynamic mechanical coupling between cells is essential for CCM.
- Understanding how proteins mediate cell adhesion forces is unclear.
Conclusions:
- Vinculin's load-bearing capacity and conformational changes are critical for regulating CCM.
- Adhesion-based friction, modulated by vinculin, is a key factor in CCM dynamics.
- This study provides a molecular basis for how linker proteins tune cell mechanical coupling during CCM.

01:32Cytoskeletal Coordination in Cell Migration
4.8K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

01:13Cell-matrix's Response to Mechanical Forces
2.7K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:26Tension Response at Adherens Junctions
2.7K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.

01:18Role of Myosin in Cell Migration
2.4K
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....

01:16Cell Motility through Blebbing
2.0K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

01:13Actin Polymerization and Cell Motility
5.3K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
