Cytoskeletal Coordination in Cell Migration

Cytoskeletal Coordination in Cell Migration

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 proteins that...

Cell Migration

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Chemotaxis and Direction of Cell Migration

Chemotaxis and Direction of Cell Migration

Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...

Role of Myosin in Cell Migration

Role of Myosin in Cell Migration

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. It is...

Cancer Cell Migration through Invadopodia

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...

Summary

This study models cell migration in 3D matrices, revealing that matrix metalloproteinases (MMPs) and ligand levels impact cell motility. Peak cell speed occurs at intermediate or low ligand/high MMP levels, depending on MMP-integrin feedback.

Background:

Cell migration is vital for physiological processes.
Three-dimensional (3D) matrices present unique challenges compared to 2D systems.
Cell-matrix interactions, particularly involving matrix metalloproteinases (MMPs), are critical for 3D cell motility.

Purpose of the Study:

To computationally model 3D cell migration incorporating MMP-mediated proteolysis.
To investigate the impact of different matrix ligand-MMP relationships (linear and log-linear) on cell motility.
To explore the effects of MMP-integrin feedback on cell migration dynamics.

Main Methods:

Developed a force-based computational model for 3D cell migration.
Simulated cell migration under varying matrix ligand and MMP concentrations.
Integrated recent findings on MMP influence on integrin expression into the model.

Main Results:

Predicted maximal cell motility at intermediate ligand and MMP levels for both linear and log-linear relationships.
The linear relationship yielded more physiologically relevant outcomes.
Incorporating MMP-integrin feedback shifted peak cell speed to a low ligand, high MMP scenario.

Conclusions:

Cell-matrix interactions significantly influence cell migration in 3D environments.
MMP activity and integrin feedback play crucial roles in regulating cell speed.
The model provides insights with implications for cancer research and understanding cell motility.
