Summary
Immune cell migration relies on energy and is influenced by metabolism. This review explores how cytoskeletal dynamics, chemokine receptors, and environmental factors interact with cellular energy production during immune responses.
Area of Science:
- Immunology
- Cell Biology
- Metabolic Research
Background:
- Cell migration is crucial for immunity, requiring significant energy.
- Immune cell navigation is guided by chemokines and mediators, especially during inflammation.
- Factors like cytoskeletal remodeling, receptor expression, and environment impact cell migration.
Purpose of the Study:
- To review recent advances linking immune cell migration to cellular metabolism.
- To focus on the interplay between glycolysis, mitochondria, chemokine receptors, and environmental factors.
- To provide insights into the metabolic demands of immune cell movement.
Main Methods:
- Literature review of recent research on cell migration and metabolism.
- Analysis of the spatial organization of glycolysis and mitochondria in migrating cells.
- Examination of the reciprocal regulation of chemokine receptors and environmental influences.
Main Results:
- Cellular metabolism, particularly glycolysis and mitochondrial function, is spatially organized to support migration.
- Chemokine receptor expression and function are reciprocally regulated by metabolic states.
- Environmental conditions significantly modulate immune cell migration through metabolic adaptations.
Conclusions:
- Understanding the metabolic underpinnings of cell migration is key to modulating immune responses.
- Targeting metabolic pathways could offer new strategies for immune-related diseases.
- The spatial and temporal coordination of metabolism is critical for effective immune cell trafficking.

01:19Cell Migration
6.1K
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, 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.

01:21Chemotaxis and Direction of Cell Migration
4.2K
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...

01:32Cytoskeletal Coordination in Cell Migration
5.3K
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...

01:18Role of Myosin in Cell Migration
2.9K
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....
