Adiponectin inhibits chemokine-induced cell migration, particularly PF4-driven monocyte movement. This interaction suggests adiponectin

Area Of Science

  • Cardiovascular Biology
  • Immunology
  • Molecular Interactions

Background

  • Adiponectin possesses anti-inflammatory properties, but its role in cardiovascular homeostasis is not fully understood.
  • Mechanisms underlying adiponectin's cardiovascular effects require further elucidation.

Purpose Of The Study

  • To investigate adiponectin's effect on chemokine-induced cell migration.
  • To explore potential intermolecular interactions between adiponectin and chemokines.

Main Methods

  • HL-60 cells were treated with adiponectin and then exposed to recombinant PF4, MCP-1, or RANTES.
  • Cell migration was assessed.
  • Surface plasmon resonance and molecular docking were used to analyze binding interactions.

Main Results

  • Adiponectin significantly inhibited cell migration induced by PF4, MCP-1, and RANTES.
  • Surface plasmon resonance and molecular docking confirmed a high-affinity binding interaction exclusively between adiponectin and PF4.
  • Adiponectin demonstrated a higher affinity for the PF4 binding site.

Conclusions

  • Adiponectin reduces PF4-induced monocyte migration.
  • Direct interaction between adiponectin and PF4 mediates this effect.
  • Adiponectin's atheroprotective functions may involve inhibiting PF4-driven monocyte migration.

Intracellular Signaling Affects Focal Adhesions 01:17

3.5K

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Cancer Cell Migration through Invadopodia 01:35

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,...

Chemotaxis and Direction of Cell Migration 01:21

4.4K

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...

Activation of Integrins 01:15

4.9K

Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Regulation of Angiogenesis and Blood Supply 01:24

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Immunoglobulin-like Cell Adhesion Molecules 01:31

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
