Disease relevance of CX3CL1

 

High impact information on CX3CL1

 

Chemical compound and disease context of CX3CL1

  • The effects of AS-6 on TNF-alpha-stimulated VCAM-1 and CX3CL1 expression were abolished in cells transfected with an adenovirus expressing dominant-negative PPARgamma and in cells treated with a PPARgamma specific inhibitor, GW9662, confirming again that the anti-inflammatory effect of AS-6 was PPARgamma-dependent [8].
  • Alterations in the expression of the chemokine, fractalkine (CX3CL1), were examined in the urinary bladder after cyclophosphamide (CYP)-induced cystitis of varying duration: acute (4 h or 48 h), or chronic (10 day) [9].
  • Alpha-lipoic acid inhibits fractalkine expression and prevents neointimal hyperplasia after balloon injury in rat carotid artery [10].
  • Moreover, FKN significantly reduced neuronal NMDA-induced apoptosis, which was pertussis toxin insensitive and abolished in presence of PD98059 and LY294002 [11].
  • Application of FKN triggered a 53% reduction of the NMDA-induced neuronal calcium influx, which was insensitive to pertussis toxin and LY294002 an inhibitor of Akt pathway, but abolished by PD98059, an ERK1/2 pathway inhibitor [11].
 

Biological context of CX3CL1

 

Anatomical context of CX3CL1

  • Using human pancreatic islets as an in vitro model of peripheral tissue, we showed that islet supernatants released factors able to attract BM-MSCs in vitro, and this attraction was principally mediated by CX3CL1 and CXCL12 [17].
  • The membrane-anchored form of CX3CL1 has been proposed as a novel adhesion protein for leukocytes [13].
  • Compatible with this hypothesis, stimulation of monocytes with MCP-1 significantly increased their adhesion to immobilized CX3CL1, under both static and physiological flow conditions [13].
  • METHODS: Using flow cytometry, immunohistochemistry, and reverse transcription-polymerase chain reaction, we analyzed CX3CR1 expression by peripheral blood and synovial T cells, and CX3CL1 expression in synovium from patients with RA [18].
  • Endometrial cell-conditioned media also stimulated trophoblast migration; this was attenuated by neutralizing antibodies to CX3CL1 and CCL4 [19].
 

Associations of CX3CL1 with chemical compounds

 

Physical interactions of CX3CL1

  • In steady state experiments, all three CX3CR1 isoforms bound CX3CL1 with similar affinity [25].
  • Fractalkine (CX3CL1) is a transmembrane molecule with a CX3C chemokine domain attached to an extracellular mucin stalk which can induce both adhesion and migration of leucocytes [26].
 

Co-localisations of CX3CL1

 

Regulatory relationships of CX3CL1

  • Combined stimulation with IFN-gamma and TNF-alpha induced FKN mRNA and protein expression in a time- and concentration-dependent manner [23].
  • RESULTS: Flow cytometric analysis of fractalkine-expressing T cell subsets revealed a low proportion of fractalkine-expressing CD4+ and CD8+ T cells in both RA patients and controls [28].
  • There is a positive correlation between the number of fractalkine-expressing cells and the number of CX3CR1-positive cells in human atherosclerotic plaques (r=0.70, n=15 plaques) [29].
  • Moreover, the membrane form of fractalkine expressed on ECV304 cells reduced MCP-1 mediated chemotaxis of THP-1 cells [30].
  • Furthermore, we observed that s-FKN also inhibits the activity of a major matrix metalloproteinase (MMP), namely MMP-2 [15].
 

Other interactions of CX3CL1

  • These results demonstrate that FKN preferentially mediates arrest and migration of CD16+ monocytes and suggest that recruitment of this proinflammatory monocyte subset to vessel walls via the CX3CR1-FKN pathway may contribute to vascular and tissue injury during pathological conditions [31].
  • Inhibition of ADAM10-mediated CX3CL1 shedding not only increased adhesive properties of CX3CL1-ECV-304 cells but also prevented de-adhesion of bound THP-1 cells [12].
  • High levels of MDC, TARC, and fractalkine mRNA expression are seen in some, but not all, human arteries with advanced atherosclerotic lesions [32].
  • Unlike other human chemokines, the chemokine domain of fractalkine has three amino acids between two conserved cysteines, referred to as the CX3C motif [33].
  • In this study, we address the question of the cross-talk between two chemokines that are cosecreted during inflammation, namely monocyte chemoattractant protein-1 (MCP-1) and soluble fractalkine (s-FKN), toward monocyte migration [15].
