Disease relevance of CCL8

 

High impact information on CCL8

  • Dendritic cells in the lymph nodes of macaques infected with simian immunodeficiency virus (SIV) have elevated levels of monocyte chemoattractant protein 2 (MCP-2), demonstrating that chemokine induction also occurs during retroviral infection in vivo [6].
  • These results demonstrate that MCP-1, MCP-2, and MCP-3 are inflammatory mediators that specifically stimulate the directional migration of T cells as well as monocytes and may play an important role in immune cell recruitment into sites of antigenic challenge [7].
  • Of note, the addition of optimal concentrations of recombinant CCL8 plus CXCL10 to endothelial cultures completely restored the proadhesive activity of TNF-alpha [8].
  • TRAIL counteracts the proadhesive activity of inflammatory cytokines in endothelial cells by down-modulating CCL8 and CXCL10 chemokine expression and release [8].
  • A29S displayed an unusual pharmacological profile, binding and responding to MCP-2 similarly to wtCCR5, but exhibiting severely impaired binding and functional responses to MIP-1alpha, MIP-1beta, and RANTES [9].

Associations of CCL8 with chemical compounds

 

Physical interactions of CCL8

  • Desensitization studies indicate that MCP-2 interacts with receptors recognizing MCP-1 as well as RANTES [15].
  • MCP-2 is a potent inhibitor of HIV-1 by virtue of its high-affinity binding to the receptor CCR5, one of the major coreceptors for HIV-1 [20].
 

Regulatory relationships of CCL8

  • At 4 nM, MCP-2 induced a Ca2+ influx which was as potent as that with MCP-1 at 4 nM, although the increase by MCP-2 became saturated at higher concentrations [21].
  • Monocyte chemotactic protein-2 activates CCR5 and blocks CD4/CCR5-mediated HIV-1 entry/replication [2].
  • We demonstrate that MCP-2 specifically inhibits replication of R5 HIV-1 and that this activity is additive to that of RANTES [5].
 

Other interactions of CCL8

  • We conclude that MCP-3, but not MCP-2, is a functional ligand for the MCP-1 receptor [13].
  • In this study, we have examined potential interactions of MCP-2 and MCP-3 with the recently cloned MCP-1 receptor [13].
  • Both CCR1- and CCR2B-transfected 293 cells showed significant migration in response to MCP-2, in addition to responding to other specific chemokines [11].
  • In conclusion, our study suggests a possible role of the polymorphisms CCR5-delta32, RANTES -403, and MCP-2 Q46K in the outcome of HCV infection [1].
  • Monocyte chemoattractant protein-2 is a potent agonist of CCR2B [22].
