Chemokines, including RANTES, play a crucial role in the processes of inflammation during cardiovascular disorders, including myocardial infarction, disease progression and complications. This study aimed to evaluate the role of RANTES -403G/A polymorphism and levels in circulation in processes of development and progression of myocardial infarction and cardiogenic shock. A total of 609 patients with ST-segment elevation myocardial infarction, 43 patients with cardiogenic shock and 130 control subjects were enrolled in the study. RANTES -403G/A promoter polymorphism and baseline serum RANTES levels were analyzed. In the present study, we associated RANTES -403G/A promoter polymorphism with acute heart failure in patients with myocardial infarction (p = 0.006) and ejection fraction 3 months after MI onset (p = 0.02). Further, a difference in circulating RANTES levels among controls and STEMI subjects, and a relation of serum levels with acute heart failure was observed (p = 0.03, p = 0.003, respectively). We found a significant difference when comparing cardiogenic shock patients and controls (p < 0.001), with the most significant difference between cardiogenic shock and AHF subgroup of STEMI patients (p < 0.001). We observed a decreasing tendency of serum RANTES levels with the severity of myocardial infarction and progression, with the lowest levels in patients with cardiogenic shock (cutoff level ≥80.4 ng/ml). Our results suggest the role of RANTES as a potential biomarker of cardiogenic shock and acute heart failure in the hospital phase after myocardial infarction.

Viral CC chemokine inhibitor (vCCI) of the clone P13 vaccinia virus (VACV) strain PRAHA lacks eight amino acids in the signal peptide sequence. To study the influence of vCCI on virus biology, a virus with the vCCI gene coding for a prolonged signal sequence was prepared. We found that secreted vCCI attenuated the virus in vivo, and that it correlated with decreased levels of RANTES, eotaxin, TARC, and MDC in the blood in comparison with the parental virus. We determined the influence of vCCI on the CTL response against VACV E3((140-148)) (VGPSNSPTF) and HPV16 E7((49-57)) (RAHYNIVTF) H-2D(b)-restricted epitopes. The examination of the specific CTL response elicited by immunization with the recombinant VACV-expressing tumor-associated HPV16 E7 antigen by IFN-γ ELISPOT showed that the immunogenicity of the recombinant VACV-producing secretory vCCI was similar to that of the parent virus or deletion mutant in the C23L/B29R locus. Immunization with the secretory vCCI-producing recombinant virus has a lower therapeutic anti-tumor effect against TC-1 tumors. Viral CCI downregulated the E7-specific response induced by gene gun immunization with the DNA vaccines pBSC-SigE7 LAMP and pBSC-vCCI. We also observed that the immune response against vCCI elicited by the DNA vaccine did not affect the multiplication of VACV in vivo.

The MCP-1/CCL2 as well as RANTES/CCL5 chemokines are potent chemoattractants involved in immunoregulatory and inflammatory processes of rheumatoid arthritis. Recent studies demonstrated elevated levels of MCP-1 and RANTES in plasma, synovial fluid, and the synovial tissue of patients with RA. To examine the relationship among MCP-1 and RANTES single nucleotide polymorphisms and circulating levels and rheumatoid arthritis (RA), a total of 156 RA patients and 125 controls were recruited into the study. An association of -855 C/G MCP-1 polymorphism to IgM RF within the RA patients was observed. The lowest circulating levels of RANTES were observed in the AA variant of RANTES -403 G/A polymorphism. Furthermore, an association of -403 AA variant to circulating levels of IL-15 and IL-10 was found. No associations of factors describing rheumatoid arthritis (RFs, ANA, anti-CCP-positive/negative, DAS 28 score and number of swollen joints) with MCP-1 levels, genotype distribution, allelic frequencies and/or frequencies of haplotypes composed of all three studied polymorphisms in promoter region of MCP-1, and RANTES polymorphism were observed. We conclude that the RANTES promoter polymorphism is associated to circulating levels of RANTES, IL15 and IL10. However, our findings suggest that polymorphisms in the MCP-1 and RANTES gene promoters do not contribute significantly to the interindividual RA susceptibility and/or severity in Caucasians.
