Objective: to examine the possible association of CCR2-V64I and MCP-1-2518A/G polymorphisms with generalised aggressive periodontitis (GAgP) in the Chinese population.
Methods: one hundred and twenty-four GAgP patients and 94 healthy subjects were included in the study. A peripheral blood sample was obtained from each subject and genomic DNA was isolated. Gene polymorphisms of CCR2-V64I and MCP-1-2518A/G were analysed by standard polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay.
Results: a possible combined effect of CCR2-V64I and MCP-1-2518A/G was observed in the female GAgP patients, as the odds ratio for VV genotype (CCR2) and G+ genotype ( MCP-1) was 0.2 (P = 0.023). Individuals carrying VV genotype and G+ genotype were at reduced risk for GAgP. A possible combined effect of genotype and smoking was observed in the male GAgP patients, as the odds ratio for VV genotype (CCR2) and smoking, or G+ genotype (MCP-1) and smoking were 7.4 (P = 0.022) and 4.9 (P = 0.030), respectively.
Conclusion: the combined association of CCR2-V64I and MCP-1-2518A/G polymorphisms may play an important role in determining GAgP susceptibility in Chinese females. A possible combined effect of genotype and smoking on GAgP susceptibility was suggested in males.

. Recent studies have revealed that inflammatory processes are involved in the pathogenesis of Parkinson's disease (PD). Multiple lines of evidence have suggested that chemokines and their receptors are involved in several neurodegenerative disorders.

Monocyte chemoattractant protein-1 (MCP-1) and its receptor CC chemokine receptor-2 (CCR2) play important roles in neuroinflammation and they have been shown to be involved in Parkinson's disease (PD) pathogenesis. In addition, several studies have suggested a role for the MCP-1 and CCR2 genotypes in cognitive impairment and depression, which are common non-motor symptoms in PD patients. In this study, a cohort of 521 PD patients and 556 cases of healthy controls were recruited to investigate the association between the MCP-1 2518A/G (rs1064211) and CCR2 V64I (rs1799864) gene polymorphisms and PD risk in the Chinese population.

Studies investigating the impact of polymorphisms on monocyte chemotactic protein-1 (MCP-1) and CC chemokine receptor 2 (CCR2) on the risk of cancer have reported inconsistent results. We performed a meta-analysis of 23 eligible studies to summarize the data describing the association between cancer risk and polymorphisms in MCP-1 A2518G and CCR2 V64I. Q-statistics and I(2) statistics were calculated to examine heterogeneity and summary odds ratios (ORs) and 95% confidence intervals (95% CI) were calculated using a random effects model.

Purpose: Chemokines are important inflammatory mediators that play a crucial role in uveitis. Polymorphisms in chemokine genes can alter the expression of these genes in the inflammatory cells, which, in turn, can affect the clinical phenotype of the disease. The purpose of this study was to identify polymorphisms in chemokine genes that can predict visual outcome in patients with immune-mediated posterior segment uveitis.
