| Research Abstract |
Kawasaki disease (KD) is an acute febrile vasculitic syndrome of unknown etiology preferentially affecting Japanese children. In this project, we reported an enhanced expression of MCP-1 in the coronary vessels infiltrated by macrophages in fatal KD, suggesting a role of MCP-1 in the pathogenesis of KD.
Recently, the polymorphism at position -2518 (G or A), relative to the major transcriptional start site of the MCP-1 gene, was shown to influence the level of MCP-1 production in response to interleukin 1β in vitro (Rovin et al). We reproduced this in vitro effect of MCP-1 production using 18 Japanese healthy volunteers. PBMC from Japanese individuals who carry the -2518 G allele(high production of MCP-1) produced more MCP-1 than hoinozygotes for the A allele (low production of MCP-1) (p<0.01 by unpaired Welch's t test), consistent with an earlier study.
The A allele was found to be predominant among Caucasian and African American populations, suggesting a possible ethnic variation. The G/A polymorphism in Japanese population has not been investigated. Informed consent for this study was obtained from all subjects before the study. The observed genotype and allele frequencies showed that G allele (high production of MC-1 was largely predominant among the Japanese population. The frequency of the A allele was 35 % and that of the G allele was 65 %. In addition, the serum levels of MCP-1 in KD patients with G allele were higher than those in homozygotes for the A allele, although the statistical significance was not obtained when tested by Mann-Whitney U test (p = 0.24). In conclusion, the high prevalence of G allele in the distal regulatory region of the MCP-1 gene in Japanese may suggest a potentially important ethnic variation in the regulation of MCP-1 production, which may contribute to the pathogenesis of KD.
