Study on plasma CC chemokine ligand 2 level and its promoter region 2518A/G polymorphism in MS patients

The increase of CC chemokine ligand 2 (CCL2) is associated with multiple sclerosis (MS), but the relationship between gene promoter region 2518A/G and the pathogenesis of MS is still not obvious. Collected 54 cases of relapsing-remitting MS patients and 54 healthy controls. By detecting the CCL2-2518A/G polymorphism of MS patients and analyzing the plasma CCL2 level. High levels of A/A genotype and A allele frequency in serum CCL2 and PBMC were found in MS patients. The serum CCL2 of MS patients with A/A genotype is higher than other genotypes. Lipopolysaccharide stimulated PBMC, CCL2 levels in the supernatant of all genotypes were higher, and the A/A genotype levels of MS patients were the highest. Finally, CCL2-2518A/G polymorphism is related to the pathogenesis of MS.
