Abstract

Background: Current evidence shows that the CD40-CD40 ligand (CD40-CD40L) system plays a crucial role in the development, progression and outcome of systemic lupus erythematosus (SLE). The aim of this study was to investigate whether a CD40 gene single nucleotide polymorphism (SNP) is associated with SLE and CD40 expression in the Chinese population. We included controls (n = 220) and patients with either SLE (n =205) in the study.

Methods: The gene polymorphism was measured using Snapshot SNP genotyping assays and confirmed by sequencing. We analyzed three single nucleotide polymorphisms of CD40 gene rs1883832C/T, rs1569723A/C and rs4810485G/T in 205 patients with SLE and 220 age-and sex-matched controls. Soluble CD40 (sCD40) levels were measured by ELISA.

Results: There were significant differences in the genotype and allele frequencies of CD40 gene rs1883832C/T polymorphism between the group of patients with SLE and the control group (P < 0.05). sCD40 levels were increased in patients with SLE compared with controls (P < 0.01). Moreover, genotypes carrying the CD40 rs1883832 C/T variant allele were associated with increased CD40 levels compared to the homozygous wild-type genotype in patients with SLE. The rs1883832C/T polymorphism of CD40 and its sCD40 levels were associated with SLE in the Chinese population.

Conclusions: Our results suggest that CD40 gene may play a role in the development of SLE in the Chinese population.

The levels of CD40 in patients with SLE and normal control subjects. The expression of CD40 was significantly increased in patients with SLE compared to that in control subjects [(mean +/− SD 41.7+/− 13.2 pg/ml, n = 205) vs (mean +/− SD 58.5+/− 22.8 pg/ml, n = 220); P <0.001]

Association between the levels of CD40 and the rs1883832 C/T polymorphism of CD40 gene was observed in patients with SLE. Plasma CD40 levels with CC homozygous were significantly lower than that of the TT homozygous or CT heterozygotes, respectively. However, there were no significant differences in the plasma CD40 levels between CT and TT genotypes
