Summary Systemic lupus erythematosus ( SLE ) is a prototypical autoimmune disease with strong genetic and environmental components. Previous studies have shown increased levels of several chemokines in active SLE . C‐C chemokine receptor type 5 ( CCR 5) is involved in the recruitment of inflammatory cells into tissues, and mechanisms modulating CCR 5 expression and function may interfere in SLE development, influencing the clinical course of the disease. The aim of this study was to evaluate the possible association between the CCR 5∆32 base‐pair deletion polymorphism and SLE disease in a group of Portuguese patients. A total of 219 patients with SLE and 205 healthy individuals were studied. The frequency of CCR 5/∆32 heterozygotes was lower in patients with SLE than in controls (8% vs. 15% OR = 0.5162; P = 0.0319), suggesting a protective association between CCR 5∆32 allele and SLE . These results highlight the protective role of Th1 cells that express CCR 5 in SLE pathogenesis.
