Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease, and IL-1β, IL-10, and TNF-α genes are important in the pathogenesis of this disease. We studied the impact of IL-1β-511, IL-1β +3953, IL-10 -592, IL-10 -1082, TNF-α -308, TNF-α -238, and TNF-α +489 polymorphisms on SLE risk and phenotype in SLE patients and healthy controls.We genotyped SLE patients and healthy controls by real-time PCR on QuantStudio 5 (Applied Biosystems) and measured levels of cytokines by enzyme-linked immunosorbent assay (ELISA).We indicated that TNF-α -308, IL-10 -592, IL-10 -1082, IL-1β-511 and IL-1β +3953 polymorphisms affect SLE risk. Furthermore, we exposed that some of the TNF-α +489, TNF-α -238, IL-10 -1082 and IL-1β +3953 genotypes are connected with the SLE phenotype. Moreover, we discovered the linking between specific genotypes and the serum concentrations of TNF-α, IL-1β, and IL-10.In conclusion, our study revealed that IL-1β-511, IL-1β +3953, IL-10 -592, IL-10 -1082, and TNF-α -308 polymorphisms may affect SLE risk and phenotype.
