Moreover, in 35 patients with drug-naïve SLE (n = 35), we investigated correlation between NETs-associated markers [DNase I concentration, myeloperoxidase (MPO) activity, anti-MPO antibodies, cell-free DNA (cfDNA), NETolytic activity] with serological parameters [anti-dsDNA antibodies, C3, C4 and B-cell activating factor (BAFF) levels] and disease activity measured by modified SLE Disease Activity Index (M-SLEDAI-2K).
Most Dnase1 and Dnase2 family members are poorly characterized, yet their elimination can lead to a wide range of diseases, including lethal anemia, parakeratosis, cataracts and systemic lupus erythematosus.
Identification of the functional alleles of the nonsynonymous single-nucleotide polymorphisms potentially implicated in systemic lupus erythematosus in the human deoxyribonuclease I gene.
The aim of our work was to evaluate the DNASE1 contribution in the genetic susceptibility of rheumatoid arthritis (RA, n = 151), Sjögren syndrome (SS, n = 55) and SLE (n = 34) in Tunisia.
DNase I does not correlate with sFas or sFasL, whereas it correlates with T cell surface Fas expression that is higher in patients with active SLE than in healthy controls.
Its relationship with SLE susceptibility, serum DNase I activity, anti-ribonucleoprotein (RNP), anti-double-stranded DNA (dsDNA), anti-nucleosome and anti-single-stranded DNA (ssDNA) antibodies was determined.
Genetic associations of polymorphisms in DNase I with the risk of SLE and the production of common autoantibodies were examined in a Korean population (350 SLE patients and 330 controls).
The purpose of this study was to genotype the single nucleotide polymorphisms (SNPs) of DNase1 and characterize its gene expression and alternatively spliced transcripts in Chinese patients with SLE in order to understand the pathogenic role of DNase1 in human SLE.
Thus, here we review current findings about the association of the defective clearance of autoantigens and SLE, focusing on mutations in the DNase I locus and their relationship to SLE.
