Treatment with DNAse I fosters binding to nec PBMC of CRP

Abstract

CRP is an important inflammatory marker, however, CRP levels are relatively low in patients with SLE. In addition patients with SLE often display low activities and serum levels for DNase I and complement, respectively. Here we show that DNase I treatment of nec PBMC increased their binding of CRP. Consequently, reduced DNase I activity in patients with SLE may contribute to the impaired opsonisation by CRP of dead cells, exacerbating the clearance defect in SLE of apo and nec cells.
