Description
  • Práce popisuje, že aktivace tool-like receptoru-9 indukuje progresi renálního onemocnení u MRL-Fas(lpr) myší (cs)
  • How bacterial or viral infections trigger flares of autoimmunity is poorly understood. As toll-like receptor (TLR)-9 activation by exogenous or endogenous CpG-DNA may contribute to disease activity of systemic lupus erythematosus, we examined the effects of CpG-oligodeoxynucleotides (ODN) or DNA derived from Escherichia coli (E. coli) on the course of nephritis in MRL1pr/1pr mice. In kidneys of these mice, TLR9 localized to glomerular, tubulointerstitial, and perivascular infiltrates. After intraperitoneal injection labeled CpG-ODN localized to glomerular and interstitial macrophages and dendritic cells in nephritic kidneys of MRL1pr/1pr mice but not in healthy MRL controls. Furthermore, murine J774 macrophages and splenocytes from MRL1pr/1pr mice, but not tubular epithelial cells, renal fibroblasts, or mesangial cells, expressed TLR9 and up-regulated CCL5/RANTES mRNA upon stimulation with CpG-ODN in vitro. In vivo both E. coli DNA and CpG-ODN increased serum DNA autoantibodies of the IgG(2a) isotype
