Abstract
Aim
It has been reported that tumor necrosis factor (TNF)-α plays dual controversial roles, beneficial or detrimental, in the pathogenesis of murine lupus nephritis (LN). However, its precise role in the development of human LN remains to be determined.
Methods
We examine the effect of pretreatment with TNF-α on the toll-like receptor 3 (TLR3) signaling induced by polyinosinic-polycytidylic acid (poly IC), a synthetic analog of viral dsRNA that makes “pseudoviral” infection in cultured normal human mesangial cells, and analyzed the expression of CC chemokine ligand 5 (CCL5) via TLR3/interferon (IFN)-β/retinoic acid-inducible gene-I (RIG-I) pathway by reverse transcriptase-polymerase chain reaction, Western blotting and enzyme-linked immunosorbent assay.
Results
We found synergistic effect of TNF-α, even at low level, on the expression of CCL5 induced by poly IC in a concentration-dependent manner, in comparison with that by poly IC alone. Knockdown of either IFN-β or RIG-I decreased CCL5 expression induced by TNF-α followed by poly IC.
Conclusion
Pretreatment with TNF-α leads marked activation of the TLR3/IFN-β/RIG-I/CCL5 axis induced by “pseudoviral” infection. Since chronic local activation of proinflammatory cytokines including TNF-α in resident renal cells may exist in patients with active lupus, synergistic effect of TNF-α and “pseudoviral” infection is possibly involved in the development of LN.
