Abrogating ClC-3 Inhibits LPS-induced Inflammation via Blocking the TLR4/NF-κB Pathway
This study investigated the function of a chloride channel blocker, DIDS. Both in vitro and in vivo studies found that DIDS significantly inhibits lipopolysaccharide (LPS)-induced release of proin flammatory cytokines. Here, we show that DIDS inhibits LPS-induced inflammation, as shown by downregula...

Sumario: | This study investigated the function of a chloride channel blocker, DIDS. Both in vitro and in vivo studies found that DIDS significantly inhibits lipopolysaccharide (LPS)-induced release of proin flammatory cytokines. Here, we show that DIDS inhibits LPS-induced inflammation, as shown by downregulation of inflammatory cytokines via inhibition of the TLR4/NF-κB pathway. Furthermore, we show that ClC-3siRNA transfection reduces LPS-induced pro-inflammation in Raw264.7 cells, indicating that ClC-3 is involved in the inhibitory effect of DIDS during LPS-induced cytokines release. In vivo, DIDS reduced LPS-induced mortality, decreased LPS-induced organic damage, and down-regulated LPS-induced expression of inflammatory cytokines. In sum, we demonstrate that ClC-3 is a pro-inflammatory factor and that inhibition of ClC-3 inhibits inflammatory induction both in vitro and in vivo, suggesting that ClC-3 is a potential anti-inflammatory target. |
