... bind each other’s metals, they are inactive when the wrong metal is incorporated at the active site [3]. However, several SODs are active in the presence of either Fe or Mn. These types of SODs ... ligands in the Mn-reconstituted enzyme and an additional water oxy- gen, which, together with the OD2 of Asp165, the NE2 of His79 and the NE2 of His169, formed an eq...

... that the activation of IRF-3 by M-pIC treatment is mediated by the TLR3 ⁄ TRIF signaling pathway. We obtained further evidence by examining the status of the phos- phorylation and dimerization of ... PH5CH8 cells. First, we confirmed the effect of NS3-4A on the activation of the IFN-b gene promoter by the Cardif exogenously expressed in PH5CH8 cells. The results...
