    ..We speculate that the protective effects of HO-1 in injured tissue may involve, at least in part, the capacity of HO-1 to restrain up-regulation of MCP-1. ..

    ..In contrast, adjunctive CoPP treatment decreased IP-10 levels in mouse livers infused with rIFN-beta. Thus, CoPP-induced HO-1 upregulation suppresses type-1 IFN pathway downstream of TLR4 system in hepatic warm I/R injury model. ..

    ..Our data demonstrate that the absence of HO-1 renders animals more susceptible to myocardial ischemia/reperfusion damage and diabetes worsens the injury. ..
