The role of rabbit Ia molecules in immune functions as determined with the use of an anti-Ia monoclonal antibody.

abstract：:Hepatitis C virus (HCV) infection is a global health problem characterized by a high rate of chronic infection, which may in part be due to a defect in myeloid dendritic cells (mDCs). This defect appears to be remedied by treatment with interferon-α (IFN-α) -based antiviral therapies; however, the molecular mechanisms...
