This invention provides a method of inhibiting HCV infection of a cell susceptible to HCV infection which comprises contacting the cell with an amount of a compound effective to inhibit binding of an HCV envelope glycoprotein to a DC-SIGN protein present on the surface of the cell, so as to thereby inhibit HCV infection of the cell susceptible to HCV infection. This invention provides a method of inhibiting HCV infection of a cell susceptible to HCV infection which comprises contacting the cell with an amount of a compound effective to inhibit binding of an HCV envelope glycoprotein to a DC-SIGNR protein present on the surface of the cell, so as to thereby inhibit HCV infection of the cell susceptible to HCV infection. Compounds of the present invention inhibit HCV infection of cells susceptible to HCV infection. The compounds of the present invention preferably have specificity for preventing or inhibiting infection by HCV and do not inhibit infection by other viruses, such as HIV, that may utilize DC-SIGN or DC-SIGNR for infection. Moreover the compounds of the present invention preferably do not interfere or inhibit members of the immunoglobulin superfamily, in particular, the compounds do not interfere with ICAM-2 or ICAM-3 or with ICAM-2-ilke, or ICAM-3-like molecules.
A method of inhibiting in vivo Hepatitis C Virus (HCV) infection of a liver hepatocyte cell susceptible to HCV infection which comprises contacting a liver sinusoidal cell with an amount of an antibody or a portion thereof effective to inhibit binding of an HCV envelope glycoprotein to a DC-SIGNR protein present on the surface of the liver sinusoidal cell, so as to thereby inhibit HCV infection of the liver hepatocyte cell susceptible to HCV infection, wherein the antibody or portion thereof binds to the DC-SIGNR protein.
