摘要:
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 infection 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.

摘要:
This method provides a method for reducing HIV-I viral load in an HIV-1-infected human subject which comprises administering to the subject at a predefined interval effective HIV-I viral load- reducing doses of (a) a humanized antibody designated PRO 140, or of (b) an anti-CCR5 receptor monoclonal antibody. This invention also provides a method for inhibiting in a human subject the onset or progression of an HIV-I -associated disorder, the inhibition of which is effected by inhibiting fusion of HIV-I to CCR5+CD4+ target cells in the subject. This invention also provides a method for treating a subject infected with HIV-I comprising administering to the subject (a) a monoclonal antibody which (i) binds to a CCR5 receptor on the surface of the subject's CD4+ cells and (ii) inhibits fusion of HIV-I to the subject's CCR5+CD4+ cells, and (b) a non-antibody CCR5 receptor antagonist, in amounts effective to treat the subject.
摘要:
This invention provides a composition which comprises an admixture of three compounds, wherein: a) one compound is an antibody which binds to a CCR5 receptor; b) one compound retards attachment of HIV-1 to a CD4+ cell by retarding binding of HIV-1 gp120 envelope glycoprotein to CD4 on the surface of the CD4+ cell; and c) one compound retards gp41 from adopting a conformation capable of mediating fusion of HIV-1 to a CD4+ cell by binding noncovalently to an epitope on a gp41 fusion intermediate; wherein the relative mass ratio of any two of the compounds in the admixture ranges form about 100:1 to about 1:100, the composition being effective to inhibit HIV-1 infection of the CD4+ CELL. This invention also provides a method of inhibiting HIV-1 infection of a CD4+ cell which comprises contacting the CD4+ cell with an amount of the composition of the subject invention effective to inhibit HIV-1 infection of the CD4+ cell so as to thereby inhibit HIV-1 infection of the CD4+ cell.
