Method of treating cytomegalovirus with DC-SIGN blockers
First Claim
1. A method of treating a cytomegalovirus (CMV) infection of a human, wherein the infection is mediated at least in part by the binding of a CMV effector molecule on the CMV virus to at least one DC-SIGN receptor selected from DC-Specific ICAM-Grabbing Nonintegrin (DC-SIGN) and DC-Specific ICAM-Grabbing Nonintegrin Related (DC-SIGNR) of the human to be treated, the method comprising:
- administering to the human a mannosylated molecule that specifically binds to the DC-SIGN receptor;
wherein the mannosylated molecule that specifically binds to the DC-SIGN receptor is administered in an amount sufficient to inhibit binding of the CMV virus to the DC-SIGN receptor present on a cell of the human, to thereby treat the CMV virus infection.

Abstract
The present invention relates to methods and compositions for preventing or treating diseases of a mammal, including viral infections, wherein at least one symptom of the disease is mediated at least in part by the binding of an effector molecule to a DC-SIGN receptor present on cells of the mammal to be treated. The invention also provides methods of identifying compositions, wherein the compositions are useful for treating mammalian diseases, including viral infections, for which at least one symptom of the disease is mediated at least in part by the specific binding of an effector molecule to a DC-SIGN receptor present on the cells that express the DC-SIGN receptor, belonging to the mammal to be treated. The invention further relates to compositions and methods for targeting subject molecules to cells that express the DC-SIGN receptor.

1. A method of treating a cytomegalovirus (CMV) infection of a human, wherein the infection is mediated at least in part by the binding of a CMV effector molecule on the CMV virus to at least one DC-SIGN receptor selected from DC-Specific ICAM-Grabbing Nonintegrin (DC-SIGN) and DC-Specific ICAM-Grabbing Nonintegrin Related (DC-SIGNR) of the human to be treated, the method comprising:
-
administering to the human a mannosylated molecule that specifically binds to the DC-SIGN receptor; wherein the mannosylated molecule that specifically binds to the DC-SIGN receptor is administered in an amount sufficient to inhibit binding of the CMV virus to the DC-SIGN receptor present on a cell of the human, to thereby treat the CMV virus infection. - View Dependent Claims (6)

7. A method of inhibiting entry of a CMV virus into a cell of a human that expresses at least one DC-SIGN receptor selected from DC-SIGN and DC-SIGNR of the human to be treated, the method comprising administering to the human a mannosylated molecule that specifically binds to the DC-SIGN receptor;
wherein the mannosylated molecule that specifically binds to the DC-SIGN receptor is administered in an amount sufficient to inhibit the binding of the CMV virus effector molecule to the DC-SIGN receptor, to thereby inhibit entry of the CMV virus into the cell. - View Dependent Claims (12)
