Methods for inhibiting HIV or HCV infection by administering TIM-3 binding inhibitors
The application relates to methods of treating chronic viral infection by modulating Tim-3 activity. In addition, the present application relates to methods of diagnosing or monitoring immune system activity or function, chronic viral infection and inflammatory disease using Tim-3 expression.
1. A method for inhibiting a viral infection in a subject in need thereof comprising administering an effective amount of an inhibitor of T-cell immunoglobulin and mucin domain-containing molecule 3 (Tim-3), wherein the inhibitor is a means for binding Tim-3, and wherein the viral infection is a human immunodeficiency virus (HIV) infection or a hepatitis C virus (HCV) infection, and wherein the Tim-3 to which the inhibitor binds has at least 90% sequence identity to SEQ ID NO: 2 or 6.
2. The method of claim 1 , wherein the viral infection is a chronic viral infection.
3. The method of claim 1 , further comprising administering an effective amount of an antigen expressed by a virus that causes a chronic infection.
4. The method of claim 3 , wherein the chronic virus is human immunodeficiency virus type 1 (HIV-1) or hepatitis C virus (HCV).
5. The method of claim 1 wherein the viral infection is a human immunodeficiency virus (HIV) infection.
6. The method of claim 1 wherein the viral infection is a hepatitis C virus (HCV) infection.
7. The method of claim 1 wherein the means for binding Tim-3 comprises an anti-Tim-3 antibody that specifically binds to an amino acid sequence according to SEQ ID NO: 2 or 6.
