1. A method, comprising:
- detecting an expression profile of at least one gene in a biological sample of a subject; and
comparing said expression profile to a reference expression profile of said at least one gene to detect or monitor an autoimmune disease in said subject, wherein said at least one gene is differentially expressed in pre-symptomatic lupus-affected or -predisposed tissues as compared to disease-free tissues.

Abstract
Compositions and methods for diagnosing, preventing, or treating lupus nephritis (LN), systemic lupus erythematosus (SLE), or other autoimmune diseases. Lupus-related genes (LRGs) are identified in the present invention. These genes are differentially expressed in lupus-affected or lupus-predisposed tissues as compared to disease-free tissues. The genes and their expression products can be used as markers for diagnosing or monitoring SLE or LN. Modulators of the expression or protein activities of these genes can be used for the prevention or treatment of SLE/LN or other autoimmune diseases.

10. A pharmaceutical composition comprising a pharmaceutically-acceptable carrier and at least one active component selected from the group consisting of:
-
a polypeptide encoded by a gene which is differentially expressed in pre-symptomatic lupus-affected or -predisposed tissues as compared to disease-free tissues;

13. A pharmaceutical composition comprising a pharmaceutically-acceptable carrier and at least one active component selected from the group consisting of:
-
an agent capable of modulating the expression of a gene which is differentially expressed in pre-symptomatic lupus-affected or -predisposed tissues relative to disease-free tissues;
an agent capable of binding to, or modulating a biological activity of, a polypeptide encoded by said gene; and
a T cell activated by said polypeptide. - View Dependent Claims (14, 15, 16, 17)

19. A method comprising:
-
contacting an agent with lupus-affected or lupus-predisposed cells;
comparing expression profiles or protein activities of at least one gene in said cells before and after said contacting to determine if said agent modulates expression or protein activity of said at least one gene, wherein said at least one gene is differentially expressed in lupus-affected or lupus-predisposed cells as compared to disease-free cells.

-
20. A method comprising:
-
administering an agent to a lupus-affected or lupus-predisposed subject;
comparing expression profiles or protein activities of at least one gene in biological samples of the subject before and after said administering to determine if said agent modulates expression or protein activity of said at least one gene in the subject, wherein said at least one gene is differentially expressed in lupus-affected or lupus-predisposed kidney tissues as compared to disease-free kidney tissues.
