Aspects of the present invention include methods for determining a transplant category of a subject having a transplant. Common mechanisms of rejection injury are uncovered across different tissue transplants, and provide a means to understand rational drug design. Various sources of tissues are examined form the patient for understanding AR mechanism (graft biopsy), as well as monitoring by minimal invasive means (blood) or non-invasive means (urine for the kidney allograft). For biomarker discovery different categories of markers are examined such as genes, proteins, peptides and antibodies. These biomarkers can help determine the subject's transplant category (e.g., acute allograft rejection (AR), stable allograft (STA), BK viremia, BK nephritis, drug toxicity or chronic allograft injury (CAI), and the like). Also provided are compositions, systems, kits and computer program products that find use in practicing the subject methods. The methods and compositions find use in a variety of applications.

Protein and gene biomarkers for rejection of organ transplants

Methods are provided for monitoring a subject having a graft for an acute rejection (AR) response, e.g., to predict, to diagnose, and/or to characterize an AR response. In practicing the subject methods, the expression level of at least one gene in a sample from the subject, e.g., a blood or biopsy sample, is evaluated, e.g., at the nucleic acid and/or protein level, to monitor the subject. Also provided are compositions, systems, kits and computer program products that find use in practicing the subject methods.

Biomarker panel for diagnosis and prediction of graft rejection

Methods are provided for determining whether a subject has a graft tolerant phenotype. In practicing the subject methods, the expression level of one or more gene in a sample from the subject, e.g., a blood sample, is assayed to obtain a gene expression result, where the gene expression result includes a result for a biomarker of graft tolerance. The obtained gene expression result is then employed to determine whether the subject has a graft tolerant phenotype. Also provided are compositions, systems and kits that find use in practicing the subject methods. The methods and compositions find use in a variety of applications, including the determination of an immunosuppressive therapy regimen.

Biomarkers for determining an allograft tolerant phenotype

Provided herein are methods and compositions for the prediction and treatment of focal segmental glomerulosclerosis and other proteinuric renal diseases such as native FSGS, minimal change disease, glomerular nephritis, membrano-proliferative glomerular nephritis (membranous), or IgA glomerular nephritis (membranous).

Methods and compositions for the prediction and treatment of focal segmental glomerulosclerosis

Methods are provided for evaluating a subject for graft survival, e.g., in terms of predicting graft survival, identifying the presence of a deleterious graft condition, such as CAN and DT, identifying the severity and class of acute rejection, etc, in a subject are provided. In practicing the subject methods, the expression of at least one gene in a sample from the subject, e.g., a blood or biopsy sample, is assayed, e.g., at the nucleic acid and/or protein level, to evaluate the subject. Also provided are compositions, systems and kits that find use in practicing the subject methods. The methods and compositions find use in a variety of applications.

Methods and compositions for evaluating graft survival in a solid organ transplant recipient

Methods are provided for determining whether a subject has a graft tolerant phenotype. In practicing the subject methods, the expression of at least 5 genes in a sample from the subject, e.g., a blood sample, is assayed to obtain a gene expression result for the at least 5 genes. The obtained gene expression result for the at least 5 genes is then employed to determine whether the subject has a graft tolerant phenotype. Also provided are compositions, systems and kits that find use in practicing the subject methods. The methods and compositions find use in a variety of applications, including the determination of an immunosuppressive therapy regimen.

Methods and compositions for determining a graft tolerant phenotype in a subject

Aspects of the present invention include methods for diagnosing and monitoring IgAN in a subject. In practicing one aspect of the subject methods, a sample from a subject is analyzed for the presence of one or more specific autoantibodies to determine the IgAN phenotype of the subject. Also provided are compositions, systems, kits and computer program products that find use in practicing the subject methods. The methods and compositions find use in a variety of applications.

Autoantibody biomarkers for IGA nephropathy

Methods are provided for determining whether a subject has a graft tolerant phenotype. In practicing the subject methods, the expression of at least one gene in a sample from the subject, e.g., a blood sample, is assayed to obtain an expression evaluation for the at least one gene. The obtained expression evaluation is then employed to determine whether the subject has a graft tolerant phenotype. Also provides are compositions, systems and kits that find use in practicing the subject methods. The methods and compositions find use in a variety of applications, including the determination of an immunosuppressive therapy regimen.
