The aim of the study is to explore the possibility to identify, at an early stage after a renal graft and from blood samples collected within first months after graft, a predictive transcriptional profile of long term occurence of graft operational tolerance or chronic rejection.
The aim of the study is to determine an early transcriptional profile of chronic rejection in the transcriptome of mononuclear blood cells. Validation and predictivity of transcriptional analysis will be based on graft function and graft histology one year after transplantation.The other aim is to determine an early transcriptional profile of operational tolerance in the same patients using a DNA chip dedicated including two lists of genes discriminating tolerant patients who are stopped immunosuppressant treatment for over a year.
To allow statistical analysis of 100 patients followed one year after graft, patients not assessable at one year due to early termination of study will be replaced.

|Actual Study Completion Date :||May 2011|
Patients aged 18 to 65 years old receiving a first cadaveric renal graft.
Biological: DNA chip
One biopsy is realized before graft, another biopsy is realized one year after graft and a blood sample is collected 3 months after graft to realize DNA chip. Blood samples are also collected at day 0, day 1, month 3, month 6 and month 12 to analyze biochemistry, proteinuria, haematology, creatinine clearance and immunology at day 0, month 3 and month 12.
- Transcriptional profile (exhaustive DNAchip) on the blood at 3 months post transplantation. [ Time Frame: 3 months ]
- Correlation of the transcriptional profile at 3 months after transplantation with histological features of the kidney graft at one year of follow-up. [ Time Frame: One year ]
