  • Patent number: 11479817
    Abstract: The present invention relates to a method for discriminating an operationally tolerant (TOL) subject from a non-operationally tolerant (STA) subject, comprising the following steps: i) establishing a composite score of tolerance (cSoT) with the expression levels of six genes in a biological sample obtained from said subject and two clinical parameters; wherein said six genes are ID3, AKR1C3, CD40, CTLA4, TCL1A and MZB1, and wherein said cSoT is established by the following formula: cSoT = ? i n ? = ? i × Exprs + ? test ? ? time × age test ? ? time + ? trans ? ? time × age trans ? ? time + intercept - scaling ? ? coefficient ii) comparing this cSoT with a predetermined reference value; and iii) concluding that the subject is TOL when the cSoT is higher than the predetermined reference value or concluding that the subject is STA when the cSoT is lower than the predetermined reference value.

  • Patent number: 11421277
    Abstract: The present invention relates to a method for predicting the risk of having the CLAD in a subject by measuring the expression level of TCL1A in a biological sample obtained from said subject. Inventors have used a large-scale gene expression profiling of whole blood cells to identify early biomarkers of BOS. Microarray experiments performed from 80 patients (40 stable (STA) and 40 BOS) identified 47 genes differentially expressed between STA and BOS recipients. An independent set of patients (13 STA, 11 BOS) was then used for external validation by qPCR. T-cell leukemia/lymphoma protein 1A (TCL1A) gene was identified and validated as a predictive marker of BOS more than 6 months before diagnosis with area under curve of 0.77. Accordingly, the invention relates to a method for predicting the risk of having the chronic lung allograft dysfunction (CLAD) and to a method for preventing the risk of having CLAD by administering immunosuppressive drugs.
