  • 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.

  • Publication number: 20220193252
    Abstract: The invention is directed to the field of gene therapy, i.e. gene delivery into target cells, tissue, organ and organism, and more particularly to gene delivery via viral vectors. The inventors showed that it is possible by chemical coupling to modulate the coupling of a ligand in the surface of the capsid of AAV, for example AAV2 and AAV3b. In particular, the present invention relates to a recombinant Adeno-Associated Virus (rAAV) vector particle having at least one primary amino group contained in the capsid proteins, chemically coupled with at least one ligand L wherein coupling of said ligand L is implemented through a bond comprising a —CSNH— bond and an optionally substituted aromatic moiety. Particularly, the inventors tested the chemical coupling of mannose ligand on AAV2 for subretinally injection to rats.

  • Patent number: 11365257
    Abstract: The present invention relates to methods for promoting T cells response. The inventors examined the expression and function of CLEC-1 in human DCs and demonstrated for the first time a cell-surface expression. They investigated its functional role following triggering on orchestration of T-cell responses. The inventors showed in vitro and in vivo with CLEC-1 deficient rats and rat CLEC-1 Fc fusion protein that disruption of CLEC-1 signalling enhances in vitro Th17 activation and in vivo enhances T cell priming and Th17 and Th1 activation. In particular, the present invention relates to CLEC-1 antagonists for promoting T cells response in a subject in need thereof.

  • Publication number: 20220098264
    Abstract: Interleukin-34 is a cytokine that is involved in the differentiation and survival of macrophages, monocytes, and dendritic cells in response to inflammation. The involvement of IL-34 has been shown in areas as diverse as neuronal protection, autoimmune diseases, infection, cancer, and transplantation. Recent work has also demonstrated a new and possible therapeutic role for IL-34 as a Foxp3+ Treg-secreted cytokine mediator of transplant tolerance. New mutated IL-34 polypeptides have been generated, which can be used as agonists or antagonists.
