Provided is a method for diagnosing the prognosis and therapeutic effect for chemotherapy in patients with rheumatoid arthritis-associated lymphoproliferative disorder (RA-LPD), who have developed a lymphoproliferative disorder (LPD) during the treatment of rheumatoid arthritis (RA). This is a kit for diagnosing the prognosis and therapeutic effect for chemotherapy in rheumatic arthritis-associated lymphoproliferative disorder (RA-LPD) patients, who have developed LPD during RA treatment. The kit comprises: means for detecting an inositol 1,4,5-triphosphate receptor (ITPR) type 2 (ITPR2) gene mutation in a biological sample from a patient; and instructions for determining that the prognosis and therapeutic effect for chemotherapy are poor when an ITPR2 gene mutation is present in the biological sample from the patient. The LPD is diffuse large B-cell lymphoma (DLBCL). For the ITPR2 gene mutation, Chr12:rs26744460 is GT or GG. Use for the diagnosis of non-RA lymphoma patients is also possible.

Inventors have first investigated the impact of PIK3CA inhibition in NZBWF1 / J mice a model of lymphoproliferative disorders. They randomly assigned 30 females aged of 24 weeks to receive either vehicle (n=15) or alpelisib (n=15) during 4 weeks. At the time of sacrifice, alpelisib treated mice demonstrated significantly reduced spleen size. Flow cytometry analysis revealed that B cells were significantly reduced in alpelisib treated mice and CD8 cells count corrected. They then decided to explore the relevance of alpelisib in MRL / MpJ-Faslpr / J mice (referred here as MRL-lpr), another mouse model of lymphoproliferative disorder. These mice with homozygous Fas mutation usually develop severe lymphadenoproliferation. At the time of sacrifice. MRL-lpr mice treated with alpelisib demonstrated a reduction on their spleen and lymph node sizes. Flow cytometry analysis showed correction of B cells. T cells and other immune cells in peripheral blood mononuclear cells (PBMC), lymph nodes and spleen. The invention relates to a method for treating lymphoproliferative disorder in a subject in need thereof comprising a step of administering the subject with a therapeutically effective amount of a PIK3CA inhibitor.

The present invention relates to means and methods to prevent and / or treat Epstein-Barr virus (EBV) and EBV-induced diseases, such as EBV infection, infectious mononucleosis (IM), malignant or non-malignant post-transplant lymphoproliferative disorder (PTLD) and other EBV-associated diseases. In particular, the invention provides a SQAPLPCVL peptide that can be used in a treatment or a method of treatment to induce an EBV-specific immune response in a subject. The SQAPLPCVL can be used in a treatment or method of treatment as a vaccine against EBV and EBV-induced diseases. It is preferred herein that Epstein-Barr virus (EBV) and / or EBV-induced diseases are prevented.

The present invention relates to immunosuppressive compounds that deplete coronin 1 levels, in particular to coronin 1 promoter inhibitors. Accordingly, the present invention relates to a compound of formula (I), or a pharmaceutically acceptable salt, stereoisomer, diastereoisomer, enantiomer, polymorph, racemic mixture, or solvate thereof. The compound of formula (I) can be used as a medicament, in particular for inhibiting coronin 1 expression in the induction of immunosuppression or in the treatment and / or prevention of a disease or disorder selected from the group consisting of transplant rejection, autoimmune diseases, inflammatory diseases, infectious diseases, and lymphoproliferative disorders. The present invention further relates to a pharmaceutical composition comprising the compound of the present invention and a pharmaceutically acceptable carrier.

The present invention relates to a compound of formula (I) or pharmaceutically acceptable salts, stereoisomers, diastereoisomers, enantiomers, polymorphs, racemic mixtures, solvates or isomers and mixtures thereof. The invention also relates to a process for the stereoselective preparation of such compounds. The compounds of formula (I) are useful as medicaments, in particular for inhibiting crown protein 1 expression in the induction of immunosuppression or in the treatment and / or prevention of diseases or disorders selected from the group consisting of transplant rejection, autoimmune diseases, inflammatory diseases, infectious diseases and lymphoproliferative disorders. The present invention also relates to a vector comprising a crown protein 1 promoter element wherein the crown protein 1 promoter element starts directly upstream of the transcription start site (TSS) of the crown protein 1 gene and spans a sequence segment of at least about 700 bp in the genome in the vertebrate genome. The invention also relates to a method for identifying immunomodulatory compounds that alter the activity of the crown protein 1 promoter using said vector. The invention also relates to BRD3 as an upstream target responsible for driving crown protein-1 expression and activity in immune cells, and to compounds that selectively target the bromodomain of BRD3 and thereby deplete crown protein 1 levels, in particular compounds of formula (I). # imgabs0 #

The present invention relates to means and methods for combating myeloproliferative disorders or lymphoproliferative disorders. The present invention provides human AML-specific binding compounds capable of binding to a cell surface component of AML cells. Therapeutic applications of the binding compounds against AML are also contemplated.

The present invention provides a computer implemented method for predicting the risk of posttransplant lymphoproliferative disorder as well as a computer implemented method for simultaneous predicting the risk of posttransplant lymphoproliferative disorder and differentiation of Epstein Barr Virus (EBV)-positive from EBV-negative patients in posttransplant lymphoproliferative disorder and associated systems. The method for predicting the risk of posttransplant lymphoproliferative disorder PTLD, comprises the following steps: receiving information representative for expression level of biomarkers, acquired from a sample to be assessed, said biomarkers being at least three selected from the group comprising HSPA6, CD300A, IFITM1, SHFL, HMGB1, TMEM163, ELL3, GRHPR, GMDS, GALNT10, IRF1-AS1, IFIT5, MLLT3, KIR2DL4, CD1C, SP3, SLC6A16, COP1, classifying said information representative for expression level of said at least three biomarkers, outputting the classification results, said results being indicative of whether the assessed sample belongs to one of two classes: PTLD or non-PTLD patient. The present invention provides further biomarkers for predicting, diagnosing and differentiating of posttransplant lymphoproliferative disorders and use thereof.
