Herpesviridae glycoprotein B (gB) polypeptides comprising a modified ectodomain is stabilized in the prefusion state, enabling development of inhibitors and vaccines directed against these viral pathogens. Modifications to DI, DII, and DV subdomains are important to stabilization of gB in the prefusion state, and additional modifications result in a further improved stabilization of gB in the prefusion state. The gB can be derived from an Epstein Barr Virus (EBV), a Human Cytomegalovirus (CMV), a Human Herpesvirus 6 (HHV6), a Herpes Simplex Virus 1 (HSV1), or a Varicella Zoster Virus (VZV). Polypeptides, nucleic acid constructs, compositions, and methods of using same to elicit an immune response are described.

The present disclosure provides a vaccine composition that comprises an Epstein Barr Virus (EBV) polypeptide and a liposomal adjuvant, and methods of inducing an immune response to an Epstein Barr Virus (EBV) or methods of preventing infection of or reducing the likelihood of infection by an Epstein Barr Virus (EBV) using the compositions, or a combination of the EBV polypeptide and the liposomal adjuvant.

The invention provides methods and materials for the preparation of immune cells, including T cells engineered to express exogenous T cell receptors that target polypeptides associated with human leukocyte antigens. Embodiments of the invention include polynucleotides encoding T cell receptors that target human MEAF6 and SCAMP3 polypeptides, and engineered T cells transduced with these polynucleotides. Embodiments of the invention include polynucleotides encoding T cell receptors that target cytomegalovirus and Epstein Barr virus polypeptides, and engineered T cells transduced with these polynucleotides. Embodiments of the invention also include methods of making and using such polynucleotides and engineered T cells.

The present disclosure provides, a vaccine composition that comprises an Epstein Barr Virus (EBV) polypeptide and a squalene nanoemulsion (SNE) adjuvant, and methods of inducing an immune response to an Epstein Barr Virus (EBV) or methods of preventing infection of or reducing the likelihood of infection by an Epstein Barr Virus (EBV) using the compositions, or a combination of the EBV polypeptide and the SNE adjuvant.

Methods for the rapid detection of the presence or absence of Epstein Barr Virus (EBV) in a biological or non-biological sample are described. The methods can include performing an amplifying step, a hybridizing step, and a detecting step. Furthermore, primers and probes targeting EBV, and kits are provided that are designed for the detection of target regions of EBV. Also described are kits, reaction mixtures, and oligonucleotides (e.g., primer and probe) for the amplification and detection of EBV. Also described are primers and probes that detect different regions of EBV, and can be employed in a dual target assay for simultaneously detecting two different and non-overlapping target regions of EBV.

An isolated trifunctional bispecific antibody for use in a method of treating a patient suffering from a disease and / or disorder associated with reactivation of Epstein-Barr virus (EBV) in at least B cells and potentially other susceptible cells, such as susceptible epithelial cells, the method comprising: providing an autologous cell preparation of enriched B cells of the patient; incubating the enriched B cells with a trifunctional bispecific antibody for a period of time sufficient to establish a physical interaction between the trifunctional bispecific antibody and the enriched B cells to obtain an incubation mixture; transferring the incubation mixture obtained after incubation into the same patient, wherein the trifunctional bispecific antibody comprises: (a) a first binding arm binding to B cells via a B cell surface antigen; (b) a second binding arm binding to T cells via a T cell surface antigen; (c) an Fc part binding to Fc receptor positive cells. The invention also discloses a pharmaceutical composition comprising the isolated trifunctional bispecific antibody for use in treating a patient suffering from a disease and / or disorder associated with reactivation of EBV in B cells, and an ex vivo method for the preparation of the pharmaceutical composition.

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.

The present disclosure relates to T cells specific to Epstein-Barr virus (EBV), particularly rejuvenated T cells (rejT) that allow allogeneic administration.

A recombinant, humanized antibody or antibody fragment that is capable of at least partly preventing or inhibiting Epstein Barr Virus gp350 binding to a human cell. The antibody may be useful for passively immunizing humans against Epstein Barr Virus and / or treating or preventing Epstein Barr Virus-associated diseases, disorders or conditions. The antibody or antibody fragment may also be used to detect Epstein Barr Virus.
