Summary: ENKTCL is an aggressive lymphoma associated with EBV infection, characterized by activation of the JAK-STAT pathway and mutations in genes like BCOR, DDX3X and TP53. Differences in EBV strains and LMP1 variants among populations provide insights into the pathogenesis and genetics of ENKTCL. The genetic landscape of ENKTCL highlights mechanisms of lymphomagenesis and potential therapeutic targets.

Summary: Post-transplant lymphoproliferative disorder (PTLD) is a serious complication of solid organ transplantation, associated with Epstein-Barr virus (EBV) infection. This study found that miR-194 and several other miRs were significantly decreased in the tumors and circulation of PTLD patients, which may be associated with EBV. These findings suggest the importance of studying the diagnostic and therapeutic potential of miRs in PTLD.

Summary: Natural killer/T-cell lymphoma (NKTCL) is an incurable aggressive T-cell lymphoma closely correlated with Epstein-Barr virus (EBV) infection. T-cell dysfunction and accumulation of inhibitory cell components were observed in NKTCL patients, including higher frequencies of inhibitory T regulatory cells (Tregs) and myeloid-derived suppressor cells (MDSCs), altered T-cell distribution, higher expression levels of multiple surface inhibitory receptors (IRs) in T cells, reduced T-cell proliferation and interferon-gamma production, lower number of EBV-specific cytotoxic cells with upregulated IRs and decreased effector cytokine secretion. Additionally, NKTCL cells induced T-cell exhaustion phenotypes, generation of Tregs and MDSCs in normal PBMCs.

Summary: The Epstein-Barr virus (EBV) encoded miRNA miR-BART11-3p promotes cell proliferation, migration, and invasion in gastric cancer (GC) by targeting DUSP6 and dysregulating the MAPK pathway. Restoring DUSP6 expression reverses the tumor-promoting effects of miR-BART11-3p, and blocking ERK phosphorylation inhibits the effects of miR-BART11-3p-expressing cells. These findings provide new insights into tumorigenesis in EBV-associated gastric cancer (EBVaGC) and potential therapeutic strategies.

Summary: The Epstein-Barr virus is common in humans and can lead to lymphoproliferative diseases which may develop into lymphoma. The immune system plays a role in monitoring EBV+ B cells to prevent tumor formation.

Summary: (English Summary)
This study compared the prognosis of patients with AITL or PTCL-NOS by assessing EBV infection using two different methods. The results showed that EBV infection negatively affected the clinical outcomes of TCL patients, and hematopoietic stem cell transplantation was found to be an effective treatment for EBV-associated lymphomas.

Summary: This study reveals that the lipid metabolism of lymphoma-derived extracellular vesicles (EVs) is enhanced by secreted phospholipase A(2) (sPLA(2)), leading to its pro-tumorigenic action. This study highlights the non-canonical mechanistic action of EVs as an extracellular hydrolytic platform of sPLA(2).

Summary: The study found that the prevalence of EBV in Hodgkin lymphoma (HL) diagnosed in the Butaro Cancer Center of Excellence in Rwanda is 54%, with detection in all classical subtypes. In non-Hodgkin lymphoma (NHL), the EBV prevalence is 9%, with Burkitt lymphoma in B-cell NHL having the highest detection rate of EBV.

Summary: Recognition of antigens by the B cell receptor can lead to reactivation of Epstein-Barr virus and certain miRNAs, like miR-141, play a role in dampening this reactivation. Both host and viral miRNAs can modulate the lytic cycle of EBV, with targets including B cell transcription factors and regulators of immediate-early genes. The study identifies FOXO3 as a key player commonly suppressed by these miRNAs, impacting the progression of the lytic cycle.

Summary: In this study, we describe an unusual spontaneous lytic phenotype in EBV strains isolated from Kenyan endemic Burkitt lymphoma patients. These findings provide insight into viral and host factors involved in this process and the potential contribution of promiscuous lytic activity to the formation of EBV-associated diseases.

Summary: This study reports two cases of nodal T follicular helper cell lymphoma (nTFHL) showing Epstein-Barr virus (EBV) positivity in the neoplastic cells, as well as unique gene mutations and poor prognosis. This finding expands the currently recognized spectrum of EBV-positive lymphomas to include rare cases of nTFHL.

Summary: Solid organ transplant is a life-saving therapy for children with end-stage organ diseases, but a significant proportion of recipients experience acute rejection. This study analyzed the immune composition of pediatric solid organ transplant recipients using high-dimensional mass cytometry, and found that the type of organ transplant strongly influences the post-transplant immune profile. Changes in the proportion of different T cell subpopulations are associated with graft health. These findings provide a basis for further understanding and developing new immunosuppressive agents.
