Non-Hodgkin's lymphomas (NHLs) are malignant neoplasms which are clinically and biologically diverse. Their incidence is constantly increasing and despite treatment advances, there is a need for novel targeted therapies. Here, we identified Lectin-like transcript 1 (LLT1) as a biomarker of germinal center (GC)-derived B-cell NHLs. LLT1 identifies GC B cells in reactive tonsils and lymph nodes and its expression is maintained in B-cell NHLs which derive from GC, including Burkitt lymphoma (BL), follicular lymphoma (FL), and GC-derived diffuse large B-cell lymphoma (DLBCL). We further show that LLT1 expression by tumors dampens natural killer (NK) cell functions following interaction with its receptor CD161, uncovering a potential immune escape mechanism. Our results pinpoint LLT1 as a novel biomarker of GC-derived B-cell NHLs and as a candidate target for innovative immunotherapies.

Febrile neutropenia (FN) is one of the most important clinical signs of infection, especially for older patients with indolent B cell non-Hodgkin lymphomas (iBC-NHLs) receiving frontline immune-chemotherapy with bendamustine-rituximab (BR). Data on the optimal strategy for infection prophylaxis from the start of chemotherapy until 1 month after the last cycle is scanty in this setting of patients, and for this reason, we carried out a multicentric retrospective study on vigorous primary anti-infectious prophylaxis consisting of lipegfilgrastim, trimethoprim-sulfamethoxazole, and acyclovir. From January 2017 to January 2022, 200 patients met the inclusion criteria and were enrolled in the final analysis.

CD20 is a tetraspan membrane-bound protein vital for the development, activation, and differentiation of human B-cells. Non-Hodgkin lymphoma (NHL) is the most common hematological cancer in people living with (PLWH), and most B-cell NHLs express CD20. Extracellular vesicles (EVs) are nanosized vesicles released by cells into the extracellular environment.

EZH-2 overexpression or mutation is associated with various cancers, and there is a substantial academic literature on the role of EZH-2 and its mutant alleles in the pathogenesis of B-cell non-Hodgkin lymphomas (NHLs). The objective of the study was to examine the expression of EZH-2 in patients with low-grade NHL and to assess the effect of this expression on prognosis. The study included 140 pathologically diagnosed indolent NHL cases that met the established inclusion and exclusion criteria.

Non-Hodgkin lymphomas (NHLs) encompass a diverse group of neoplasms arising from the clonal proliferation of B-cell progenitors, T-cell progenitors, mature B-cells, mature T-cells, and natural killer (NK) cells. These malignancies account for over 90% of lymphoid neoplasms. The link between the gut microbiome and neoplasms has been extensively studied in recent years.

Purpose: Barriers to health care access may contribute to the poorer survival of Black patients with Non-Hodgkin Lymphoma (NHL) than their White counterparts in the U.S. general population.
