Critical role of SHP2 (PTPN11) signaling in germinal center-derived lymphoma

Haematologica, 2014
Germinal center lymphoma is a heterogeneous human lymphoma entity. Here we report that constitutive activity of SHP2 (PTPN11) and its downstream kinase ERK is essential for the viability of germinal center lymphoma cells and disease progression ...

Origin and pathogenesis of nodular lymphocyte–predominant Hodgkin lymphoma as revealed by global gene expression analysis [PDF]

, 2008
The pathogenesis of nodular lymphocyte–predominant Hodgkin lymphoma (NLPHL) and its relationship to other lymphomas are largely unknown. This is partly because of the technical challenge of analyzing its rare neoplastic lymphocytic and histiocytic (L&H ...

Coupled Antigen and BLIMP1 Asymmetric Division With a Large Segregation Between Daughter Cells Recapitulates the Temporal Transition From Memory B Cells to Plasma Cells and a DZ-to-LZ Ratio in the Germinal Center

Frontiers in Immunology, 2021
Memory B cells and antibody-secreting plasma cells are generated within germinal centers during affinity maturation in which B-cell proliferation, selection, differentiation, and self-renewal play important roles.

Suppression of signal transducer and activator of transcription 3-dependent B lymphocyte terminal differentiation by BCL-6 [PDF]

, 2000
Lymphocytes usually differentiate into effector cells within days after antigen exposure, except in germinal centers where terminal differentiation is delayed while somatic hypermutation creates high-affinity antibody mutants. Here we investigate whether

Amount of antigen, T follicular helper cells and affinity of founder cells shape the diversity of germinal center B cells: A computational study

Frontiers in Immunology, 2023
A variety of B cell clones seed the germinal centers, where a selection stringency expands the fitter clones to generate higher affinity antibodies. However, recent experiments suggest that germinal centers often retain a diverse set of B cell clones ...

Textbook Germinal Centers? [PDF]

The Journal of Immunology, 2004
Abstract Models for the development and function of germinal centers (GCs) have been so widely discussed in the original literature that they now appear in immunology textbooks. Unfortunately, many of the tenets of these models have not yet been subjected to adequate experimental scrutiny. Indeed, recent studies have called several of

Chemokine microenvironment in primary central nervous system lymphoma [PDF]

, 2010
Primary central nervous system lymphomas (PCNSL) are aggressive extranodal malignancies confined to the central nervous system (CNS), mostly of diffuse large B cell histotype.

PHGDH is required for germinal center formation and is a therapeutic target in MYC-driven lymphoma

The Journal of Clinical Investigation, 2022
The synthesis of serine from glucose is a key metabolic pathway supporting cellular proliferation in healthy and malignant cells. Despite this, the role that this aspect of metabolism plays in germinal center biology and pathology is not known.

Correlation between Germinal Center Differentiation and Double/Triple Hit Score in the Classification of Diffuse Large B Cell Non-Hodgkin Lymphoma: A Clinicopathological Approach

Asian Pacific Journal of Cancer Care, 2023
Background: Diffuse large B cell lymphoma (DLBCL) is considered the most common type of non-Hodgkin lymphoma. The global incidence of DLBCL has been doubled in the past decades, highlighting the need for more effective treatment regimens.

Antigen-driven clonal proliferation of B cells within the target tissue of an autoimmune disease: the salivary glands of patients with Sjögren's syndrome [PDF]

, 1998
Structures resembling germinal centers are seen in the salivary glands of patients with Sjögren's syndrome, but it is not known whether the microenvironment of these cell clusters is sufficient for the induction of a germinal center response.
