Synchronous Germinal Center Onset Impacts the Efficiency of Antibody Responses

Frontiers in Immunology, 2019
The germinal center reaction is an important target for modulating antibody responses. Antibody production from germinal centers is regulated by a negative feedback mechanism termed antibody feedback.

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 ...

Germinal Center Optimization Algorithm

International Journal of Computational Intelligence Systems, 2018
Artificial immune systems are metaheuristic algorithms that mimic the adaptive capabilities of the immune system of vertebrates. Since the 1990s, they have become one of the main branches of computer intelligence.

Germinal centers and autoantibodies [PDF]

Immunology & Cell Biology, 2020
AbstractPreventing self‐reactive lymphocytes from participating in effector responses is fundamental to maintaining immunological self‐tolerance and circumventing autoimmunity. A range of complementary mechanisms are known to act upon the primary B‐ and T‐cell repertoires to this effect, eliminating or silencing lymphocytes expressing self‐reactive ...

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.

Expression of thyroglobulin on follicular dendritic cells of thyroid mucosa-associated lymphoid tissue (MALT) lymphoma [PDF]

, 2009
Reportedly, thyroid mucosa-associated lymphoid tissue (MALT) lymphoma is closely associated with Hashimoto's thyroiditis. However, it remains unknown which antigen is closely associated with thyroid MALT lymphoma.

Textbook Germinal Centers? [PDF]

The Journal of Immunology, 2004
AbstractModels 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.

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 ...

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.
