Continuous Germinal Center Invasion Contributes to the Diversity of the Immune Response

open access: yesCell, 2022
Summary Antibody responses are characterized by increasing affinity and diversity over time. Affinity maturation occurs in germinal centers by a mechanism that involves repeated cycles of somatic mutation and selection.

Germinal Centers [PDF]

open access: yesAnnual Review of Immunology, 2012
Germinal centers (GCs) were described more than 125 years ago as compartments within secondary lymphoid organs that contained mitotic cells. Since then, it has become clear that this structure is the site of B cell clonal expansion, somatic hypermutation, and affinity-based selection, the combination of which results in the production of high-affinity ...

The magnitude of the germinal center B cell and T follicular helper cell response predicts long-lasting antibody titers to plague vaccination

open access: yesFrontiers in Immunology, 2022
The development of a safe and effective vaccine against Yersinia pestis, the causative organism for plague disease, remains an important global health priority.

Antibody Mediated Intercommunication of Germinal Centers

open access: yesCells, 2022
Antibody diversification and selection of B cells occur in dynamic structures called germinal centers (GCs). Passively administered soluble antibodies regulate the GC response by masking the antigen displayed on follicular dendritic cells (FDCs).

Tfh cells and the germinal center are required for memory B cell formation & humoral immunity after ChAdOx1 nCoV-19 vaccination

open access: yesCell Reports Medicine, 2022
Summary Emergence from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been facilitated by the rollout of effective vaccines. Successful vaccines generate high-affinity plasma blasts and long-lived protective memory B cells.

Analysis of immunophenotypic features in hyaline vascular type Castleman disease

open access: yesDiagnostic Pathology, 2023
Background Studies suggested that the immunophenotype of hyaline vascular type Castleman disease (HVCD) lacked characteristics, which was easy to be confused with other diseases. Methods From January 2010 to June 2022, 17 cases of HVCD were selected from

Germinal center reactions in tertiary lymphoid structures associate with neoantigen burden, humoral immunity and long-term survivorship in pancreatic cancer

open access: yesOncoimmunology, 2021
Pancreatic ductal adenocarcinoma (PDAC) has traditionally been thought of as an immunologically quiescent tumor type presumably because of a relatively low tumor mutational burden (TMB) and poor responses to checkpoint blockade therapy.

Dynamic Regulation of Tfh Selection During the Germinal Center Reaction

open access: yesNature, 2021
The germinal centre is a dynamic microenvironment in which B cells that express high-affinity antibody variants produced by somatic hypermutation are selected for clonal expansion by limiting the numbers of T follicular helper cells1,2.

Dynamic regulation of B cell Complement Signaling is Integral to Germinal Center Responses

open access: yesNature Immunology, 2021
Maturation of B cells within germinal centers (GCs) generates diversified B cell pools and high-affinity B cell antigen receptors (BCRs) for pathogen clearance.

Germinal Center and Extrafollicular B Cell Responses in vaccination, immunity and autoimmunity

open access: yesImmunity, 2020
Activated B cells participate in either extrafollicular (EF) or germinal center (GC) responses. Canonical responses are composed of a short wave of unmutated plasma cells arising from EF sites, followed by GC producing somatically mutated memory B cells (
