Foxp3+ follicular regulatory T cells control the germinal center response

open access: yesNature Medicine, 2011
Follicular helper (TFH) cells provide crucial signals to germinal center B cells undergoing somatic hypermutation and selection that results in affinity maturation. Tight control of TFH numbers maintains self tolerance.

Invasion of the germinal centers

Cell, 2023
After vaccination or infection, long-lived germinal centers can produce antibodies with high affinity and specificity against pathogens. In this issue of Cell, de Carvalho et al. and Hägglöf et al. show that naive B cells can invade germinal centers, replacing B cells that entered early and changing features of antibody production.

Selection in the germinal center

Current Opinion in Immunology, 2020
Germinal centers (GCs) are well known for their important role in shaping the secondary B cell repertoire to generate antibodies capable of binding with high-affinity and specificity to foreign antigens. Somatic hypermutation of the Ig variable region genes in GC B cells represents a highly efficient mechanism for generating new antibody variants with ...

Germinal center development

Immunological Reviews, 1997
Summary: Using a set of surface markers Including igD and CD38, human tonsillar B cells were classified into discrete subpopulations. Molecular and functional analysis allowed us to identify: i) two sets of naive B cells (Bml and Bm2); ii) germinal center founder cells (Bm2′); iii) an obscure population of germinal center B cells, displaying a high ...

The germinal center reaction

Journal of Allergy and Clinical Immunology, 2010
The germinal center (GC) reaction is the basis of T-dependent humoral immunity against foreign pathogens and the ultimate expression of the adaptive immune response. GCs represent a unique collaboration between proliferating antigen-specific B cells, T follicular helper cells, and the specialized follicular dendritic cells that constitutively occupy ...

Germinal center reaction

Current Opinion in Hematology, 2001
The germinal center reaction is one critical outcome of helper T-cell-dependent antigen-specific B-cell responses. Germinal center reactions are the culmination of an orchestrated series of intercellular information exchanges discussed here as the serial synapsis model of adaptive immunity.
