High-affinity antibody responses develop in germinal centers (GCs). Recent advances reveal distinct cell states govern GC B cell selection, proliferation, and somatic hypermutation (SHM), offering new insights into immunity.
Area of Science:
- Immunology
- Molecular Biology
- Cell Biology
Background:
- Germinal centers (GCs) are crucial for developing protective antibody responses.
- Understanding GC dynamics is key to humoral immunity.
Purpose of the Study:
- To review recent advances in GC B cell dynamics.
- To present a new model of GC B cell function.
Main Methods:
- Review of recent scientific literature.
- Analysis of molecular and cellular dynamics within GCs.
Main Results:
- GC B cell function, selection, proliferation, and somatic hypermutation (SHM) occur in distinct cell states.
- A new model integrating these cell states has been proposed.
Conclusions:
- This new model offers novel perspectives on GC development.
- It provides opportunities to understand immunity in infectious, autoimmune, and neoplastic diseases.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
