WebFully developed germinal centers are polarized into a dark zone, which faces the T cell-rich zone toward the center of the lymph node, and a light zone, which is oriented toward the lymph node capsule. Germinal center B cells can be subdivided into centroblasts and centrocytes based on their morphologic features. Centroblasts are large cells ... WebGerminal centers are oligoclonal clusters of B cells responding to antigen, typically in T cell-dependent immune responses (Thorbecke et al., 1994 ). B cells undergo intense clonal expansion in germinal centers, where they ultimately differentiate into long-lived plasma cells or memory B cells.

WebGerminal 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 antibodies. … WebElements involved in the de novo formation of a germinal center, like antigen, T cells, and the mysterious germinal‐center‐precursor cell, are discussed.
