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. 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 ...
