This volume provides key methods and protocols from laboratories engaged in germinal centers (GC) research with the expectation of stimulating further research, and to aid scientists in the study of GC biology and pathology. Written in the highly successful Methods in Molecular Biology series format, chapters include ... 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.
