The germinal center (GC) is a dynamic microenvironment where antigen (Ag)-activated M cells rapidly expand and differentiate, generating plasma cells (PC) that produce high-affinity antibodies. freezing tonsillar cells section binding assay showed that CD9+ GC-B cells destined to the GC area of tonsillar cells significantly more than the CD9? GC-B cells did and that the… Continue reading The germinal center (GC) is a dynamic microenvironment where antigen (Ag)-activated
