WebAt the Roy Lab, I assisted in the development of a physiologically relevant antigen germinal center through the introduction of antigen-loaded … 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 persist for about 3 weeks following immunization, but after this, memory B blasts continue to proliferate in follicles throughout the months of T cell-dependent antibody responses. These cells are probably the source of plasma cells and memory cells required to maintain long-term antibody production and memory after the first 3 ... eascorp bankWebFeb 3, 2024 · Germinal centers (GCs) are microanatomical sites of B cell clonal expansion and antibody affinity maturation. Therein, B cells undergo the Darwinian process of somatic diversification and affinity-driven selection of immunoglobulins that produces the high-affinity antibodies essential for effective humoral immunity.

Using a set of surface markers including IgD and CD38, human tonsillar B cells were classified into discrete subpopulations.
