Abstract excerpt
Whether germinal centers (GC) with follicular dendritic cell (FDC) clusters are the essential sites for affinity maturation of immunoglobulin is still controversial. To re-evaluate the role of GC / FDC in affinity maturation and somatic mutation in a defined antigen system, lymphotoxin-alpha(- / -) and TNF receptor I(- / -) mice, lacking GC / FDC, were immunized with (4-hydroxy-3-nitrophenyl) acetyl-sheep RBC...
