Cell Division speeds up as part of antibody selection. Mechanisms that favor selection of B cells capable of producing antibodies with highest affinity for that invader. “2 of the mechanisms that allow high affinity B cells to overwhelm the others,” says Alex Gitlin.
During an infection, B + other immune cells form germinal centers in spleen and lymph nodes, where B cells evolve in a Darwinian-like fashion...
