Analyze kinetics, cell composition and proliferation of germinal center B cells in wt vs Ung-/- vs Aicda-/- vs Ung-/- Aicda-/- mice after immunization with model antigens.
The cytokine interleukin-21 (IL-21) is a pivotal T cell-derived signal crucial for germinal center (GC) responses, but the precise mechanisms by which IL-21 influences B cell function remain elusive.
Protective immunity to blood-stage malaria is attributed to Plasmodium-specific IgG and effector-memory T helper 1 (Th1) cells. However, mice lacking the costimulatory receptor CD28 (CD28KO) maintain
