Explanation:
Detailed explanation-1: -Dendritic cells initiate adaptive immune responses. Immature dendritic cells resident in infected tissues take up pathogens and their antigens by macropinocytosis and receptor-mediated phagocytosis.
Detailed explanation-2: -Once B cells and T cells are formed, a few of those cells will multiply and provide “memory” for your immune system. This allows your immune system to respond faster and more efficiently the next time you are exposed to the same antigen. In many cases, it will prevent you from getting sick.
