The T cells secrete the lymphoid factors to stimulate the B cells to proliferate and differentiate to produce plasma cells and memory B cells; memory T cells are also produced in the cellular immunity. When a second infection with the same protein occurs, the memory cells can directly proliferate and differentiate into plasma cells (in humoral immunity), and produce the combination of the protein and the protein. This process is faster and more intense than the initial immune response. In cellular immunity, memory T cells can also quickly respond to an immune response to an vaccine.
