MICROANATOMY

Detailed explanation-1: -Once B-cells are activated, they become plasma cells that produce antibodies in response to an antigen. Or they become memory cells that remember the antigen so your immune system can quickly identify and fight it in the future.

Detailed explanation-2: -B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections.

Detailed explanation-3: -Memory T cells are antigen-specific T cells that remain long-term after an infection has been eliminated. The memory T cells are quickly converted into large numbers of effector T cells upon reexposure to the specific invading antigen, thus providing a rapid response to past infection.

Detailed explanation-4: -The single unifying theme for all memory T cell subtypes is that they are long-lived and can quickly expand to large numbers of effector T cells upon re-exposure to their cognate antigen. By this mechanism they provide the immune system with “memory” against previously encountered pathogens.

Detailed explanation-5: -The T and B lymphocytes (T and B Cells) are involved in the acquired or antigen-specific immune response given that they are the only cells in the organism able to recognize and respond specifically to each antigenic epitope.
