Web17 de jan. de 2024 · Primary Immune Response . Memory B-cells are long-lived plasma cells that are formed mainly in the germinal centres.. Firstly, during the primary immune response, naïve B-cells are activated by T-cells. after that, B-cells move to secondary lymphoid organs like the spleen and lymph nodes where they enter B-cell follicles or … WebThis binding activates helper T-cells. Activated helper T-cells are important because they spur B-cells into action. An activated T-cell attaches to a B-cell, causing it to make copies, or clones, of itself. Some of the B-cells become plasma cells capable of producing antibodies. Other B-cells become memory cells that get stored in your body.
