WebA B cell becomes activated when its receptor recognizes an antigen and binds to it. In most cases, however, B-cell activation is dependent on a second factor mentioned above—stimulation by an activated helper T cell. WebB cells have B cell receptors (BCRs) on their surface, which they use to bind to a specific protein. Once the B cells bind to this protein, called an antigen, they release antibodies …
WebB cells participate in a chemical response to antigens present in the body by producing specific antibodies that circulate throughout the body and bind with an antigen whenever it is encountered. This is known as the humoral immune response because it involves molecules secreted into the blood plasma, an acellular fluid or “humor.” WebAntigens are recognized by the host body by two distinct processes (1) by B cells and their surface antibodies (sIgM) and (2) by the T cell receptor on T cells. Although both B and …

WebForeign antigen binds B cell with appropriate antibody. 2. B cells become activated and differentiate into plasma and memory cells. 3. Low-affinity IgM is produced and secreted into serum 4. Isotype switching occurs. 5. Large quantities of IgG are produced and secreted into serum. 6. Plasma cells die.
Web-B-cells are activated by the binding of antigen to receptors on its cell surface which causes the cell to divide and proliferate. Some stimulated B-cells become plasma cells, which secrete antibodies. Others become long-lived memory B-cells which can be stimulated at a later time to differentiate into plasma cells.
