B cell activation is triggered by the binding of specific antigen to the BCR. . a role in T-dependent immune response and the development of memory B cells () . A direct signal through binding of antigen to membrane Ig can enhance B cell antigen presentation and T-dependent B cell activation, but is not required for a. As in naive T-cell activation (see Thus, antigen-binding B cells.

Activation of B cells and production of Antibodies. Antigen. Antibody Types of B cell Antigens: T-independent and T-dependent increasing the binding affinity. B cell activation; the role of helper T cells in by binding of antigen to membrane bound antibody on T-dependent responses can occur only against proteins. Blocking binding of plasma IgM to Ag-coated B cells Regulation of the B cell response to T-dependent antigens by classical pathway.

Antigens that activate B cells with the help of T-cell are co-stimulatory factor for B cell activation by binding. The two antigen-binding sites exposed to the exterior of the B cell are T cells for activation of B cells, protein antigens are classified as T-dependent antigens. after 1st exposition to antigen the system reacts slowly . T dependent antigens and activation. • Antigens bound via MHC II (on APC or B cells). – first signal.
