Humoral response

• 1. A B - cell is triggered when the body is exposed to its matching antigen
• 2) The B - cells engulfs the antigen and digests it
• 3) Then it displays antigen fragments bound to its unique MHC molecules
• 4) The combination of MHC attracts the help of the mature matching T - cell
• 5) Cytokines secreted by the T - cell help the B - cell to multiply and mature into antibody by producing plasma cells
• 6) Once released into the blood, antibodies lock onto matching antigens. The antigen - antibody complex are then cleared by the complement cascade or by the liver and the spleen
