Humoral response

- The 'Humoral' refers to body fluids the antibodies travel in
- It occurs when a T-helper cell presents the antigen to the B-cells
- Don’t directly attack the foreign organism (compared to t-cells)
- Are activated by foreign antigens that are displayed by macrophages and dendritic cells.
- Each B-cell has a unique antibody embedded on its surface that is able to recognise one particular antigen
- Once the antibody binds to the antigen the organism or toxin is now harmless which allows the phagocytes to engulf the mass via phagocytosis
- After the infection is defeated memory B-cells stay in the lymphatic tissue which are able to produce antibodies specific to that certain foreign organism more rapidly if the pathogen should ever re-enter the body (secondary response)
- Antibodies are Immunoglobulins that are secreted by b-cells to fight the infection
- Those produced by particular B cells are particular to a foreign antigen which stimulated their production
