This is a Summary of Interactions in an Immune Response

Pathogens have antigens that bind to specific B-cells which become stimulated by lymphokines, as a result the B-cells become activated and turn into plasma cells which make many anibodies that then flow into the bloodstream, or they turn into Memory B-cells. When a pathogen is trapped by a macrophage it becomes disassembled by the macrophage and the macrophage displays it's antigens to pre-killer T-cells which are also like the B-cells stimulated by lymphokines, resulting in activated Killer T-cells that destroy the pathogen- infected cells or become memory Killer T-cells. Macrophages also display the pathogens antigens to Helper T-cells which in turn become activated Helper T-cells and make many lymphokines which stimulate pre-Killer T-cells, B-cells and Helper T-cells which as a result make more lymphokines and memory Helper T-cells.
