Immune Response Antibody 5
ANTIBODY RESPONSE IMAGE: in the antibody (or humoral) arm of the the adaptive (acquired) immune response, the destruction of invaders is done by antibodies (immunolglobulins), shown as brick red "Y" shaped molecules at right of picture. Invading microorganisms are shown at top as golden ovoids. They are engulfed (phagocytosed) by a macrophage (green cell at top). The macrophage then presents antigens to a (purple) Helper T-Cell which in turn activates a B-Cell causing it to divide and differentiate into Plasma Cells (large bluish cells at lower left). Plasma cells have a great deal of rough endoplasmic reticulum and are devoted to protein synthesis (of antibodies). The antibodies that are released lock onto their corresponding antigens and lead to the inactivation or destruction of the invader. A dendritic cell is shown at upper left.
