Allergic response. Computer artwork showing the process that produces an allergic reaction. Antigens (blue),such as pollen,cause the release of cytokines (signalling chemicals) that stimulate B-lymphocyte white blood cells (large,round,upper right) to produce antibodies (Y-shaped). The antibodies travel in the blood stream and are picked up by mast cells (centre left),which use them to identify the antigens. When the antibodies come into contact with the antigens they bind to them,stimulating the mast cell to release histamine (yellow),which triggers the allergic reaction | |
