| | MedlinePlus Medical Encyclopedia: Immune response |
 | | Usually, the action of the immune response is desired. | | | Vaccination (immunization) is a way to trigger the immune response. | | | Acquired immunity is when the body is exposed to various antigens and builds a defense that is specific to that antigen. |

| | Immune System |
| | Parts of the immune system are antigen-specific (they recognize and act against particular antigens), systemic (not confined to the initial infection site, but work throughout the body), and have memory (recognize and mount an even stronger attack to the same antigen the next time). | | | The human immune system is a truly amazing constellation of responses to attacks from outside the body. | | | Parts of the immune system are changeable and can adapt to better attack the invading antigen. |

| | Cancer disarms immune stystem cells |
| | Whether the immune system even responds to cancer has been unclear and somewhat controversial, said Peter P. Lee, MD, a postdoctoral fellow in hematology and immunology and lead author of a paper published in the June issue of Nature Medicine. | | | The first step was to analyze blood samples from 11 patients with metastatic melanoma, in which the cancer had spread from its origin in the skin. | | | Using a speedy new method for analyzing immune system activity, a Stanford-led research team has discovered how the cancer manages to evade the normally watchful immune system. |
