Immune System

Paper Summary:

This paper explains that the immune system generates numerous unusual kinds of immune reactions. For example, the body annihilates eukaryotic cells having or bearing foreign cell-surface antigens. These include cancer cells, whose cell-surface antigens are distorted when a normal cell is genetically changed into a cancer cell. The antigen-bearing cell may be eaten by macrophages or killed by killer cells, which are specialized to destroy abnormal body cells. The paper examines how the immune system functions, looking at physiological processes such as cellular immunity and humoral immunity.

From the Paper:

"Humoral immunity is best explained as if the virus has not yet invaded a body cell, it may be surfaced by antibody molecules that may have been secreted into the body fluids by B cells. The virus-antibody is then eaten and destroyed by a phagocyte."
