Biology Review

Paper Summary:

This paper discusses how antibodies and antigen serve to coat a foreign cell preventing the foreign cell from binding to other cells in the body. Binding of the antibodies and antigen to a toxin molecule prevents the foreign cell from accomplishing any of the tasks that it is intended to achieve. The paper further discusses how, never the less, this process is dependent on an effector mechanism in the complement system which has specific purposes. The compliment system serves as the overall protector while the antibodies and antigen direct the response of the compliment system which in turn destroys the foreign cells.

From the Paper:

"The integrity of the plasma membrane is essential for cellular survival. Could the immune system utilize this fact to destroy foreign cells that have invaded the body? How might cells of the immune system disrupt membranes of foreign cells? (Two hints: virtually all cells can secrete proteins, and some proteins form pores in membranes.) Antibodies and antigen serve to coat a foreign cell, preventing the foreign cell from binding to other cells in the body. Binding of the antibodies and antigen to a toxin molecule prevents the foreign cell from accomplishing any of the tasks that it is intended to achieve. Yet, this process is dependent on an effector mechanism in the complement system, which has specific purposes. The compliment system serves as the overall protector, while the antibodies and antigen direct the response of the compliment system, which in turn destroys the foreign cells."
