The pharmacology instructor is discussing the histocompatibility of the cell. What is the importance of a cell's histocompatibility antigen?
A) It reproduces cells when other cells die.
B) It recognizes cells as self-cells that belong in the body.
C) The antigen produces antibodies to viral invaders.
D) The antigen stimulates the production of white blood cells.
B
Feedback:
The histocompatibility antigens are proteins that are seen on the top of the cell membrane. T cells use these antigens as the identifying proteins that identify a cell as a self-cell. If these antigens are not present on a cell membrane, the T cells will destroy that cell, determining that it is foreign. The histocompatibility antigens are not involved in reproduction. They do not produce antibodies nor do they stimulate white blood cell production.
