Suppose that an infectious agent, such as a virus or bacterium, had surface antigens identical to those displayed on the surface of human cells. Would the immune system be able to detect and destroy these agents? Why or why not?
What will be an ideal response?
No. Specific molecular markers on cell surfaces also play a role in the immune response. Each cell in the body carries recognition molecules that prevent the immune system from attacking our organs and tissues. These markers are encoded by a set of genes on chromosome 6 called the major histocompatibility complex (MHC).
