The mechanism by which humans recognize self-cells from non–self (antigens)-cells is called:
A) Autoimmunity
B) Self-tolerance
C) Nonself anergy
D) Immunocompatibility
Ans: B
Feedback:
Self-tolerance is the mechanism that humans have for recognizing self-cells from non–self-cells. When tolerance fails, an autoimmune disorder can be the result. Immunocompatibility is how closely the cell surface markers of one human match with those of another human. Anergy is when T cells fail to respond to the presence of an antigen in the body.
