Question

An autoimmune disease represents a loss of
A)T helper cells.
B)B cells.
C)tolerance to self-antigens.
D)antigen-presenting cells.
E)mechanisms for antibody production.

Accepted Answer

An autoimmune disease occurs when the immune system attacks and damages the body's own tissues, indicating a loss of tolerance to self-antigens. The immune system normally learns to recognize and not attack the body's own cells through a process of self-tolerance. When this process breaks down due to genetic or environmental factors, autoimmune diseases can arise. T helper cells, B cells, antigen-presenting cells, and mechanisms for antibody production are all components of the immune system that can contribute to autoimmune responses, but they are not necessarily lost in autoimmune diseases.
