If a T Cell is Exposed to a "Hidden" Antigen

Question

If a T cell is exposed to a "hidden" antigen, what kind of immune reaction will result?
A) an autoimmune disease
B) a delayed hypersensitivity reaction
C) a cytotoxic hypersensitivity reaction

Accepted Answer

When T cells are exposed to "hidden" antigens, which are normally sequestered from the immune system, it can lead to an autoimmune response as the immune system mistakenly attacks the body's own tissues.
