Question

Quizplus · Accepted Answer

Cytotoxic T cells are a type of T cell that can directly attack and kill other cells of the body, including those infected with viruses or other pathogens. They do not require the double recognition signal of both class I MHC and class II MHC on the target cell to function, nor do they self-destruct once the antigen has been neutralized. They also do not function mainly to stimulate the proliferation of other T cell populations.
