An activated T_C cell trying to kill off influenza infection in the lungs would: A) release pro-inflammatory cytokines throughout the entire lung B) produce monoclonal anti-influenza antibodies C) activate B cells to make influenza-specific plasma cells D) bind to the infected host cells, then release perforin and granzymes E) travel to the thymus and undergo positive selection

Question

Quizplus · Accepted Answer

An activated T_C cell is a cytotoxic T cell that functions to directly kill infected host cells. This is achieved by binding to the infected host cell and releasing perforin and granzymes, which induce cell death. Therefore, choice D is the best answer. Choices A, B, and C describe functions of other immune cells and are not directly related to the function of a cytotoxic T cell. Choice E is incorrect because activated T cells do not travel to the thymus, as they have already undergone selection in the thymus before being activated.
