Quizplus · Accepted Answer

T_H2 cells, also known as T helper 2 (Th2) cells, are responsible for producing IL-4, which activates mast cells, basophils, and eosinophils for protection against extracellular pathogens, especially parasitic worms. Cytotoxic T lymphocytes and regulatory T lymphocytes have different functions and do not produce IL-4. T_H1 and T_H17 cells are not known immune cell types.
