Show Answers

Promotes cell-mediated immune defenseStimulates antibody-mediated immunityActivates cytotoxic T lymphocyte responseDoes not initiate any immune response

TH2 cells mainly promote humoral immunity by helping B cells produce antibodies, whereas cell-mediated immunity involves other T-helper subsets like TH1. Therefore, TH2 cells are key in stimulating antibody-based immune responses.
