Quizplus · Accepted Answer

Cytokines released by TH1 cells, specifically interferon-gamma (IFN-γ), activate CD8⁺ cells and induce them to differentiate into CTLs (cytotoxic T lymphocytes), which can then target and kill infected cells. TH1 cells also release other cytokines, such as interleukin-2 (IL-2) and tumor necrosis factor-alpha (TNF-α), which help to activate and mobilize the immune system to fight infections.
