How Do Helper T Cells Interact with Other Immune Cells?
Helper T cells interact with other immune cells through direct cell-to-cell contact and by secreting cytokines. For instance, Th1 cells release interferon-gamma to activate macrophages, while Th2 cells secrete IL-4 and IL-5 to assist B cells in antibody production. Treg cells help maintain immune tolerance by producing IL-10 and TGF-beta.
