Cytokines produced by th1
WebTh1 cells are characterized by production of interferon-γ (IFN-γ) and induce cell-mediated immunity against intracellular pathogens, while Th2 cells produce interleukin-4 (IL-4) and stimulate humoral immunity against parasitic helminths. This paradigm was maintained until 2005, when a third T-cell subset, known as Th17, was identified (2, 3). WebThese two subsets of T(H) cells exhibit helper function in different ways and can be distinguished by the patterns of cytokines they synthesize. Support protocols describe a micromanipulation method for cloning T cells and a roadmap for using protocols published elsewhere in this series to assess cytokine production by T cell clones and lines.
