Frequency of cytokine-positive T cells in LPS-treated Ch-RMs. Cytokine-positive T cells were grouped into three categories: IFN-γ⁺TNF-α⁺IL-2⁺ 3-function cells (filled squares), 2-function cells (filled triangles) expressing two cytokines, and 1-function cells expressing only IFN-γ, TNF-α, or IL-2 (filled circles).
