T-cell activation and cytokine production are not affected by C5 and FcRγ deficiency in K/BxN mice. (a) The plots depict cell surface expression of CD44 and CD62L on CD3⁺ CD4⁺ Vβ6⁺-gated splenocytes from the indicated mice. (b) Intracellular expression of the cytokines interleukin-17 (IL-17) and interferon-gamma (IFNγ) was detected in CD3⁺ CD4⁺ Vβ6⁺ splenocytes from the indicated mice. Vβ6 is the TCRβ chain encoded by the KRN TCR transgene. Data are representative of two to six mice per group in three independent experiments. TCR, T-cell receptor.
