Reverse transcription-PCR analysis of interleukin-21 in the cells of spleen and draining lymph node in experimental autoimmune uveitis, recovery phase and control mice. mRNA of IL-21 in splenocytes and draining lymph node (DLN) cells of EAU, recovery phase mice, and control mice were extracted and measured through RT–PCR. A: IL-21 mRNA of DLN cells in EAU, recovery phase mice, and control mice. B: IL-21 mRNA of spleen cells in EAU, recovery phase mice, and control mice. C: The relative IL-21 mRNA levels were determined as the ratio of the IL-21 PCR product over the β-actin product. Data are presented as mean±standard deviation; n=6 per group.
