On the other hand, the intensities of serum cytokine levels (Figure 4) indicated that Th1-related cytokines (IFN-γ, TNFα) and Th2-related cytokines (IL-4, IL-9) were relatively elevated in the remission phase compared to the acute phase, whereas the intensities of granulocyte-related cytokines (eotaxin, G-CSF, MCP-1, MIP-1b) were almost the same in the acute and remission phases of VKH disease patients. Here, IL9 is linked to Vogt-Koyanagi-Harada disease.
