We compared the expression levels of Th1–related cytokines (interleukin (IL)–2, interferons (IFN)–γ, and tumor necrosis factors (TNF)–α), and Th2–related cytokines (IL–4 and IL–10), in the OM of Pd–induced ICM and ACM mice to examine inflammation in allergic OM (Figure 4). The gene discussed is IL4; the disease is ocular melanoma.
