In contrast, expression of Th1 related genes including interferon γ (Ifng) and interleukin 12A (Il12a) and of Th2 associated genes including interleukin 4 (Il4), interleukin 10 (Il10), chemokine ligand 11 (eotaxin 1; Ccl11) and its corresponding chemokine receptor 3 (Ccr3) was significantly elevated only in the skin of mice with allergen-induced dermatitis (Table 2). The gene discussed is CCR3; the disease is dermatitis.
