AS2863619 (30 mg/kg; oral administration; daily; for 2 weeks; mice) treatment after sensitization with 2,4-dinitrofluorobenzene (DNFB) dampens the degree of the secondary response, with milder infiltration of inflammatory cells into the skin and decreases ratios of interferon-γ⁺ (IFN-γ⁺) cells in a skin contact hypersensitivity model, when compared with vehicle-treated control mice. T_reg depletion before the elicitation of the secondary response abolishes AS2863619-induced suppression. KLRG1⁺ Foxp3⁺ T cells are specifically increased in DNFB sensitized AS2863619-treated mice^[1].
