Amounts of IL-4 and IFN-γ (in pg/ml) Secreted In Vitro in Response to L. major Antigens

	IRF-2+/−		IRF-2−/−
	−LmAg	+LmAg	−LmAg	+LmAg
IL-4	<10	<10	<10	40 ± 9
IFN-γ	206 ± 98	2,790 ± 1,438	75 ± 11	88 ± 19

Amounts of IFN-γ and IL-4 secreted in response to L. major antigens (LmAg) by total popliteal LNCs of individual IRF-2^+/− and IRF-2^−/− mice taken 4 wk after infection with L. major. Data are shown as mean ± SD for three mice in each respective group and are representative of three independent experiments.
