Table 1. Expression of type I interferon and IL-6 in AEC co-cultured with MDDC.

	AEC	AEC(GM-CSF, IL-4)	AEC+MDDC(GM-CSF, IL-4)
IFNα2 mRNA	1.5±0.01	3.8±0.07 *	10.3±2.2 *
IFNβ mRNA	1.3±0.005	4.1±0.04 *	13.6±4.3 *
IL-6 (pg/ml)	<100	<100	26650±2200

AEC were cultured alone, in the presence or absence of GM-CSF + IL-4, or with MDDC. Following 5 days of culture RNA was extracted from sorted AEC and relative expression IFNα2 and IFNβ. *indicates p<0.05 relative to AEC alone (N = 6). IFNα protein was undetectable in culture supernatants. IL-6 protein data are from two experiments.
