MIF-KO mice display attenuated cytokine production in skin-draining LN cells after EC OVA exposure. Production of Th2 cytokines (IL-4, IL-5, and IL-13) are compromised in the MIF-KO system despite supplementation with IL-2. Mice were EC exposed to OVA on day 0 and axillary LNs were harvested on day 4. LN cells were restimulated in vitro with OVA. After 48 hours, cytokine levels in culture supernatants were measured. WT (n=5), MIF-KO (n=5). Each panel is representative of three separate experiments. Statistical significance was determined using an unpaired Student’s t test or ANOVA. Error bars represent one standard deviation from the mean. *** p<0.001, **p<0.01, *p<0.05.
