MIF receptor (CD74) deficiency attenuates Th2 but not Th1 cytokine production in skin-draining LN cells after EC OVA exposure to a greater extent than does MIF deficiency. 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 and, after 48 hours, cytokine levels in culture supernatants were measured. WT: n=5, MIF-KO: n=5, CD74-KO n=5. Each panel is representative of three separate experiments. *** p<0.001, **p<0.01, *p<0.05.
