A, MHC class II expression on OVA-stimulated MNECs cocultured with T cells (4 hours). B, CD4⁺ T-cell counts in cocultures with OVA-stimulated MNECs (24 hours). C and D, Fraction of CD69⁺/CD4⁺ (Fig 1, C) and CD44⁺/CD4⁺ (Fig 1, D) T cells after coculture with OVA-stimulated MNECs. E, INF-γ release in cocultures (24 hours). F, Cocultures with MNECs and T cells (both from sensitized mice) with anti–MHC class II antibodies (anti-MHC II). ∗P < .05, ∗∗P < .01, and ∗∗∗P < .001.
