Figure 3. Intratracheal transfer of Th2 cells does not restore eosinophil trafficking into the airways in STAT6-/- mice.
A) Representative flow cytometry of BAL cells stained for CD4 and KJ following intratracheal transfer of OVA-specific in vitro polarized Th2 lymphocytes and 3 OVA challenges (n = 6 mice per group, from 2 experiments). B) Number of CD4+ and KJ+ OVA-specific Th2 cells in the BAL of wild-type and STAT6-/- mice following intratracheal transfer of OVA-specific in vitro polarized Th2 lymphocytes and 3 OVA challenges (n = 6 mice per group, from 2 experiments). C) Number of eosinophils in the BAL of wild-type and STAT6-/-mice following intratracheal transfer of OVA-specific in vitro polarized Th2 lymphocytes and 3 OVA challenges (n = 6 mice per group, from 2 experiments). D) Percentage of CCR3+ cells in the granulocyte gate of cells isolated from blood of wild-type and STAT6-/- mice following intratracheal transfer of OVA-specific in vitro polarized Th2 lymphocytes and 3 OVA or PBS challenges (n = 3 mice per group, from 1 experiment). E) Lung chemokine RNA copies normalized to copies of GAPDH RNA in wild-type and STAT6-/- mice following intratracheal transfer of OVA-specific in vitro polarized Th2 lymphocytes and 3 OVA challenges (n = 6 mice per group, from 2 experiments).
