Number of activated CD4+ T cells (g) and frequency of type-2 cytokine and GMCSF producing lung CD4+ T cells (h) measured 8 days post-infection. Control group includes: WT mice (black circles), corn-oil treated Dock8fl/fl.CX3CR1-ERcre+ (white circles), and tamoxifen-treated Dock8fl/fl.CX3CR1-ERcre− (gold circles).
