Cytokine concentration in BALf. The concentration of cytokines in BALf was measured by outsourcing to Linco by multiplexing technique in a luminometer. Data expressed here are mean ± SEM. n = 5/group. While all other Th2 cytokine levels were comparable to WT+OVA, IL-13 concentration was increased 2.7-fold over post-OVA WT values. Abbreviations used are: WT = wildtype, NOX = gp91phox-/-, DKO = gp91phox-MMP12 double knockout, WA = WT+alum, WO = WT+OVA, NOXA = gp91phox-/-+alum, NOXO = gp91phox-/-+OVA.
