Anti-Dectin-2 monoclonal antibodies inhibited Der p 2-stimulated T-helper 2 cell cytokine production in monocyte-derived DC/CD14 PBMC co-culture, PBMCs were obtained from six patients with asthma with high level of anti-D. pteronyssinus IgE. Monocyte-derived DCs (MoDCs) and CD14 PBMCs were prepared as described in the Materials and Methods section. Der p 2 was added to the co-cultures of MoDCs and CD14 PBMC at a final concentration of 1 (a) or 3 (b) μg/mL. Anti-Dectin-2 monoclonal antibody (MoAb) 6A4G7 and 17A1D10 were added at a final concentration of 0.3, 1, or 3 μg/mL. IgG2a, at a final concentration of 3 μg/mL, was used as an isotype control. After second stimulation, the supernatant was harvested and IL-5 and IL-13 levels were measured by ELISA. Mann–Whitney U test was used to compare the percent inhibition of cytokine release between anti-Dectin-2 MoAb and IgG2a. * p < 0.05; ** p < 0.01; *** p < 0.005
