Overview and immunoglobulin response after VitD3-supplemented GP-SCIT treatment. (A) Outline of the SCIT protocol. (B) Outline of the treatment groups. (C) Serum total IgE (ng/mL) taken before SCIT (white bars, Pre1), before challenge (grey bars, Pre2), and after challenge (black bars, Post). (D) Serum GP-spIgE (Arbitrary Units (AU)/mL, Pre1, 2, Post). (E) Serum GP-spIgG1 (AU/mL, Pre1, 2, Post). (F) Serum GP-spIgG2a (AU/mL, Pre1, 2, Post). (G) Blocking activity plotted as ratio of GP-spIgG1/GP-spIgE in Pre2 sera. (H) Blocking activity plotted as ratio of GP-spIgG2a/GP-spIgE in Pre2 sera. (I) Fold induction of GP-spIgE after challenge (Post-sera/Pre2-sera). In Fig. 1C–F, values are expressed as mean ± SEM (n = 8). In Fig. 1G–I, values are expressed in Box-and-whiskers plots (min-max). NC, Negative Control, PBS challenged; PC, Positive Control, GP challenged; PCD, PC with VitD3 in SCIT (10 ng); 100, 100kSQ SCIT; 100D, 100kSQ SCIT with 10 ng VitD3. *P < 0.05, **P < 0.01, ***P < 0.001 compared to PC or PCD respectively (100 vs PC and 100D vs PCD), unless otherwise specified.
