1 Der p 1 suppresses indoleamine 2, 3-dioxygenase in dendritic cells from house dust mite–sensitive patients with asthma  Kittipong Maneechotesuwan, MD, PhD, Valla Wamanuttajinda, BSc, Kanda Kasetsinsombat, MSc, Sukit Huabprasert, BA, Metha Yaikwawong, MD, Peter J. Barnes, DM, FRS, Adisak Wongkajornsilp, MD, PhD  Journal of Allergy and Clinical Immunology  Volume 123, Issue 1, Pages (January 2009) DOI: /j.jaci Copyright © 2009 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 Differential effect of Der p 1 on the expression and activity (A and B) of IDO in DCs. Protein levels of IDO (C and E), surface molecules, and intracellular cytokines (D) in DCs and TNF receptors on monocytes (F) were analyzed by fluorescence-activated cell sorting. One representative experiment of 3 is shown. Results are expressed as the means ± SDs. ∗P < .05; ∗∗P < .01.

6 Fig 2 Proliferative response of allergen-specific T-cell clones to Der p 1–pulsed DCs or their conditioned medium from HDM-sensitive, nonatopic patients with asthma and normal subjects (A), and to Der p 1–pulsed DCs or their conditioned medium from multiallergic subjects and subjects with cockroach allergy (B). Means ± SDs of 3 independent experiments are shown.

7 Fig 3 TH1/TH2 cytokine profiles (A and B) maintained IDO activity (C) and clonal T-cell proliferation (D) in HDM-sensitive and nonatopic DCs. An increase in regulatory T-cell subset (E) and its activity (F) was observed in the nonatopic condition. Means ± SDs of 3 independent experiments are shown.

8 Fig 4 Neutralization study using mAbs revealed the regulation of IDO activity in DCs was mediated through IL-4 and IFN-γ (A and B) with a corresponding action on clonal T-cell proliferation (C and D). Means ± SDs of 3 independent experiments are shown.
