Abstract

Epidemiological evidence points to the inverse relationship between microbial exposure and the prevalence of allergic asthma and autoimmune diseases in Westernized countries.The molecular basis for this observation has not yet been completely delineated.Here we report that the administration of certain toll-like receptor (TLR) ligands, via the activation of innate immunity, induces high levels of indoleamine 2,3-dioxygenase (IDO), the rate-limiting enzyme of tryptophan catabolism in various organs.TLR9 ligand-induced pulmonary IDO activity inhibits Th2-driven experimental asthma.IDO activity expressed by resident lung cells rather than by pulmonary DCs suppressed lung inflammation and airway hyperreactivity.Our results provide a mechanistic insight into the various formulations of the hygiene hypothesis and underscore the notion that activation of innate immunity can inhibit adaptive Th cell responses.Nonstandard abbreviations used: airway hyperreactivity (AHR); 7-amino actinomycin D (7-AAD); bone marrow-derived DC (BMDC); enhanced pause (Penh); flagellin (Flag); IFN-α/β receptor (IFN-α/βR); IL-1β receptor (IL-1βR); immunostimulatory sequence oligodeoxynucleotide (ISS-ODN); indoleamine 2,3 dioxygenase (IDO); kynurenine (KYN); methacholine (MCh); 1-methyl-DL-tryptophan (M-trp); Pam3Cys-Ser-(Lys)-4-3HCl (P3C); poly I:C (pI:C); regulatory T cell (Treg); transgenic (Tg); tryptophan (trp).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
