Abstract

Adaptive features of innate immunity, recently described as “trained immunity,” have been documented in plants, invertebrate animals, and mice, but not yet in humans. Here we show that bacille Calmette-Guérin (BCG) vaccination in healthy volunteers led not only to a four- to sevenfold increase in the production of IFN-γ, but also to a twofold enhanced release of monocyte-derived cytokines, such as TNF and IL-1β, in response to unrelated bacterial and fungal pathogens. The enhanced function of circulating monocytes persisted for at least 3 mo after vaccination and was accompanied by increased expression of activation markers such as CD11b and Toll-like receptor 4. These training effects were induced through the NOD2 receptor and mediated by increased histone 3 lysine 4 trimethylation. In experimental studies, BCG vaccination induced T- and B-lymphocyte–independent protection of severe combined immunodeficiency SCID mice from disseminated candidiasis (100% survival in BCG-vaccinated mice vs. 30% in control mice). In conclusion, BCG induces trained immunity and nonspecific protection from infections through epigenetic reprogramming of innate immune cells.

  • NOD2 stimulation by MDP and its analogs can alter host immunity through multiple pathways, including macrophage activation for tumor clearance, epigenetic reprogramming of monocytes, generation of conventional type 1 dendritic cells, and dendritic cell priming for cross-presentation to CD8+ T cells.

    “our findings corroborate a wealth of emerging evidence that NOD2 stimulation by MDP and its analogs can alter host immunity through multiple pathways including the direct activation of macrophages for tumor cell clearance (39), epigenetic reprogramming of monocytes (40, 41), generation of conventional type 1 dendritic cells (42), and priming of dendritic cells for cross-presentation to CD8+ T cell”

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.
