abstract = {Trained innate immunity fosters a sustained favorable
response of myeloid cells to a secondary challenge, despite
their short lifespan in circulation. We thus hypothesized
that trained immunity acts via modulation of hematopoietic
stem and progenitor cells (HSPCs). Administration of
β-glucan (prototypical trained-immunity-inducing agonist)
to mice induced expansion of progenitors of the myeloid
lineage, which was associated with elevated signaling by
innate immune mediators, such as IL-1β and
granulocyte-macrophage colony-stimulating factor (GM-CSF),
and with adaptations in glucose metabolism and cholesterol
biosynthesis. The trained-immunity-related increase in
myelopoiesis resulted in a beneficial response to secondary
LPS challenge and protection from chemotherapy-induced
myelosuppression in mice. Therefore, modulation of myeloid
progenitors in the bone marrow is an integral component of
trained immunity, which to date, was considered to involve
functional changes of mature myeloid cells in the
periphery.},
