Component
Expansion of myeloid-lineage progenitors in the bone marrow
Expansion of myeloid-lineage progenitors in the bone marrow. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Administration of beta-glucan as a prototypical trained-immunity-inducing agonist to mice induced expansion of progenitors of the myeloid lineage which was associated with elevated signalling by innate immune mediators such as IL-1 beta and granulocyte-macrophage colony-stimulating factor and with adaptations in glucose metabolism and cholesterol biosynthesis, and the trained-immunity-related increase in myelopoiesis resulted in a beneficial response to secondary LPS challenge and protection from chemotherapy-induced myelosuppression in mice.
