Dendritic cells (DCs) increase their metabolic dependence on glucose and glycolysis to support their maturation, activation-associated cytokine manufacturing, and T-cell stimulatory capability. We have now previously shown that this increase in glucose metabolism might be initiated by both Toll-like receptor (TLR) and C-sort lectin receptor (CLR) agonists. In addition, we have proven that the TLR-dependent demand for glucose is partially glad by intracellular glycogen shops. However, the function of glycogen metabolism in supporting CLR-dependent DC glycolytic demand has not been formally demonstrated. In this work, we have now shown that DCs activated with fungal-associated β-glucan ligands exhibit acute glycolysis induction that relies on glycogen metabolism. Furthermore, glycogen metabolism helps DC maturation, inflammatory cytokine production, and priming of the nucleotide-binding area, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) inflammasome in response to each TLR- and CLR-mediated activation. These knowledge help a mannequin in which different classes of innate immune receptors functionally converge of their requirement for glycogen-dependent glycolysis to metabolically help early DC activation. These research present new perception into how DC immune effector operate is metabolically regulated in response to various inflammatory stimuli.
