Dendritic cells (DCs) enhance their metabolic dependence on glucose and glycolysis to support their maturation, activation-related cytokine manufacturing, and T-cell stimulatory capacity. We have previously shown that this increase in glucose metabolism might be initiated by both Toll-like receptor (TLR) and C-kind lectin receptor (CLR) agonists. As well as, we've got proven that the TLR-dependent demand for glucose is partially glad by intracellular glycogen stores. However, the role of glycogen metabolism in supporting CLR-dependent DC glycolytic demand has not been formally demonstrated. On this work, we've got proven that DCs activated with fungal-related _-glucan ligands exhibit acute glycolysis induction that depends on glycogen metabolism. Furthermore, glycogen metabolism supports DC maturation, inflammatory cytokine manufacturing, and priming of the nucleotide-binding domain, leucine-rich-containing family, pyrin area-containing-three (NLRP3) inflammasome in response to each TLR- and CLR-mediated activation. These data help a model by which different lessons of innate immune receptors functionally converge of their requirement for glycogen-dependent glycolysis to metabolically support early DC activation. These studies provide new perception into how DC immune effector perform is metabolically regulated in response to diverse inflammatory stimuli.
