Abstract

Glycogen storage disease type Ia (GSD-Ia) patients deficient in glucose-6-phosphatase-α manifest a disturbed glucose homeostasis. We hypothesized that disturbed glucose homeostasis might affect myeloid functions. Here, we show that GSD-Ia mice exhibit normal neutrophil activities but have elevated myeloid progenitor cells in the bone marrow and spleen. Interestingly, GSD-Ia mice exhibit a persistent increase in peripheral blood neutrophil counts along with elevated serum levels of granulocyte colony stimulating factor and cytokine-induced neutrophil chemoattractant. Taken together, our results suggest that a loss of glucose homeostasis can compromise the immune system, resulting in neutrophilia. This may explain some of the unexpected clinical manifestations seen in GSD-Ia.
