abstractText | The glycosphingolipidosis, Gaucher disease, in which a range of neurological manifestations occur, results from a deficiency of acid beta-glucocerebrosidase, with subsequent accumulation of beta-glucocerebroside, its upstream substrates, and the non-acylated congener beta-glucosylsphingosine. However, the mechanisms by which end-organ dysfunction arise are poorly understood. Here, we report strikingly diminished cerebral microvascular density in a murine model of disease, and provide a detailed analysis of the accompanying cerebral glycosphingolipidome in these animals, with marked elevations of beta-glucosylsphingosine. Further in vitro studies confirmed a concentration-dependent impairment of endothelial cytokinesis upon exposure to quasi-pathological concentrations of beta-glucosylsphingosine. These findings support a premise for pathogenic disruption of cerebral angiogenesis as an end-organ effect, with potential for therapeutic modulation in neuronopathic Gaucher disease.
