Abstract |
The molecular basis of gastrointestinal intolerances in a severe case of Niemann-Pick type C disease was analyzed in an intestinal biopsy specimen. The enzyme activities of intestinal sucrase-isomaltase and maltase-glucoamylase are reduced in the patient, while that of lactase is comparable to the control. The association of SI with lipid rafts is reduced in the patient's biopsy as a consequence of altered composition of membrane microdomains. As association with lipid rafts influences the intracellular transport and the enzyme activities of sucrase-isomaltase and maltase-glucoamylase, these data explain reduced carbohydrate digestion in the intestinal lumen and delineate the effect of deficient cholesterol and sphingolipid homeostasis in development of gastrointestinal symptoms in NPC patients. |
