Résumé

Les étapes de la genèse du concept de maladie de Niemann-Pick type C en tant qu’entité spécifique et pathologie du transport intracellulaire des lipides et, en particulier, du cholestérol sont rappelées. Les découvertes récentes sur le rôle des protéines NPC1 et NPC2 dans l’export du cholesterol lysosomal et la problématique actuelle concernant la physiopathologie de la dysfonction cérébrale sont résumées. Les différentes approches du diagnostic de laboratoire de la maladie sont enfin exposées et discutées.
