Abstract

Pathological studies of mice homozygous for the motor neuron degeneration (Mnd) mutation show abnormalities similar to those of the human neuronal ceroid lipofuscinoses: sudanophilic, autofluorescent intraneuronal inclusions that are immunoreactive with antibodies to subunit c of mitochondrial ATP synthase. Ultrastructurally, the inclusions have the pentalaminar structure characteristic of some form of human neuronal ceroid lipofuscinosis and of canine and ovine models of neuronal ceroid lipofuscinosis. Similar inclusions are observed in many somatic organs and in the retina, which develops photoreceptor degeneration. This mutation, previously considered a model of amyotrophic lateral sclerosis, may be a useful model for molecular and genetic studies of human neuronal ceroid lipofuscinosis because mice have been well characterized genetically. Since they are inexpensive to breed and maintain, they can also be used to test therapeutic interventions.
