| abstractText | The mouse mutant motor neuron degeneration (mnd/mnd) has been proposed as a model of neuronal ceroid lipofuscinosis (NCL) on the basis of widespread abnormal accumulating lipopigment and neuronal and retinal degeneration. Clinically, the mutant on a C57Bl/6 genetic background shows a progressive motor abnormality starting by 6 months of age, with death prior to 12 months. When mnd is outcrossed to the AKR/J genetic background, ca. 40% of the mnd/mnd F2 progeny show early onset (onset by 4.5-5 months and death by 7 months). A congenic strain of mnd has now been produced by eight generations of backcross onto the AKR background. Mice on this background show average onset at 4 months, and most are moribund prior to 5.5 months. The early onset appears to correlate with levels of abnormal accumulating material, and should prove useful in elucidating NCL neurodegenerative mechanisms. Copyright 1999 Academic Press. |
