Neuronal ceroid lipofuscinoses (NCLs), a group of genetically distinct fatal neurodegenerative disorders with no treatment or cure, are clinically characterised by progressive motor and visual decline leading to premature death. While the underlying pathological mechanisms are yet to be precisely determined, the diseases share several common features including inflammation, lysosomal lipofuscin deposits and lipid abnormalities. An important hallmark of most common neurodegenerative disorders including Alzheimer's, Parkinson's and motor neuron diseases is deregulation of biologically active metal homeostasis. Metals such as zinc, copper and iron are critical enzyme cofactors and are important..View full abstract
