The cell-intrinsic capacity of neurons to regenerate axons requires widespread coordination of the transcriptome, activation of multiple kinases, and reorganization of the cytoskeleton. Axonal repair is also influenced by extrinsic activating factors, such as neurotrophins. Here, we found that the neurotrophin BDNF amplifies multiple neuron-intrinsic programs to foster axonal regeneration in human iPSC-derived lower motor neurons (i Show less

To identify the genetic cause of a complex syndrome characterized by autophagic vacuolar myopathy (AVM), hypertrophic cardiomyopathy, pigmentary retinal degeneration, and epilepsy. Clinical, pathologic, and genetic study. Two brothers presented with visual failure, seizures, and prominent cardiac involvement, but only mild cognitive impairment and no motor deterioration after 40 years of disease duration. Muscle biopsy revealed the presence of widespread alterations suggestive of AVM with autophagic vacuoles with sarcolemmal features. Through combined homozygosity mapping and exome sequencing, we identified a novel p.Gly165Glu mutation in CLN3. This study expands the clinical phenotype of CLN3 disease. Genetic testing for CLN3 should be considered in AVM with autophagic vacuoles with sarcolemmal features. Show less
