TDP-43 and RNA form amyloid-like myo-granules in regenerating muscle
Cytoplasmic, amyloid-like oligomeric assemblies that contain TDP-43 are increased in damaged tissues with elevated regeneration, thereby enhancing the possibility of amyloid fibre formation and/or aggregation of TDP-43 in disease.
