Popis: Despite the progress in the treatment of lysosomal storage disorders (LSDs) mainly by enzyme replacement therapy, only limited success was reported in targeting the appropriate lysosomal enzyme into the brain. This prevents efficient clearance of neuronal storage, which is present in many of these disorders including alpha-mannosidosis. Here we show that the neuropathology of a mouse model for alpha-mannosidosis can be efficiently treated using recombinant human alpha-mannosidase (rhLAMAN). After intravenous administration of different doses (25-500 U/kg), rhLAMAN was widely distributed among tissues, and immunohistochemistry revealed lysosomal delivery of the injected enzyme. Whereas low doses (25 U/kg) led to a significant clearance (
