Cellular deposits of oxidized and aggregated proteins are hallmarks of a variety of age-related disorders, but whether such proteins contribute to pathology is not well understood. We previously reported that oxidized proteins form lipofuscin/ceroid-like bodies with a lysosomal-type distribution and
