description

Previous studies have shown that B and T lymphocytes are affected in lysosomal disorders. The aim of this study was to investigate the involvement of subclasses of T lymphocytes and natural killer cells in lysosomal diseases. CD4+, CD8+, and CD56+ cells were immunomagnetically separated from peripheral blood mononuclear cells in 10 patients with various lysosomal diseases--including one patient each with infantile, late infantile, and juvenile neuronal ceroid-lipfuscinoses, two patients with mucopolysaccharidosis (MPS) type I and four patients with MPS type III, and one patient with mucolipidosis type II; all lymphocytes were studied by light and electron microscopy. Respective vacuolar or non-vacuolar lysosomal inclusions were identified in CD4+, CD8+, and CD56+ cells. Subclass-specific abnormal lysosomes could not be found. Both subclasses of T lymphocytes investigated showed nearly the same ratio of affected to non-affected cells. These results were obtained by studying a small number of different lysosomal disorders. Nevertheless, they suggest that lysosomal storage in these subclasses of immunocompetent cells might also be found in other forms of lysosomal disease.
