Using an immunofluorescence (IF) assay, the presence of metallothionein (MT) was investigated in sections of normal and pathologic human thymuses as well as in cultures of thymic epithelial cells. This protein, known to have a high binding affinity for class II B transitional metals, such as zinc, was detected in the epithelial component of the thymus. Moreover, double labeling experiments with the anti-MT and an anti-thymulin monoclonal antibody showed that all cells containing thymulin, a thymic hormone whose active structure is known to contain zinc, also exhibited large amounts of metallothionein. These results, together with the fact that zinc and thymulin have been detected in the same type of cell organelles, lead to the conclusion that the MT present in thymic epithelial cells might be involved in the mechanism of zinc storage in these cells, thus favoring the secretion of thymulin in its biologically active, zinc-containing form.
