CDw60 is a recently described T-cell antigen, which functionally delivers a costimulatory signal in T-cell activation. In addition, CDw60 has been regarded as a melanoma-associated antigen. To date, only limited information exists on the distribution of CDw60 in other normal and pathologically altered tissues in human. In the present study, the expression of CDw60 was analysed immunohistologically in a large panel of formalin-fixed and paraffin-embedded normal and pathological human tissues. The antigen was detected in several normal tissues, such as epithelia of the reproductive system, exocrine and endocrine glands, glial cells and neurons of the central and peripheral nervous systems, and lymphoid cells. These showed different subcellular distribution patterns, i.e. (1) cell surface labelling of peripheral lymphocytes and lymphocytes of the lymph node and thymus, (2) diffuse cytosolic staining in lymphocytes, subpial glial processes, and the outer plexiform layer of the retina, (3) granular cytoplasmic staining associated with the Golgi apparatus in epithelial cells of certain endocrine and exocrine glands, of the ductus epididymis and deferens, neurons of the peripheral and central nervous system, and lymphocytes and megakaryocytes of the bone marrow. In exocrine glands, e.g. of the prostate and uterine corpus, CDw60-positive Golgi fields were located in the juxtaluminal cell compartment, thus reflecting a polarized distribution. In some malignant tumours, the neoplastic cells contained CDw60-immunolabelled Golgi complexes, which were disorderly distributed throughout the cytoplasm, thus reflecting a loss of epithelial polarity. Only in mammary carcinomas was abnormal cell surface labelling detected. A putative de novo expression of CDw60 was observed in pleomorphic adenoma and mucoepidermoid carcinoma of the parotid gland, seminoma, embryonal and teratocarcinoma of the testis, small cell carcinoma of the lung, and malignant melanoma. These results define the CDw60 determinant as a broadly distributed antigen within a large panel of normal human tissues. The antigen is also detectable in some previously undescribed benign and malignant tumours, which may give importance to CDw60 as a possible diagnostic marker.
