Abstract
Indirect immunofluorescence and immunoperoxidase staining of surgically removed tissues of nonlymphoid origin with monoclonal antibodies to the H and L chain of HLA-A,B,C antigens have shown that they have a more restricted tissue distribution than previously assumed. HLA-A,B,C antigens were not detected in brain cortex, cerebellum, sympathetic ganglia, hypophysis, parathyroid gland, thyroid, exocrine pancreas, hepatocytes, sperm, seminiferous tubules, or skeletal or smooth muscle. Malignant transformation of cells may be associated with appearance, changes in cellular distribution of HLA-A,B,C antigens and/or dissociation in the expression of the 2 subunits. Analysis of primary tumors and of autologous metastases showed heterogeneity in the expression of HLA-A,B,C antigens among lesions removed from different sites. The degree of heterogeneity did not correlate with the site of origin of metastases.This publication has 42 references indexed in Scilit:
