The expression of Fas antigen was analyzed in the peripheral blood mononuclear cells of 12 patients with adult T-cell leukemia (ATL) by flow cytometry. The induction of apoptosis in these cells by adding an anti-Fas antibody and the expression of activated T-cell surface antigens, CD25 and CD26, were also studied. It appears that the cells in ATL expressed a significantly larger number of Fas antigens than those in normal subjects (p < 0.01) and their fluorescent intensity was also shown to be much stronger in ATL (p < 0.01). The large number of ATL cells showed apoptosis in a short-term culture in the presence of the anti-Fas antibody. There was no difference in the expression of Fas antigen among ATL cells with different phenotypes of CD4+/CD8-, CD4-/CD8- and CD4+/CD8+ as well as with clinical subtypes of ATL. Interestingly, the expression of Fas and CD26 antigens showed a negative correlation (p < 0.01, r = 0.78). The strong expression of functional Fas antigen in ATL leads to the impression that anti-Fas antibody could be one of the treatment modalities for ATL which is known to be a very difficult disease to cope with.

D017209	Apoptosis	A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, i.e., DNA FRAGMENTATION. It is genetically programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

D018819	Dipeptidyl Peptidase 4	A serine protease that catalyses the release of an N-terminal dipeptide. Several biologically-active peptides have been identified as dipeptidyl peptidase 4 substrates including INCRETINS; NEUROPEPTIDES; and CHEMOKINES. The protein is also found bound to ADENOSINE DEAMINASE on the T-CELL surface and is believed to play a role in T-cell activation.

D019014	fas Receptor	A tumor necrosis factor receptor subtype found in a variety of tissues and on activated LYMPHOCYTES. It has specificity for FAS LIGAND and plays a role in regulation of peripheral immune responses and APOPTOSIS. Multiple isoforms of the protein exist due to multiple ALTERNATIVE SPLICING. The activated receptor signals via a conserved death domain that associates with specific TNF RECEPTOR-ASSOCIATED FACTORS in the CYTOPLASM. Mutations in the CD95 gene are associated with cases of autoimmune lymphoproliferative syndrome.
