Evidence is growing for both humoral and cellular immune recognition of human tumor antigens. Antibodies with specificity for antigens initially recognized by cytotoxic T lymphocytes (CTLs), e.g., MAGE and tyrosinase, have been detected in melanoma patient sera, and CTLs with specificity for NY-ESO-1, a cancer-testis (CT) antigen initially identified by autologous antibody, have recently been i...
PURPOSE NY-ESO-1 (ESO), a tumor-specific antigen of the cancer/testis group, is presently viewed as an important model antigen for the development of generic anticancer vaccines. The ESO(119-143) region is immunodominant following immunization with a recombinant ESO vaccine. In this study, we generated DRB1*0101/ESO(119-143) tetramers and used them to assess CD4 T-cell responses in vaccinated p...
PURPOSE NY-ESO-1 belongs to a class of cancer/testis antigens and has been shown to be immunogenic in cancer patients. We synthesized a complex of cholesterol-bearing hydrophobized pullulan and NY-ESO-1 protein (CHP/ESO) and investigated the in vitro stimulation of CD8 and CD4 T cells from peripheral blood mononuclear cells in healthy donors with autologous CHP/ESO-loaded dendritic cells as ant...
NY-ESO-1 mRNA expression in transitional cell carcinoma was investigated by reverse transcription-PCR and immunohistochemistry. NY-ESO-1 mRNA was detected in 20 of 62 (32%) tumor specimens. There was a correlation between NY-ESO-1 expression and tumor grade: 0 of 4 (0%) grade 1 (G1), 6 of 26 (23%) grade 2 (G2), and 14 of 32 (44%) grade 3 (G3) tumors were NY-ESO-1 mRNA positive. Immunohistochemi...
NY-ESO-1 is one of the most immunogenic cancer antigens known to date, eliciting spontaneous immune responses in approximately 50% of patients with NY-ESO-1+ cancers. Spontaneous CD4+ and CD8+ T cell responses were found in patients with detectable NY-ESO-1 serum antibody, indicating an integrated type of immune response induced by NY-ESO-1+ malignancies. A close association between spontaneous...
PURPOSE The cancer/germline antigen NY-ESO-1 is variably expressed in epithelial ovarian cancer (EOC), with most tumors showing low or heterogeneous expression, which limits patient responses to NY-ESO-1 vaccine therapy. We tested the hypothesis that promoter and global genomic DNA methylation status correlates with intertumor and intratumor NY-ESO-1 expression status in EOC. EXPERIMENTAL DES...
NY-ESO-1 is a cancer/testis antigen expressed in normal adult tissues solely in the testicular germ cells of normal adults and in various cancers. It induces specific humoral and cellular immunity in patients with NY-ESO-1-expressing cancer. The aim of this study was to determine the frequency of NY-ESO-1 mRNA and protein expression in malignant and benign breast tumors. NY-ESO-1 mRNA expressio...

NY-ESO-1 is one of the most immunogenic cancer antigens known to date, inducing humoral and cellular immune responses in a high proportion of patients with advanced NY-ESO-1-expressing cancers. The assessment of spontaneous and vaccine-induced CD8+ T cell responses has been limited to a small number of known NY-ESO-1 epitopes presented by MHC class I alleles. Recently, a new method to monitor N...
