Also, the antigenic epitopes of this molecule are known to be locatedwithin the tandem repeat domain of MUC-1 core protein. In this study, we analyzed the ability of 30-amino acid oligopeptides (MUC-1 peptide) derived from the MUC-1 core to elicit tumor-specific CTLs in peripheralblood mononuclear cells (PBMCs) from patients with lung cancer. To determine whether the MUC-1 peptide was presented by antigen presenting cells, peptides bound on the dendritic cells (DCs) pulsedwith the MUC-1 peptide were eluted by acid-treatment and studied for reactivity to anti-MUC-1 antibodyusing spot test. Although the eluates from the DCs pulsed with the MUC-1 peptide showed the reactivity tothe antibody, no reactivity was seen in those from the DCs pulsed with non-related peptides. The inducedCTLs using the MUC-1 peptide exhibited a strong cytotoxic activity against MUC-1-expressing target cellsin the 51Cr-release assay. A strong cytotoxic activity of the CTLs was observed against the MUC-1-transduced cell line, whereas there was a weak activity against the MUC-1 deficient parent cell line. Usingsynthetic peptides is thought to be useful to induce MUC-1 specific CTLs for the purpose of immunotherapeutictreatment of cancer.}, pages = {19--27}, title = {合成ペプチドを用いたMUC-1特異的細胞傷害Tリンパ球(CTL)の誘導}, volume = {14}, year = {1999}, yomi = {サワイ, サトル and コンタニ, ケイイチ and ハナオカ, ジュン and モリ, アツミ} }
