Embodiment

[0221] Materials and methods

[0222] cell line

[0223] PSCCA0922 (HLA-A0206) was purchased from Pharma SNP Consortium; PSC. Human B-lymphoblastoid cell line and COS7 were purchased from ATCC.

[0224] Candidate peptides derived from HIG2 or URLC10

[0225] 9-mer and 10-mer peptides derived from HIG2 or URLC10 were synthesized by Sigma (Sapporo, Japan) or Biosynthesis Inc. (Lewisville, TX) following standard solid-phase synthesis and analyzed by reverse-phase high-performance liquid chromatography (HPLC). Purification was performed. The purity (>90%) and identity of the peptides were determined by analytical HPLC and mass spectrometry analysis, respectively. Peptides were dissolved in dimethyl sulfoxide (DMSO) at 20 mg / ml and stored at -80°C.

[0226] In vitro CTL induction

[0227]Monocyte-derived dendritic cells (DCs) were used as antigen presenting cells (APCs) to induce cytotoxic T lymphocyte (CTL) responses against peptides presented on human leukocyte antige...

Abstract

The present invention provides a pharmaceutical agent or composition containing one or more peptides having the amino acid sequence of SEQ ID NO: 1 or 2, or one or more polynucleotides encoding such a peptide formulated for the treatment and / or prevention of cancer in a subject whose HLA-A antigen is HLA-A0206. Furthermore, the present invention provides a method of inducing CTL and antigen-presenting cells using such peptides, polynucleotides or pharmaceutical agents.

Description

[0001] This application is a divisional application of a Chinese invention patent application with an application date of August 14, 2009, an application number of 200980141320.6, and an invention title of "HIG2 and URLC epitope peptides and vaccines containing them". technical field [0002] priority [0003] This application claims the benefit of US Provisional Application No. 61 / 089,972, filed August 19, 2008, the entire contents of which are hereby incorporated by reference. technical field [0004] The present invention relates to the field of biological sciences, more specifically to the field of cancer treatment. Specifically, the present invention relates to novel peptides that are extremely effective as cancer vaccines, and drugs for treating and preventing tumors. Background of the invention [0005] It has been demonstrated that CD8-positive CTLs can recognize tumor-associated antigen (TAA)-derived epitope peptides appearing on major histocompatibility compl...
