Resumen de: CN120858107A
Lung cancer is still the main cause of cancer-related death in the world. Although the introduction of an immune checkpoint inhibitor (ICI) makes a significant progress in lung cancer treatment, disease prognosis is still low, and a substantial portion of patients are not responsive to such therapy. The cancer vaccine can potentially provide a complementary approach to enhance anti-tumor immunity and act synergistically with ICI. Described herein are novel tumor antigens common to most lung tumor cells. Several tumor antigens described herein are derived from aberrantly expressed, non-mutated genomic sequences, such as intra-gene sequences and intergene sequences, which are not expressed in normal tissue. Nucleic acids, compositions, cells and vaccines derived from these tumor antigens are described. The use of the tumor antigens, nucleic acids, compositions, cells and vaccines for the treatment of lung cancer is also described.
