Malignant Tumor
Conditions
Brief summary
Tumor-specific antigens can be induced by demethylation drugs. Antigen-targeting DC-CTL cells supposed to eliminate cancer cells efficiently and specifically. In this study investigators co-culture DCs cells with peptides derived from tumor specific antigen to generate antigen-specific DC-CTLs (Ag-CTL). Following treatment with demethylation drugs, Ag-CTL will be used to eliminate tumor cells. This study aims to evaluate the effectiveness and safety of Ag-CTL combined with demethylation drugs.
Detailed description
A large number of studies have confirmed that demethylated drug decitabine can effectively induce tumor-specific antigen expression. Tumor-specific antigens have strong specificity and are ideal therapeutic targets. In this study, tumor-specific antigens were used as therapeutic targets. The researchers screened the tumor-specific epitope peptides through bioinformatics database combined with in vitro experiments. The peptide-loaded DCs are co-cultured with T lymphocytes to induce the proliferation of CTLs, which are then refusion to tumor patients to treating diseases.
