Importantly, a positive delayed-type hypersensitivity (DTH) reaction against TRIMEL after vaccination, correlated with patients prolonged survival. Furthermore, we observed that DTH reaction was associated with a differential response pattern reflected in the presence of distinct cell subpopulations in peripheral blood. Detected variations in patient responses encouraged molecular studies aimed to identify gene expression profiles induced after vaccination in treated patients, allowing the identification of new molecular predictive markers.<h4>MethoOncotarget17014-17027https://www.ebi.ac.uk/biostudies/studies/S-EPMC5908302biostudies-literatureMolecular signatures associated with tumor-specific immune response in melanoma patients treated with dendritic cell-based immunotherapy.PMC5908302Gonzalez FEGleisner MAGarcia-Salum TLopez MNSalazar-Onfray FPereda CBaeza MMatthaus FVillablanca ANorgauer JTittarelli AGebicke-Haerter PJHoheisel JDfalseMolecular signatures associated with tumor-specific immune response in melanoma patients treated with dendritic cell-based immunotherapy.<h4>Purpose</h4>We previously showed that autologous dendritic cells (DCs) loaded with an allogeneic heat shock (HS)-conditioned melanoma cell-derived lysate, called TRIMEL, induce T-cell-mediated immune responses in stage IV melanoma patients.
