BACKGROUND Adoptive immunotherapy with cytotoxic T lymphocytes (CTLs) has great potential for the treatment of some malignant cancers. Therefore, augmenting the responses of tumor-specific CTLs is significant for the adoptive immunotherapy of melanoma. This study aimed to investigate the anti-tumor response of a combination therapy employing folate-modified(More)
Detection of leukemia at the early stage with high sensitivity is a significant clinical challenge for clinicians. In the present study, we developed a sensitive detector consisting of the product of oligonucleotides hybridized with semiconductor quantum dots (QDs) to generate a stronger fluorescent signal so that leukemic cells can be captured. In the(More)
Whole tumor cell vaccines have shown much promise, but demonstrated poor efficiency in phase III trials. In this study, we modified MDA-MB‑231 tumor cells (MDA-MB‑231Gal+) to express α-1, 3-galactosyltransferase (α-1, 3-GT) protein, to potentially enhance antitumor effect of whole tumor cell vaccines. MDA-MB‑231 tumor cell vaccines were transfected with a(More)
Dendritic cells (DC) and tumor cell fusion vaccine (DC/tumor cell fusion vaccine) is considered an effective approach in cancer biotherapy. However, its therapeutic effects in early clinical trials have been suboptimal partially due to the immunosuppressive tumor environment. In this study, we used nanoparticles of folate (FA)-modified chitosan, a non-viral(More)
Adoptive therapy using tumor antigen-specific cytotoxic T lymphocytes (CTLs) is a promising approach for treatment of human cancers. Due to immune suppression in cancer patients, it is difficult for tumor antigen-specific CTLs to arrive at tumor tissues. Interferon-inducible protein-10 (IP-10) is a powerful chemokine that effectively attracts CTLs to tumor(More)
