DC vaccine generated by ALA-PDT-induced immunogenic apoptotic cells for skin squamous cell carcinoma
نویسندگان
چکیده
Dendritic cell (DC) vaccines were generated by apoptotic squamous cell carcinoma (SCC) cells induced by 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (PDT). ALA-PDT-DC vaccine inhibited the growth of SCC in mice, indicating that immunogenic apoptotic cells can activate an effective antitumor adaptive immunity and lead to a DC vaccine-based cancer immunotherapy.

Improvement of DC vaccine with ALA-PDT induced immunogenic apoptotic cells for skin squamous cell carcinoma
Dendritic cell (DC) based vaccines have emerged as a promising immunotherapy for cancers. However, most DC vaccines so far have achieved only limited success in cancer treatment. Photodynamic therapy (PDT), an established cancer treatment strategy, can cause immunogenic apoptosis to induce an effective antitumor immune response. In this study, we developed a DC-based cancer vaccine using immuno...
متن کاملSynergistic Cytotoxic Effect of Gold Nanoparticles and 5-Aminolevulinic Acid-Mediated Photodynamic Therapy against Skin Cancer Cells
Background: Photodynamic therapy (PDT) is a promising therapeutic modality for the treatment of cancer and other diseases. In this study, the epidermoid carcinoma cell line A431 and the normal fibroblasts were used to investigate whether gold nanoparticles (GNPs) can induce an increase in cell death during PDT using 5-aminolevulinic acid (5-ALA) as a photosensitizer.Methods: Human fibroblast an...
متن کاملVitamin D3 enhances the apoptotic response of epithelial tumors to aminolevulinate-based photodynamic therapy.
Photodynamic therapy, mediated by exogenously administered aminolevulinic acid (ALA-PDT), followed by exposure to a laser or broadband light source, is a promising modality for treatment of many types of cancers; however, it remains inadequate to treat large, deep, solid tumors. In this article, we report that calcitriol, the active form of vitamin D3, can be administered before ALA as a nontox...
متن کاملTreating cutaneous squamous cell carcinoma using 5-aminolevulinic acid polylactic-co-glycolic acid nanoparticle-mediated photodynamic therapy in a mouse model
BACKGROUND Squamous cell carcinoma (SCC) is a common skin cancer, and its treatment is still difficult. The aim of this study was to evaluate the effectiveness of nanoparticle (NP)-assisted 5-aminolevulinic acid (ALA) delivery for topical photodynamic therapy (PDT) of cutaneous SCC. MATERIALS AND METHODS Ultraviolet-induced cutaneous SCCs were established in hairless mice. ALA-loaded polylact...
متن کاملLight Fractionation Significantly Increases the Efficacy of Photodynamic Therapy Using BF-200 ALA in Normal Mouse Skin
BACKGROUND Light fractionation significantly increases the efficacy of 5-aminolevulinic acid (ALA) based photodynamic therapy (PDT) using the nano-emulsion based gel formulation BF-200. PDT using BF-200 ALA has recently been clinically approved and is under investigation in several phase III trials for the treatment of actinic keratosis. This study is the first to compare BF-200 ALA with ALA in...
