OBJECTIVES Single-agent immunotherapy is ineffective against poorly immunogenic cancers, including pancreatic ductal adenocarcinoma (PDAC). The aims of this study were to demonstrate the feasibility of production of novel autologous tumor lysate vaccines from resected PDAC tumors, and verify vaccine safety and efficacy. METHODS Fresh surgically resected tumors obtained from human patients wer...
BACKGROUND Medullary thyroid carcinoma (MTC) is a calcitonin-producing tumor of the parafollicular C-cells, accounting for 5-10% of all thyroid tumors. To date, the only effective treatment is the early and total surgical removal of all neoplastic tissue. As the prognosis of patients with advanced MTC, unresectable or distant metastases is poor, and chemotherapy or irradiation is of no signific...
background: leydig cell tumor is a rare form of testicular neoplasm which comprises 1-3% of all testicular tumors and only about 3% of these tumors are bilateral. a few leydig all tumor have been described in patients with klinefelter�s syndrome so far. case: the patient described in this case report was a 24 year-old man with chief complaint of infertility for one year. physical examination, s...
BACKGROUND The prognosis of glioblastoma (GBM) remains poor; therefore, effective therapeutic strategies need to be developed. CD40 is a costimulatory molecule whose agonistic antibody has been shown to activate antitumor effects. Recently, CD40 has been extensively targeted for immunotherapeutic purposes. METHODS Expressions of CD40/CD40L mRNAs were examined in 86 cases of World Health Organ...
objective: the aim of the present study was to investigate the effect of protein and dna components of toxoplasma gondii on maturation of dendritic cells and their efficiency in il-12 production and proliferation of t cells. materials and methods: for dc generation, bone marrow cells were cultured in the presence of gm-csf and il-4 for 5 days. tumor lysate and protein or dna components of toxo...
Results from multiple human studies have continued to spur the development of dendritic cells (DCs) as therapeutic vaccines for the treatment of cancer, chronic viral infections, and autoimmune diseases. The antigen-specific activity of DCs is dependent on the ability of the DCs to take up and process tumor-associated antigens for presentation to the immune system. Although immature DCs have be...
In this research, we investigated the cytotoxic mechanisms of Cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.This micro algae is responsible for a severe and widespread harmful algal bloom in the Persian Gulf and Gulf of Oman (2008-2009). Isolated hepatocytes were obtained by collagenase perfusion of Sprague-Dawley rat liver.According to our results, incubation of algal...
Cell-mediated immunity plays an important role in immunity to the pathogenic fungus Cryptococcus neoformans. However, the antigen specificity of the T-cell response to C. neoformans remains largely unknown. In this study, we used two approaches to determine the antigen specificity of the T-cell response to C. neoformans. We report here that a diverse T-cell receptor (TCR) Vbeta repertoire was m...
