Thyroid malignant neoplasm develops from follicular or parafollicular thyroid cells. A higher proportion of anaplastic thyroid cancer has an adverse prognosis. New drugs are being used in clinical treatment. However, for advanced thyroid malignant neoplasm such as anaplastic thyroid carcinoma, the major impediment to successful control of the disease is the absence of effective therapies. Oncol...

The complexity of the immune responses is a major challenge in current virotherapy. This study incorporates the innate immune response into our basic model for virotherapy and investigates how the innate immunity affects the outcome of virotherapy. The viral therapeutic dynamics is largely determined by the viral burst size, relative innate immune killing rate, and relative innate immunity deca...

Virotherapy can potentially be used to induce tumor-specific immune responses and to overcome tumor-mediated tolerance mechanisms because apoptotic tumor cells are exposed together with viral danger signals during oncolysis. However, insufficient numbers of dendritic cells (DC) present at the site of oncolysis can limit a tumor-specific immune response and the resulting therapeutic benefit. We ...

Glioblastoma Multiforme (GBM) is a rapidly progressing brain tumor. Despite the relatively low percentage of cancer patients with glioma diagnoses, recent statistics indicate that the number of glioma patients may have increased over the past decade. Current therapeutic options for glioma patients include tumor resection, chemotherapy, and concomitant radiation therapy with an average survival ...

Virotherapy with oncolytic viruses that preferentially infect and kill cancer cells is a novel and promising strategy for cancer treatment. Newcastle disease virus (NDV), which is pathogenic in birds, has beneficial clinical effects in cancer patients. NDV virotherapy is safe and elicits an antitumor response in patients affected by different types of cancers. The selective replication of NDV i...

Gene therapy and virotherapy are among the approaches currently used to treat malignant tumors. Gene therapy and virotherapy use a specific therapeutic gene that causes death in cancer cells. In early attempts at gene therapy, therapeutic genes were driven by ubiquitous promoters such as the CMV promoter, which induce non-specific toxicity to normal cells and tissues in addition to the cancer c...

Oncolytic virotherapy is an emerging therapeutic modality for the treatment of cancer. It entails construction of viruses with the ability to selectively target and lyse tumor cells. This branch of therapy has significantly advanced in the past decade, heralded by the development of several novel viruses. Despite the initial success of oncolytic virotherapy in the preclinical setting, however, ...

Oncolytic virotherapy is the use of replication-competent viruses to treat malignancies. The potential of oncolytic virotherapy as an approach to cancer therapy is based on historical evidence that certain viral infections can cause spontaneous remission of both hematologic and solid tumor malignancies. Oncolytic virotherapy may eliminate cancer cells through either direct oncolysis of infected...

Relatively little attention has been paid to the role of virotherapy in promoting antitumor immune responses. Here, we show that CD8+ T cells are critical for the efficacy of intratumoral vesicular stomatitis virus virotherapy and are induced against both virally encoded and tumor-associated immunodominant epitopes. We tested three separate immune interventions to increase the frequency/activit...
